How do I add local jar files (not yet part of the Maven repository) directly in my project's library sources?
You can add local dependencies directly (as mentioned in build maven project with propriatery libraries included) like this:
<dependency>
<groupId>com.sample</groupId>
<artifactId>sample</artifactId>
<version>1.0</version>
<scope>system</scope>
<systemPath>${project.basedir}/src/main/resources/Name_Your_JAR.jar</systemPath>
</dependency>
Update
In new releases this feature is marked as deprecated but still working and not removed yet ( You just see warning in the log during maven start). An issue is raised at maven group about this https://issues.apache.org/jira/browse/MNG-6523 ( You can participate and describe why this feature is helpful in some cases). I hope this feature remains there!
If you are asking me, as long as the feature is not removed, I use this to make dependency to only one naughty jar file in my project which is not fit in repository. If this feature is removed, well, there are lots of good answers here which I can chose from later!
Install the JAR into your local Maven repository (typically .m2 in your home folder) as follows:
mvn install:install-file \
-Dfile=<path-to-file> \
-DgroupId=<group-id> \
-DartifactId=<artifact-id> \
-Dversion=<version> \
-Dpackaging=<packaging> \
-DgeneratePom=true
Where each refers to:
<path-to-file>: the path to the file to load e.g → c:\kaptcha-2.3.jar
<group-id>: the group that the file should be registered under e.g → com.google.code
<artifact-id>: the artifact name for the file e.g → kaptcha
<version>: the version of the file e.g → 2.3
<packaging>: the packaging of the file e.g. → jar

Maven FAQ: I have a jar that I want to put into my local repository. How can I copy it in?
Maven Install Plugin Usage: The install:install-file goal
Firstly, I would like to give credit for this answer to an anonymous Stack Overflow user - I am pretty sure I've seen a similar answer here before - but now I cannot find it.
The best option for having local JAR files as a dependency is to create a local Maven repository. Such a repository is nothing more than a proper directory structure with pom files in it.
For my example:
I have my master project on ${master_project} location and subproject1 is on ${master_project}/${subproject1}.
Then I create a Maven repository in:
${master_project}/local-maven-repo.
In the pom file in subproject1 located at ${master_project}/${subproject1}/pom.xml, the repository needs to be specified which would take file path as a URL parameter:
<repositories>
<repository>
<id>local-maven-repo</id>
<url>file:///${project.parent.basedir}/local-maven-repo</url>
</repository>
</repositories>
The dependency can be specified as for any other repository. This makes your pom repository independent. For instance, once the desired JAR is available in Maven central, you just need to delete it from your local repo and it will be pulled from the default repo.
<dependency>
<groupId>org.apache.felix</groupId>
<artifactId>org.apache.felix.servicebinder</artifactId>
<version>0.9.0-SNAPSHOT</version>
</dependency>
The last but not least thing to do is to add the JAR file to local repository using -DlocalRepositoryPath switch like so:
mvn org.apache.maven.plugins:maven-install-plugin:2.5.2:install-file \
-Dfile=/some/path/on/my/local/filesystem/felix/servicebinder/target/org.apache.felix.servicebinder-0.9.0-SNAPSHOT.jar \
-DgroupId=org.apache.felix -DartifactId=org.apache.felix.servicebinder \
-Dversion=0.9.0-SNAPSHOT -Dpackaging=jar \
-DlocalRepositoryPath=${master_project}/local-maven-repo
Once the JAR file is installed, your Maven repo can be committed to a code repository, and the whole set-up is system independent. (Working example in GitHub).
I agree that having JARs committed to source code repo is not a good practice, but in real life, quick and dirty solutions are sometimes better than a full blown Nexus repo to host one JAR that you cannot publish.
Create a new folder, let's say local-maven-repo at the root of your Maven project.
