eclipse maven dependencies pom file - eclipse

Hi does anybody know where do i need to setup the mahout.version property in order for eclipse to get the latest version of the dependency?
<dependency>
<groupId>org.apache.mahout</groupId>
<artifactId>mahout-core</artifactId>
<version>${mahout.version}</version>
</dependency>

if you have a super pom or parent pom.xml you can make the properties like this :
<properties>
<mahout.version>0.9</mahout.version>
</properties>

Please replace following in your pom.xml of maven build.
<dependency>
<groupId>org.apache.mahout</groupId>
<artifactId>mahout-core</artifactId>
<version>0.8</version>
</dependency>

Cannot resolve symbol 'owasp', import error in intellij

I want to use ESAPI in my project and have added following dependency in the pom.xml
pom.xml with dependency:
<dependency>
<groupId>org.owasp.encoder</groupId>
<artifactId>encoder</artifactId>
<version>1.2.3</version>
</dependency>
<dependency>
<groupId>org.owasp.esapi</groupId>
<artifactId>esapi</artifactId>
<version>2.5.0.0</version>
</dependency>
But when I import org.owasp.esapi.* intellij give me warning as shown in image.
I want to use ESAPI logger to prevent CRLF injection possibilities in log statements.
My current project uses slf4j.Logger
I am very new to this ESAPI and OWASP and have never used it and have tried from here
https://github.com/ESAPI/esapi-java-legacy/wiki/Using-ESAPI-with-SLF4J#configuring-esapi-to-use-slf4j
Please tell me if im doing something wrong and how to correctly use ESAPI in project.
Hmm. What JDK are you using with IntelliJ? Java 8 or later is required as of 2.4.0.0. That's the only thing that I can think of that would cause this behavior. Looks okay otherwise. Did you check if the esapi-2.5.0.0.jar got pulled down? Because it's either not finding that or it's not compatible with the Java version that your IntelliJ IDE is using.
Well i found that I was adding this dependency in <dependencyManagement> tag instead of <dependencies> tag, that's why it wasn't downloading from the repository.
Previous:
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.owasp.esapi</groupId>
<artifactId>esapi</artifactId>
<version>2.5.0.0</version>
</dependency>
</dependencies>
</dependencyManagement>
after fix:
<dependencies>
<dependency>
<groupId>org.owasp.esapi</groupId>
<artifactId>esapi</artifactId>
<version>2.5.0.0</version>
</dependency>
</dependencies>
Whats the difference in <dependencies> and <dependencyManagement> please refer this Differences between dependencyManagement and dependencies in Maven

Eclipse Maven dependency jar grayed out, can't import classes from it

I'm helping a friend configure a maven project with m2eclipse for the first time. We're both pretty unfamiliar with it and are encountering an issue where even though a dependency jar is showing up with packages in it under "maven dependencies" in the Project directory, if we try to import anything from any of that jar's packages, it can't find the class.
I noticed that the jars that are having issues are gray and not as opaque as the rest of the jars that are working.
What's strange is if you hover of the class name in the import, it shows a brief description of the class (from the documentation in the jar!) but it won't let me import it. All the other maven dependencies can be imported fine. Any ideas? We can't seem to even find what the darker icon means.
Also, the pom.xml is dead simple:
http://maven.apache.org/xsd/maven-4.0.0.xsd">
4.0.0
<groupId>com.something.portal.test</groupId>
<artifactId>PortalFrontEndTests</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>
<name>PortalFrontEndTests</name>
<url>http://maven.apache.org</url>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
<!-- Selenium -->
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-java</artifactId>
<version>2.53.1</version>
</dependency>
<!-- TestNG -->
<dependency>
<groupId>org.testng</groupId>
<artifactId>testng</artifactId>
<version>6.11</version>
<scope>test</scope>
</dependency>
</dependencies>
</project>
I'm not sure what I'm missing here
open your pom.xml file
check for the name of the grayed out jar file
change
<scope>test</scope>
to
<scope>compile</scope>
I found the issue. It was because I had the class in the source directory instead of the test directory and both of the maven dependencies had been marked as "Visible only to test"
I had the same problem when i used the <scope>test</scope> in the maven pom.
It seems as if the newer Eclipse/Java versions do have a new Attribute :
<classpathentry kind="src" output="target/test-classes" path="src/test/java/...">
<attributes>
<attribute name="test" value="true"/>
</attributes>
</classpathentry>
This should be enabled in the Java Build Path Settings:
Image showing "Containts test sources" option from build path menu
After enabling this i got rid of all the compiler errors.
check for your dependency scope in POM file
compile, provided, system and test these were the available test
test -> compile would change your dependencies from grey to white.
If your dependency is for test scope then that dependency is not available for normal use in application whereas compile scope sets that dependency in class path of your project.
I am not sure on the grayed out part. If this is the feature because it suggest that Testing class should be under /test rather /src.
However, solution to your problem is scope of plugin, change it to compile and you will be good to go.
i.e. replace test with compile:
<scope>test</scope>
<scope>compile</scope>
That's it. you will not get any error for import testing packages.
Just removing the Scope will work. I tried as the following:
<dependency>
<groupId>org.junit.jupiter</groupId>
<artifactId>junit-jupiter-api</artifactId>
<version>5.8.0-M1</version>
</dependency>
I am also faced the same problem
set scope to compile or remove scope
open maven dependencies
right click on dependency and click download resources

How to resolve a pom in the dependencies list?