Just add a local repo inside your <project> of your pom.xml:
<repositories>
<repository>
<id>local-maven-repo</id>
<url>file:///${project.basedir}/local-maven-repo</url>
</repository>
</repositories>
Then for each external jar you want to install, go at the root of your project and execute:
mvn deploy:deploy-file -DgroupId=[GROUP] -DartifactId=[ARTIFACT] -Dversion=[VERS] -Durl=file:./local-maven-repo/ -DrepositoryId=local-maven-repo -DupdateReleaseInfo=true -Dfile=[FILE_PATH]
I'd like such solution - use maven-install-plugin in pom file:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-install-plugin</artifactId>
<version>2.5.2</version>
<executions>
<execution>
<phase>initialize</phase>
<goals>
<goal>install-file</goal>
</goals>
<configuration>
<file>lib/yourJar.jar</file>
<groupId>com.somegroup.id</groupId>
<artifactId>artefact-id</artifactId>
<version>x.y.z</version>
<packaging>jar</packaging>
</configuration>
</execution>
</executions>
</plugin>
In this case you can perform mvn initialize and jar will be installed in local maven repo. Now this jar is available during any maven step on this machine (do not forget to include this dependency as any other maven dependency in pom with <dependency></dependency> tag). It is also possible to bind jar install not to initialize step, but any other step you like.
The really quick and dirty way is to point to a local file, please note "system" is deprecated by now:
<dependency>
<groupId>com.sample</groupId>
<artifactId>samplifact</artifactId>
<version>1.0</version>
<scope>system</scope>
<systemPath>C:\DEV\myfunnylib\yourJar.jar</systemPath>
</dependency>
However this will only live on your machine (obviously), for sharing it usually makes sense to use a proper m2 archive (nexus/artifactory) or if you do not have any of these or don't want to set one up a local maven structured archive and configure a "repository" in your pom:
local:
<repositories>
<repository>
<id>my-local-repo</id>
<url>file://C:/DEV//mymvnrepo</url>
</repository>
</repositories>
remote:
<repositories>
<repository>
<id>my-remote-repo</id>
<url>http://192.168.0.1/whatever/mavenserver/youwant/repo</url>
</repository>
</repositories>
for this solution, a relative path is also possible using the basedir variable:
<url>file:${basedir}</url>
<dependency>
<groupId>group id name</groupId>
<artifactId>artifact name</artifactId>
<version>version number</version>
<scope>system</scope>
<systemPath>jar location</systemPath>
</dependency>
Important part in dependency is:
${pom.basedir} (instead of just ${basedir})
<dependency>
<groupId>org.example</groupId>
<artifactId>example</artifactId>
<version>1.0</version>
<scope>system</scope>
<systemPath>${pom.basedir}/src/lib/example.jar</systemPath>
</dependency>
Add your own local JAR in POM file and use that in maven build.
mvn install:install-file -Dfile=path-to-jar -DgroupId=owngroupid -DartifactId=ownartifactid -Dversion=ownversion -Dpackaging=jar
For example:
mvn install:install-file -Dfile=path-to-jar -DgroupId=com.decompiler -DartifactId=jd-core-java -Dversion=1.2 -Dpackaging=jar
Then add it to the POM like this:
Step 1: Configure the maven-install-plugin with the goal install-file in your pom.xml
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-install-plugin</artifactId>
<executions>
<execution>
<id>install-external-non-maven-jar-MWS-Client-into-local-maven-repo</id>
<phase>clean</phase>
<configuration>
<repositoryLayout>default</repositoryLayout>
<groupId>com.amazonservices.mws</groupId>
<artifactId>mws-client</artifactId>
<version>1.0</version>
<file>${project.basedir}/lib/MWSClientJavaRuntime-1.0.jar</file>
<packaging>jar</packaging>
<generatePom>true</generatePom>
</configuration>
<goals>
<goal>install-file</goal>
</goals>
</execution>
</executions>
</plugin>
Make sure to edit the file path based on your actual file path (recommended is to place these external non-maven jars inside some folder, let's say lib, and place this lib folder inside your project so as to use project-specific relative path and avoid adding system specific absolute path.
If you have multiple external jars, just repeat the <execution> for other jars within the same maven-install-plugin.
Step 2: Once you have configured the maven-install-plugin as shown above in your pom.xml file, you have to use these jars in your pom.xml as usual:
<dependency>
<groupId>com.amazonservices.mws</groupId>
<artifactId>mws-client</artifactId>
<version>1.0</version>
</dependency>
Note that the maven-install-plugin only copies your external jars to your local .m2 maven repository. That's it. It doesn't automatically include these jars as maven dependencies to your project.
It's a minor point, but sometimes easy to miss.
One way is to upload it to your own Maven repository manager (such as Nexus). It's good practice to have an own repository manager anyway.
Another nice way I've recently seen is to include the Maven Install Plugin in your build lifecycle: You declare in the POM to install the files to the local repository. It's a little but small overhead and no manual step involved.
http://maven.apache.org/plugins/maven-install-plugin/install-file-mojo.html
Of course you can add jars to that folder. But maybe it does not what you want to achieve...
If you need these jars for compilation, check this related question: Can I add jars to maven 2 build classpath without installing them?
Also, before anyone suggests it, do NOT use the system scope.
Another interesting case is when you want to have in your project private maven jars. You may want to keep the capabilities of Maven to resolve transitive dependencies. The solution is fairly easy.
Create a folder libs in your project
Add the following lines in your pom.xml file
<properties><local.repository.folder>${pom.basedir}/libs/</local.repository.folder>
</properties>
<repositories>
<repository>
<id>local-maven-repository</id>
<url>file://${local.repository.folder}</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>true</enabled>
</snapshots>
</repository>
</repositories>
Open the .m2/repository folder and copy the directory structure of the project you want to import into the libs folder.
E.g. suppose you want to import the dependency
<dependency>
<groupId>com.mycompany.myproject</groupId>
<artifactId>myproject</artifactId>
<version>1.2.3</version>
</dependency>
Just go on .m2/repository and you will see the following folder
com/mycompany/myproject/1.2.3
Copy everything in your libs folder (again, including the folders under .m2/repository) and you are done.
Add local jar libraries, their sources and javadoc to a Maven project
If you have pre-compiled jar files with libraries, their sources and javadoc, then you can install them to your local Maven repository like this:
mvn install:install-file
-Dfile=awesomeapp-1.0.1.jar \
-DpomFile=awesomeapp-1.0.1.pom \
-Dsources=awesomeapp-1.0.1-sources.jar \
-Djavadoc=awesomeapp-1.0.1-javadoc.jar \
-DgroupId=com.example \
-DartifactId=awesomeapp \
-Dversion=1.0.1 \
-Dpackaging=jar
Then in your project you can use this libraries:
<!-- com.example -->
<dependency>
<groupId>com.example</groupId>
<artifactId>awesomeapp</artifactId>
<version>1.0.1</version>
</dependency>
See: maven-install-plugin usage.
Or you can build these libraries yourself with their sources and javadoc using maven-source-plugin and maven-javadoc-plugin, and then install them.
Example project: library
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

Execute maven install goal:
mvn install
Check your local Maven repository:
~/.m2/repository/com/example/awesomeapp/1.0.1/
├─ _remote.repositories
├─ awesomeapp-1.0.1.jar
├─ awesomeapp-1.0.1.pom
├─ awesomeapp-1.0.1-javadoc.jar
└─ awesomeapp-1.0.1-sources.jar
Then you can use this library:
<!-- com.example -->
<dependency>
<groupId>com.example</groupId>
<artifactId>awesomeapp</artifactId>
<version>1.0.1</version>
</dependency>
command line :
mvn install:install-file -Dfile=c:\kaptcha-{version}.jar -DgroupId=com.google.code
-DartifactId=kaptcha -Dversion={version} -Dpackaging=jar
I think a better solution for this problem is to use maven-install-plugin to automatically install the files at install time. This is how I set it up for my project.
First, add the path (where you store the local .jars) as a property.
<properties>
<local.sdk>/path/to/jar</local.sdk>
</properties>
Then, under plugins add a plugin to install the jars when compiling.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-install-plugin</artifactId>
<version>2.5.2</version>
<executions>
<execution>
<id>1</id>
<phase>initialize</phase>
<goals>
<goal>install-file</goal>
</goals>
<configuration>
<groupId>com.local.jar</groupId>
<artifactId>appengine-api</artifactId>
<version>1.0</version>
<packaging>jar</packaging>
<file>${local.sdk}/lib/impl/appengine-api.jar</file>
</configuration>
</execution>
<execution>
<id>appengine-api-stubs</id>
<phase>initialize</phase>
<goals>
<goal>install-file</goal>
</goals>
<configuration>
<groupId>com.local.jar</groupId>
<artifactId>appengine-api-stubs</artifactId>
<version>1.0</version>
<packaging>jar</packaging>
<file>${local.sdk}/lib/impl/appengine-api-stubs.jar</file>
</configuration>
</execution>
</executions>
</plugin>
Finally, in dependencies, you can add the jars
<dependency>
<groupId>com.local.jar</groupId>
<artifactId>appengine-api</artifactId>
<version>1.0</version>
</dependency>
<dependency>
<groupId>com.local.jar</groupId>
<artifactId>appengine-api-stubs</artifactId>
<version>1.0</version>
<scope>test</scope>
</dependency>
By Setting up your project like this, the project will continue to build even when you take it to another computer (given that it has all the jar files in the path specified by the property local.sdk).