I am very new to Maven and am trying to use it to load the JARs I need for a web project.
I have been using the goal dependency:copy-dependencies and have set the output path to <project>\WEB-INF\libs. This has worked well so far.
I now want to intergrate the latest version of Swagger which has the following POM:
<!-- https://mvnrepository.com/artifact/io.swagger.core.v3/swagger-project -->
<dependency>
<groupId>io.swagger.core.v3</groupId>
<artifactId>swagger-project</artifactId>
<version>2.0.0-rc4</version>
<type>pom</type>
</dependency>
All this does is to load the POM to the libs folder.
Is it possible to recursively resolve POMs in the dependencies list or have I misunderstood something basic?
As has been said in the comment, take out the pom:
<!-- https://mvnrepository.com/artifact/io.swagger.core.v3/swagger-project -->
<dependency>
<groupId>io.swagger.core.v3</groupId>
<artifactId>swagger-project</artifactId>
<version>2.0.0-rc4</version>
</dependency>
The default type is jar so you don't need it, other types are pom, war, ear.
Make sure you have your proxy set in your settings.xml, which should be in ~/.m2 directory.

Maven generates old and unwanted RichFaces jars

I have a JSF 2.0 project and when I run 'mvn package' from eclipse (right click on the pom file and run) I get the war file with older versions of the richfaces jars along with the latest jars as shown in the image below.
pom.xml:
<properties>
<org.richfaces.bom.version>4.3.4.Final</org.richfaces.bom.version>
</properties>
<dependencies>
<!-- Mojarra implementation of JSF spec 2.2 -->
<dependency>
<groupId>org.glassfish</groupId>
<artifactId>javax.faces</artifactId>
<version>2.1.6</version>
</dependency>
<dependency>
<groupId>org.richfaces</groupId>
<artifactId>richfaces-bom</artifactId>
<version>${org.richfaces.bom.version}</version>
<scope>import</scope>
<type>pom</type>
</dependency>
<dependency>
<groupId>org.richfaces.ui</groupId>
<artifactId>richfaces-components-ui</artifactId>
<version>${org.richfaces.bom.version}</version>
</dependency>
<dependency>
<groupId>org.richfaces.core</groupId>
<artifactId>richfaces-core-impl</artifactId>
<version>${org.richfaces.bom.version}</version>
</dependency>
</dependencies>
How can I fix this? Any help would be appreciated.
Suggest you to install maven outside of eclipse and try to run 'mvn package' from command line and see if you encounter the same problem in this way as well.
You may also create a 'New Launch Configuration' in eclipse for running mvn package from inside eclipse. To do this, right click on the pom.xml file > Run as > Run configuration ...
Hit 'New launch configuration'. This will take care of any mis-configuration you might have done inadvertently in your earlier launch configuration.

Maven missing transitive dependency

I have a maven project with a dependency (datanucleus-db4o). This dependency has itself a dependency on db4o (db4o:db4o:jar:7.12.126.14142-all-java5).
Now maven says:
09.09.10 19:43:09 MESZ: Missing artifact db4o:db4o:jar:7.12.126.14142-all-java5:compile
I am new to maven. Is it right that datanucleus-db4o defines its own dependency with a specific version number? Is this a good way? m2eclipse can't download it. I downloaded a newer Version of db4o and added it to the classpath. Maven keeps writing about the missing artifact.
Also I've got NoClassDefFound errors when I launch my application. This leads me to the other question:
Am I doing something wrong?
Thanks in advance.
Here is the relevant part of the pom.xml...
<dependency>
<groupId>org.datanucleus</groupId>
<artifactId>datanucleus-core</artifactId>
<version>2.2.0-m1</version>
<type>jar</type>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.datanucleus</groupId>
<artifactId>datanucleus-db4o</artifactId>
<version>2.1.1</version>
<type>jar</type>
<scope>compile</scope>
</dependency>
and here is the relevant part of the pom.xml of
<dependency>
<groupId>db4o</groupId>
<artifactId>db4o</artifactId>
<version>7.12.126.14142-all-java5</version>
</dependency>
Is it right that datanucleus-db4o defines its own dependency with a specific version number? Is this a good way?
I'm not sure I understood the question... Anyway, there is indeed something wrong with the db4o:db4o dependency of the datanucleus-db4o artifact: it is not available in Maven central nor in the DataNucleus repository. I don't understand how users are supposed to use the datanucleus-db4o artifact.
I downloaded a newer Version of db4o and added it to the classpath. Maven keeps writing about the missing artifact.
Not sure what you did exactly but maybe the following will work: exclude the dependency that can't be resolved and replace it with some equivalent from the db4o repository.
<dependencies>
...
<dependency>
<groupId>org.datanucleus</groupId>
<artifactId>datanucleus-db4o</artifactId>
<version>2.1.1</version>
<type>jar</type>
<scope>compile</scope>
<exclusions>
<exclusion>
<groupId>db4o</groupId>
<artifactId>db4o</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>com.db4o</groupId>
<artifactId>db4o-full-java5</artifactId>
<version>7.12-SNAPSHOT</version>
</dependency>
</dependencies>
<repositories>
...
<repository>
<id>db4o</id>
<url>https://source.db4o.com/maven</url>
</repository>
</repositories>
I have no idea if this will work of course.
Also I've got NoClassDefFound errors when I launch my application. This leads me to the other question:
Can't say since you didn't post the error. But give the above a try.
The required file is not in the maven repositories, but it is in the datanucleus zip file (that one with all dependencies). Look into the /deps folder.
I unpacked it and installed it into the local maven repository with this command:
./mvn install:install-file -Dfile=/home/myUser/Downloads/db4o-7.12.126.14142-all-java5.jar -DgroupId=db4o -DartifactId=db4o -Dversion=7.12.126.14142-all-java5 -Dpackaging=jar
After that it is found by maven. Now there are other problems going on. I'll try to solve them myself...
Seems like the JDO or Datanucleus stuff is not well organized at the moment. I think they refactored some classes and now they can't be found at some versions and implementations are incompatible with the api and such stuff.