For groupId use a unique name just to make sure that there are no conflicts.
Now when you mvn install or mvn test local jars will be added automatically.
Not an answer to the original question, however it might be useful for someone
There is no proper way to add multiple jar libraries from the folder using Maven. If there are only few dependencies, it is probably easier to configure maven-install-plugin as mentioned in the answers above.
However for my particular case, I had a lib folder with more than 100 proprietary jar files which I had to add somehow. And for me it was much easier for me to convert my Maven project to Gradle.
plugins {
id 'org.springframework.boot' version '2.2.2.RELEASE'
id 'io.spring.dependency-management' version '1.0.8.RELEASE'
id 'java'
}
group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'
repositories {
mavenCentral()
flatDir {
dirs 'libs' // local libs folder
}
}
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-web'
testImplementation('org.springframework.boot:spring-boot-starter-test') {
exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
}
implementation 'io.grpc:grpc-netty-shaded:1.29.0'
implementation 'io.grpc:grpc-protobuf:1.29.0'
implementation 'io.grpc:grpc-stub:1.29.0' // dependecies from maven central
implementation name: 'akka-actor_2.12-2.6.1' // dependecies from lib folder
implementation name: 'akka-protobuf-v3_2.12-2.6.1'
implementation name: 'akka-stream_2.12-2.6.1'
}
This is a short syntax for newer versions:
mvn install:install-file -Dfile=<path-to-file>
It works when the JAR was built by Apache Maven - the most common case. Then it'll contain a pom.xml in a subfolder of the META-INF directory, which will be read by default.
Source: http://maven.apache.org/guides/mini/guide-3rd-party-jars-local.html
The preferred way would be to create your own remote repository.
See here for details on how to do it.
Have a look at the 'Uploading to a Remote Repository' section.
I want to share a code where you can upload a folder full of jars. It's useful when a provider doesn't have a public repository and you need to add lots of libraries manually. I've decided to build a .bat instead of call directly to maven because It could be Out of Memory errors. It was prepared for a windows environment but is easy to adapt it to linux OS:
import java.io.File;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Date;
import java.util.jar.Attributes;
import java.util.jar.JarFile;
import java.util.jar.Manifest;
public class CreateMavenRepoApp {
private static final String OCB_PLUGIN_FOLDER = "C://your_folder_with_jars";
public static void main(String[] args) throws IOException {
File directory = new File();
//get all the files from a directory
PrintWriter writer = new PrintWriter("update_repo_maven.bat", "UTF-8");
writer.println("rem "+ new Date());
File[] fList = directory.listFiles();
for (File file : fList){
if (file.isFile()){
String absolutePath = file.getAbsolutePath() ;
Manifest m = new JarFile(absolutePath).getManifest();
Attributes attributes = m.getMainAttributes();
String symbolicName = attributes.getValue("Bundle-SymbolicName");
if(symbolicName!=null &&symbolicName.contains("com.yourCompany.yourProject")) {
String[] parts =symbolicName.split("\\.");
String artifactId = parts[parts.length-1];
String groupId = symbolicName.substring(0,symbolicName.length()-artifactId.length()-1);
String version = attributes.getValue("Bundle-Version");
String mavenLine= "call mvn org.apache.maven.plugins:maven-install-plugin:2.5.1:install-file -Dfile="+ absolutePath+" -DgroupId="+ groupId+" -DartifactId="+ artifactId+" -Dversion="+ version+" -Dpackaging=jar ";
writer.println(mavenLine);
}
}
}
writer.close();
}
}
After run this main from any IDE, run the update_repo_maven.bat.
Also take a look at...
<scope>compile</scope>
Maven Dependencies. This is the default but I've found in some cases explicitly setting that scope also Maven to find local libraries in the local repository.
Create a local Maven repository directory, Your project root should look something like this to start with:
yourproject
+- pom.xml
+- src
Add a standard Maven repository directory called repo for the group com.example and version 1.0:
yourproject
+- pom.xml
+- src
+- repo
Deploy the Artifact Into the Repo, Maven can deploy the artifact for you using the mvn deploy:deploy-file goal:
mvn deploy:deploy-file -Durl=file:///pathtoyour/repo -Dfile=your.jar -DgroupId=your.group.id -DartifactId=yourid -Dpackaging=jar -Dversion=1.0
install pom file corresponding to your jar so that your project can find jar during maven build from local repo:
mvn install:install-file -Dfile=/path-to-your-jar-1.0.jar -DpomFile=/path-to-your-pom-1.0.pom
add repo in your pom file:
<repositories>
<!--other repositories if any-->
<repository>
<id>project.local</id>
<name>project</name>
<url>file:${project.basedir}/repo</url>
</repository>
</repositories>
add the dependency in your pom:
<dependency>
<groupId>com.groupid</groupId>
<artifactId>myid</artifactId>
<version>1.0</version>
</dependency>
To install third party jar, Please call the command like below
mvn install:install-file -DgroupId= -DartifactId= -Dversion= -Dpackaging=jar -Dfile=path
For some reason, in the web application I'm giving maintenance to, neither Alireza Fattahi's solution nor JJ Roman's solution worked correctly. In both cases, the compilation goes okay (it sees the jar), but the packaging fails to include the jar inside the war.
The only way I managed to make it work was by putting the jar on /src/main/webapp/WEB-INF/lib/ and then combining it with either Fattahis's or Roman's solution.
Note that it is NOT necessarily a good idea to use a local repo.
If this project is shared with others then everyone else will have problems and questions when it doesn't work, and the jar won't be available even in your source control system!
Although the shared repo is the best answer, if you cannot do this for some reason then embedding the jar is better than a local repo. Local-only repo contents can cause lots of problems, especially over time.
On your local repository you can install your jar by issuing the commands
mvn install:install-file -Dfile=<path-to-file> -DgroupId=<group-id> \
-DartifactId=<artifact-id> -Dversion=<version> -Dpackaging=<packaging>
Follow this useful link to do the same from mkyoung's website. You can also check maven guide for the same
mvn install
You can write code below in command line or if you're using eclipse builtin maven right click on project -> Run As -> run configurations... -> in left panel right click on Maven Build -> new configuration -> write the code in Goals & in base directory :${project_loc:NameOfYourProject} -> Run
mvn install:install-file
-Dfile=<path-to-file>
-DgroupId=<group-id>
-DartifactId=<artifact-id>
-Dversion=<version>
-Dpackaging=<packaging>
-DgeneratePom=true
Where each refers to:
< path-to-file >: the path to the file to load e.g -> c:\kaptcha-2.3.jar
< group-id >: the group that the file should be registered under e.g -> com.google.code
< artifact-id >: the artifact name for the file e.g -> kaptcha
< version >: the version of the file e.g -> 2.3
< packaging >: the packaging of the file e.g. -> jar
2.After installed, just declares jar in pom.xml.
<dependency>
<groupId>com.google.code</groupId>
<artifactId>kaptcha</artifactId>
<version>2.3</version>
</dependency>
Perhaps someone will be interested in:
https://github.com/Limraj/maven-artifact-generator
Console program to generate maven artifacts in the local repository, and configure dependencies for pom.xml, based on the path to the jars.
You can do this for one file, but it's most useful if you have multiple jar files.
path jars:
java -jar maven-artifact-generator-X.X.X.jar -p path_to_jars -g com.test -V 1.2.3 -P jar
jar:
java -jar maven-artifact-generator-X.X.X.jar -f file_jar -g com.test -V 1.2.3 -P jar
This will generate an artifact in the local maven repository, and generate dependecies for pom.xml in gen.log. ArtifactId is the name of the jar file.
Requires an installed maven.
Testing on widnows 7 and macOS X (unix/linux).

I had the same error for a set of dependencies in my pom.xml turns out the versions of the dependencies was not specified in the pom.xml and was mentioned in the parent repository. For some reason the version details was not syncing with this repo. Hence i manually entered the versions using the tag and it worked like a charm. Little bit of time needed to look up the versions in the parent and specify here. But this can be done just for the jars that are showing the artifactid error and it works. Hope this helps someone.

David Montaño... after manually marking src/test/scala as Test Sources Root, I got "Error:(11, 18) illegal cyclic inheritance" as mentioned by Rasika
I just found that scala 2.13.1 is not compatible with gatling. I removed scala 2.13.1 from global libraries list and added scala 2.12.10. Tests working fine now. Here are the steps
Right click project folder in IntelliJ and choose 'Open Module Settings'
Under 'Platform Settings' select 'Global Libraries'
Here, remove scala-sdk-2.13.1 and add scala-sdk-2.12.10
Rebuild the module
It worked for me when I manually marked the src/test/scala as Test Sources Root and rebuild the project.
Mark as Test Sources Root
It should be picked up automatically by IntelliJ but it wasn't the case.
Tied both :
marked the src/test/scala as Test Sources Root and rebuild the project.
Mark as Test Sources Root
And
Under 'Platform Settings' select 'Global Libraries'
Here, remove scala-sdk-2.13.1 and add scala-sdk-2.12.10
then works.
I firstly generated a gwt maven project by executing --
mvn archetype:generate -DarchetypeGroupId=org.codehaus.mojo
-DarchetypeArtifactId=gwt-maven-plugin -DarchetypeVersion=2.7.0
After that, the pom.xml is as follows:

Then I imported this project into eclipse via built-in eclipse function -- import existing Maven project.
However, the process failed due to several reasons:
GreetingServiceAsync cannot be resolved to a type
Execution default of goal org.codehaus.mojo:gwt-maven-plugin:2.7.0:generateAsync failed:
Plugin org.codehaus.mojo:gwt-maven-plugin:2.7.0 or one of its
dependencies could not be resolved: Failed to collect dependencies for
org.codehaus.mojo:gwt-maven-plugin:jar:2.7.0 ()
(org.codehaus.mojo:gwt-maven-plugin:2.7.0:generateAsync:default:generate-sources)
google plugin can't identify this project as gwt web application automatically.
My environment as follows:
java version 1.7.0_03
eclipse version Kepler Service Release 2
gwt version 2.7.0
Please advice, thanks a lot!
I did another attempt to try in a win32 computer, the problem re-appeared even if I set up the environment as aforementioned working in my win64 computer.
So I really got confused, like Klarki said, I have to do some tweaks to get it work. I generated GreetingServiceAsync via mvn gwt:generateAsync then manually copy GreetingServiceAsync to source folder, then I remove <goal>generateAsync</goal> in pom.xml, then import project via eclipse's existing maven project. It works again!
Sadly see it not working intelligently.
The problem was with generateAsync, which in your case generates GreetingServiceAsync on execution. Eclipse probably wasn't configured to handle it properly and this class was not generated and eclipse reported the missing class warning.
Another thing that could be done to get the project to work was to run mvn package from command line and add the generated dir in target dir as source dir in eclipse (vie right clicking the project and selecting New -> source folder > browsing folder name > target > generated-sources > the right folder)
Also you may run into same issue after you do mvn clean - the generated GreetingServiceAsync will be deleted and the problem may come back.
The problem exists because eclipse isn't tightly integrated with maven and uses its own build system ignoring maven targets that you don't have plugins for. What you could do is to open eclipse preferences > maven > lifecycle mappings and there you can enable generateAsync to execute.
If you copy the generated class manually you have to keep in mind that you need to update it when needed, where as it is intended to generate automatically. So you loose this convenience.
This work for me:
I deleted the local maven gwt repository, in windows 7 it's in C:\Users\.m2\repository\com\google\gwt, and then make a
mvn clean complile
so maven re-import al dependencys.
After I changed my environment as follows:
java version "1.8.0_05"
eclipse Version: Luna Release (4.4.0)
Google plugin for Eclipse 4.4
I works like a charm.
Probably, it's a version incompatibility issue.
I created a dynamic web application in eclipse Version: Kepler Service Release 1 using menu.
After that I converted it into a maven project using
configure -> convert to maven project. Then I did
maven->Add dependency and then searched for log4j.
After adding that on hovering over the tag
for log4j it displays Missing artifact log4j:log4j:bundle:1.2.17.
I can't update dependencies using maven. How to fix it?
Please also explain the reason for the error.
Here is the generated xml after adding log4j.

First why did you changed the default source folder location? The default is src/main/java and for webapp src/main/webapp. Apart from that a bundle for log4j does not exist on Maven Central just remove the <type>bundle</type> from your dependency, cause in Maven Central only a jar is available.
I always do the following trick:
In the dependencies management i edit the dependencies properties (select the dependencies with problem and click on properties button) changing the type from bundled to jar and that fixs the problem.
Well i hope that this solution work for you :) regards,
I too played with all the options provided above but it did not helped. By updating Maven dependencies forcefully my issue got resolved.
Go to project >> Maven >> Update Project
select the project and click OK.
Project will automatically try to download required jar but if still you are getting same error then do below step.
Go to project >> Maven >> Update Project >> check in the checkbox 'Force Update of Snapshots/Releases'
select the project and click OK.
Please check if the dependencies are correct or if it is missing.
<properties>
<springframework.version>4.2.1.RELEASE</springframework.version>
<jackson.version>2.5.3</jackson.version>
<log4j.version>1.2.17</log4j.version>
</properties>
By default (and the common usage), Maven would consume jars as a dependency. Just change the bundle to jar in your pom.xml file in the given dependency which is giving you an error.
I'm trying to get GWT Hosted mode working in Eclipse, à la this HOWTO. Servlets work fine, as does my GWT code, but all my JSPs fail because with errors such as the following:
[WARN] /view/lniExecutiveSummary.htm
org.apache.jasper.JasperException: /WEB-INF/jsp/lni/lniExecutiveSummary.jsp(1,1) The absolute uri: http://java.sun.com/jsp/jstl/fmt cannot be resolved in either web.xml or the jar files deployed with this application

This webapp works fine when deployed under Tomcat 5x; I just can't seem to get it to resolve the taglibs when running in Eclipse.
I'm new to Eclipse, and getting it working with all the moving parts required for GWT+Maven has me pulling my hair out.
Update: I'm no longer using Eclipse; I've switched (back!) to Intellij IDEA. So I can't honestly evaluate the answers you kind folks have posted. Once some voting action happens, or someone else reports success with one of these methods, I'll accept the appropriate answer. Thanks.
I feel your pain. I've gone thru the same pain trying to get gwt, maven, and eclipse to work together.
I've been able to get it working with maven using the following pom.xml. This way you can use mvn gwt:run to run in hosted mode, but unfortunately, I could never get the mvn goal mvn gwt:eclipse for generating an eclipse launch run time config to work.
Here's the relevant snippets from my pom.xml. Note that I've found it easier to install gwt in separate location and point maven to use that instead of having mvn download gwt from repo. The "system" level scope in the mvn dependencies are what make this happen.

Another technique I've had success with is to use the eclipse google gwt plugin. Just use the wizard to create a new gwt project, make sure that you can run it from eclipse, then modify with your own code.
This webapp works fine when deployed under Tomcat 5x; I just can't seem to get it to resolve the taglibs when running in Eclipse. I'm new to Eclipse, and getting it working with all the moving parts required for GWT+Maven has me pulling my hair out.
You apparently have the JSTL JAR file(s) in Tomcat/lib instead of WEB-INF/lib. You can fix this in at least three ways:
Move/copy the JSTL JAR file(s) into WEB-INF/lib.
Move/copy the JSTL JAR file(s) into Tomcat/lib of your development machine.
Associate the right Tomcat server containing the JSTL JAR file(s) with web project in Eclipse. If not done yet, add the Tomcat server in Servers view. Then in project properties go to Java Build Path > Libraries > Add Library > Server Runtime > select the server in question.
Add the Jar files in eclipse project classpath. if you already had this file tomcat lib. This option will works for you. Second option is add jar in Web-Inf lib folder if you have eclipse web project.
Did you try to mark the "jsf-api.jar" as "exported" in your Java project ?
(as mentioned in this thread)
1.) Go into the java-project properties and mark the "jsf-api.jar" as exported.
(project>properties>java build path>order and exports)
2.) Go into the advanced global tomcat preferences and add your project to
the tomcat classpath (windows>preferences>tomcat>advanced>add projects to
tomcat classpath)
Then, try again to run your webapp under eclipse.
Here is an article describing the same procedure/setup, not for JSF but Hudson (same problem though)
You can clearly see the two steps I mentioned above:
