I have built my project with maven
All builds successful and eclipse properties generation is also successful
But when I open the project in Eclipse 4, I am getting this error
An internal error occurred during: "Loading descriptor for SALYExplorer.".
org.eclipse.emf.ecore.xmi.FeatureNotFoundException: Feature 'taglib' not found. (platform:/resource/SALYExplorer/src/main/webapp/WEB-INF/web.xml, 313, 10)
At that location I have some properties
Though the project runs smoothly and everything is fine, just while exploring the project in Navigation pane, Eclipse always throws this error box (quite annoying).
COde at that location
<taglib>
<taglib-uri>xx.tld</taglib-uri>
<taglib-location>/WEB-INF/tld/xx.tld</taglib-location>
</taglib>
and xx definations int it's file
<!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.2//EN"
"http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_2.dtd">
<taglib>
<tlib-version>1.0</tlib-version>
<jsp-version>1.2</jsp-version>
.........
</taglib>
The problem is not the taglib at all, it's just a bad error description by Eclipse.
it is the project facet vs. web.xml dtd.. their versions must match!
if the web.xml says:
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
but the project has a
"Dynamic Web Module 2.5"
then this error will occur.. change facet to 2.3 or web.xml to 2.5... in other words: they must match..
I ran into this error while trying to update a maven project in Eclipse (ALT+F5).
web.xml
<web-app xmlns="http://java.sun.com/xml/ns/javaee" version="3.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
and project facet
Dynamic Web Modul 3.0
Here is how I could fix it:
Removed all xmls-schema definition from the web-app element
<web-app>
then update the maven project (ALT+F5).
Re-insert the schema definitions and re-update project (ALT+F5).
According to jsp_2_1.xsd included from web-app_2_5.xsd, taglib tag should be in jsp-config tag:
<xsd:complexType name="jsp-configType">
<xsd:annotation>
<xsd:documentation>
The jsp-configType is used to provide global configuration
information for the JSP files in a web application. It has
two subelements, taglib and jsp-property-group.
</xsd:documentation>
</xsd:annotation>
<xsd:sequence>
<xsd:element name="taglib"
type="javaee:taglibType"
minOccurs="0"
maxOccurs="unbounded"/>
<xsd:element name="jsp-property-group"
type="javaee:jsp-property-groupType"
minOccurs="0"
maxOccurs="unbounded"/>
</xsd:sequence>
<xsd:attribute name="id" type="xsd:ID"/>
When I wrapped taglib in js-config, the error disappeared.
<jsp-config>
<taglib>
<taglib-uri>http://www.springframework.org/tags/form</taglib-uri>
<taglib-location>/WEB-INF/taglibs/spring-form.tld</taglib-location>
</taglib>
</jsp-config>
Previous parsers were probably more lenient. My config: Eclipse Luna, built-in maven 3.2.1, web.xml 2.5, Dynamic Web Project facet 2.5.
For the time being if it's just the annoying Error Message that you want to fix, then as a short-term fix take a look at disabling validation here : Eclipse 'loading descriptor' takes ages
If the above does not work, an alternative would be to use AHK (Autohotkey) which would take slightly more work at your end. (I have been using an AHK script for a couple of years now to get rid of the Eclipse Error popups that I don't care about)
Eclipse Bug 198630 was raised almost 5 years back and in that there is a comment which has an almost identical error message as the OP. (The bug itself was finally closed as not being reproducible).
I have the following questions for you :
Would it be possible for you to show us the Error log ? (To get at the error log you can either take a look at the Error Log View or by looking at the actual file : WORKSPACE_HOME/.metadata/.log. Please take a look at this for more detailed information. )
Are you using any specific Server Adapters like WebLogic or Glassfish ?
I have the following recommendations :
In the eclipse bug thread, the problem was fixed at least once by updating to a specific JST version. Hence, would it be possible for you to run an Eclipse update and see whether the problem is resolved ? (This can be done by going to Help -> Check for Updates)
Would it be possible to try importing the project in Eclipse Indigo (instead of
Juno, which you currently have) and see whether you can reproduce
the problem ? (Eclipse Indigo downloads are available here and I believe you would need the Java EE version)
I just got the same symptoms, with a web-app project using maven. In my case, was related to struts taglib tags in web.xml, and the project having a struts v1.2.9 dependency. I solved the problem by switching to struts v1.3.10. Don't ask why this solved the problem.
If you are in the same situation and you upgrade your struts dependency from 1.2.9 to 1.3.10, be sure to use at least dtd v2.3 in the DOCTYPE declaration of your web.xml:
!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/j2ee/dtds/web-app_2_3.dtd"
or you'll get another problem (your webapp won't startup without an internet connection)
Hope this helps
I suspect that the problem is with Eclipse web Tools Platform and Java EMF Model. Here is an image of a list of plugins including Java EMF Model and JEM stuff from Eclipse Web Tools Platform:

I managed to fix this by removing the validator out of the .project file for each of the projects that had the issue.
I had a similar error using eclipse 4.3 (Kepler), maven 3.1.0, tomcat 6.0.37 and jdk7 (have also jre6 installed), and found a solution to fix it or at least to get rid of the tedious errors by configuring tomcat in eclipse.
In Preferences->Server-> Runtime Environments, define a new run time environment "Apache Tomcat 6.0" and select the jre6 installation from the installed JREs.
Then review the Targeted Runtimes in the project's properties. Apache Tomcat v6.0 should be associated with Java Runtime Environment v1.6 (if not yet defined press new and check that the selected JRE is a java 1.6 runtime).
Hope it helps
I was able to update the project Java facet to 1.5 and the errors stopped.
In my case, this problem got resolved by using the version
org.eclipse.emf.ecore.xmi_2.10.2.v20150123-0348 and org.eclipse.emf.ecore.xmi.source_2.10.2.v20150123-0348 and
org.eclipse.emf.ecore.xmi_2.10.2.v20150123-0348 and
org.eclipse.emf.ecore.xmi.source_2.10.2.v20150123-0348 and
org.eclipse.emf.common_2.10.1.v20150123-0348
jars in the build path.
Earlier jars of old version were being used inspite of new version present.
Right click on the project in Eclipse -> Build Path -> Configure Build Path -> Project Facets -> Uncheck Dynamic Web Module
Note: This approach is good as long you dont plan to run the web-app from within eclipse thru an embedded app server.
We have a project set up with maven for resolving dependancies. It usually works fine, but now I am trying to compile and run it on a new PC and I have problem with missing dependencies in Eclipse.
What is funny is that if I run "mvn package" in console or in eclipse, it works fine and even produces war containing all necessary jars. Only Eclipse complains with "The project was not built since its build path is incomplete. Cannot find the class file for org.slf4j.Logger...". If I compare the project with some other computer (where project works fine), I notice that there are quite a few libraries missing under "Maven dependencies" listing in Eclipse. Eventhough they are in the packaged war and they can be found also under repository folder.
So, the jar-s are there just Eclipse won't list them all under "Maven dependencies". What can I do?
Computer is running on Windows 7 with 64bit java & eclipse.
Well, I tried everything posted here, unfortunately nothings works in my case. So, trying different combinations I came out with this one that solved my problem.
1) Open the .classpath file at the root of your eclipse's project.
2) Insert the following entry to the file:
<classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER">
<attributes>
<attribute name="maven.pomderived" value="true"/>
<attribute name="org.eclipse.jst.component.nondependency" value=""/>
</attributes>
</classpathentry>
Then, rebuild your project at eclipse (Project->Clean-Build).
You now can check at the Java Build Path of you project at the Libraries tab the Maven Dependencies included:
Problem solved!
I don't know what exactly solved it, but I did 4 things in Eclipse:
Window->Preferences: Maven->Installations: Global settings -> open file and hardcoded localRepository
Project->Clean
right click on project: Maven->Update dependencies
right click on project: Maven->Update project configuration
I guess it was the Update dependencies since right after first two there were no change.
I'm also new to Eclipse, and I've been having a similar problem where Eclipse just won't recognize an import statement, even though all signs point to the dependency having been successfully downloaded.
You should check that your dependency file has actually been downloaded by going to the command line and typing
mvn dependency:tree
If you see your package there, then but Eclipse doesn't acknowledge it, the thing that works for me (sometimes) is to go to the terminal, cd into the project folder, and type
mvn eclipse:clean
then
mvn eclipse:eclipse
Finally refresh project in eclipse
I don't know why this works, and sometimes it doesn't work once, then doing it again does work... so worth a try!
I had this issue for dependencies that were created in other projects. Downloaded thirdparty dependencies showed up fine in the build path, but not a library that I had created.
SOLUTION: In the project that is not building correctly,
Right-click on the project and choose Properties, and then Maven.
Uncheck the box labeled "Resolve dependencies from Workspace
projects"
Hit Apply, and then OK.
Right-click again on your project and do a Maven->Update Snapshots
(or Update Dependencies)
And your errors should go away when your project rebuilds (automatically if you have auto-build enabled).
My Project was just screwed up. Here is how I fixed it for Eclipse Indigo x64 (J2EE 3.7.3):
Deleted my POM file (backedup of course).
Project Context Menu > Maven > Disable Maven Nature.
Deleted the project (but not contents on disk).
Re-imported as Import > General > Existing Project.
Project Context Menu > Configure > Convert to Maven Project....
Accept defaults from Maven wizard.
Overwrite POM with your backedup POM. (Now you have Maven Dependencies folder).
Maven Update/Clean for good measure.
Hope that helps someone. :)

Then, rebuild your project at eclipse (Project->Clean-Build).
For me the problem was maven couldn't find the settings.xml file which is located in myMavenFolder\conf.
What I did to fix the issue was to select the right location of the settings.xml file from eclipse:
Window -> Preferences -> Maven -> User Settings
Finally, hit apply and update your project
Just in case anybody has tried all the other options and you are still stuck, try right-clicking on the project folder, head over to Maven option and click the "add dependency" button. For some reason Eclipse isn't updating the dependencies manually from the pom.xml at first try.
I had a similar problem. I solved it by running the Maven->Update Project Configuration action
So I'm about 4 or 5 years late to this party, but I had this issue after pulling from our repo, and none of the other solutions from this thread worked out in my case to get rid of these warnings/errors.
This worked for me:
From Eclipse go to to Window -> Preferences -> Maven (expand) -> Errors/Warnings. The last option reads "Plugin execution not covered by lifecycle configuration" - use the drop-down menu for this option and toggle "Ignore", then Apply, then OK. (At "Requires updating Maven Projects" prompt say OK).
Further Info:
This may not necessarily "fix" the underlying issue(s), and may not qualify as "best practice" by some, however it should remove/supress these warnings from appearing in Eclipse and let you move forward at least. Specifically - I was working with Eclipse Luna Service Release 1 (4.4.1) w/ Spring Dashboard & Spring IDE Core (3.6.3), and m2e (1.5) installed, running on Arch Linux and OpenJDK 1.7. I imported my project as an existing maven project and selected OK when warned about existing warnings/errors (to deal with them later).
(Sorry, I'm not a designer, but added picture for clarity.)
For the following steps worked in my case:
1 On eclipse, right click on the desired project Maven -> Disable Maven Nature
2 Right click again then go to Properties. Delete every evidence of external Maven dependency leaving only JRE System Library.
3 Right click one more time on the project then go to Configure -> Convert to Maven Project
None of the solutions above worked for me, so this answer is for anyone else in my situation. I eventually found the problem myself, and a different solution. The pom.xml file contained a dependencyManagement tag that wrapped the dependencies, and M2Eclipse would not add the Maven Dependencies folder when this was present. So, I removed this tag, then carried out the solution offered by Ualter Jr., and Eclipse immediately added the missing folder!
Here is the steps which i followed.
1. Deleted maven project from eclipse.
2. Deleted all the file(.setting/.classpath/target) other than src and pom from my source folder.
3. imported again as a maven project
4. build it again, you should be able to see maven dependencies.
This is how I solved it
Window->Preferences: Maven->User Settings (Click on "open file" in resulting window, or just edit settings.xml with an external text editor like Notepad)
Make sure localRepository (which is displayed in this window) is correct. I had a typo in my file.
Once you have corrected settings.xml, click on Update Settings, which is on this same Preferences->Maven->User Settings screen.
Now rebuild, and it will install the latest JAR's in the correct location.
My answer is similar to that of #JerylCook: find another .classpath file in a working Maven project, edit your bad ones as that good working ones. The key is to add
<attributes>
<attribute name="maven.pomderived" value="true"/>
</attributes>
in every <classpathentry> of type con and src. Don't forget to change <classpathentry .... /> to <classpathentry ...>xxx</classpathentry>.
At last, update the maven project and reinstall/rebuild in maven.
I got this error when had an error in Pom.
Run mvn eclipse:eclipse command on console to check that pom is parsable or not.
If not parsable search for the error.
If you have "nested paths" errors after performing Maven -> Update Project Configuration (or in Juno it's "Update Configuration...") then your build path is misconfigured.
Right-click project -> Build Path -> Configure Build Path
Ensure that only '/src' and directories at that level are included. If you have e.g. '/src' and also '/src/main/resources' present, this is incorrect. The second resource ('/src/main/resources') is "nested" under the first ('/src') which is causing your inability to import resources, since it prevents eclipse from seeing maven dependencies.
My issue sounds similar so I'll add to the discussion. I had cancelled the import of an existing maven project into Eclipse which resulted in it not being allowed to Update and wouldn't properly finish the Work Space building.
What I had to do to resolve it was select Run As... -> Maven build... and under Goals I entered dependency:go-offline and ran that.
Then I right clicked the project and selected Maven -> Update Project... and updated that specific project.
This finally allowed it to create the source folders and finish the import.
I could solve the error by
1) Right click (your maven project) -> maven -> maven install
After successful installation
2) Right click (your maven project) -> maven -> update project. And the whole error of maven got solved!
For me it was sufficient add a buildCommand (org.eclipse.m2e.core.maven2Builder) and a nature (org.eclipse.m2e.core.maven2Nature) in the .project file, like this:
<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
<name>iText</name>
<comment></comment>
<projects>
</projects>
<buildSpec>
<buildCommand>
<name>org.eclipse.jdt.core.javabuilder</name>
<arguments>
</arguments>
</buildCommand>
<buildCommand>
<name>org.eclipse.m2e.core.maven2Builder</name>
<arguments>
</arguments>
</buildCommand>
</buildSpec>
<natures>
<nature>org.eclipse.jdt.core.javanature</nature>
<nature>org.eclipse.m2e.core.maven2Nature</nature>
</natures>
</projectDescription>
and I had
I had a similar issue and have tried all the answers in this post. The closest I had come to resolving this issue was by combining the Joseph Lust and Paul Crease solutions. I added the backed up pom.xml file after deleting and reimporting the project, and nothing showed up until I deleted the dependency management tag in the pom.xml and magically the dependencies folder was there.
However, it broke up the child POM's since they need the parent pom.xml dependency management to function, and as a result my MVN was not functioning properly on the project either from Eclipse or the command line, giving a broken pom.xml error.
The last solution if all fails, is to manually import the .jar files needed by your project. Right click the project Properties -> Java Build Path -> Libraries and Add external Jar.
If your MVN is working correctly from the command line and you have done a successful build on the project, you will have all the repos needed in your .m2/repository folder. Add all the external jars mentioned in your dependencies tag of pom.xml and you will see a referenced library section in your Eclipse, with all the pesky red errors gone.
This is not the optimal solution, but it will let you work in Eclipse without any errors of missing dependencies, and also allow you to build the Maven project both from Eclipse and command line.
This same problem happened to me, and it was because there an error in downloading a jar due to repo issues, indicated by a red flag in the pom.xml.
I added another repository so the red flag in the pom.xml disappeared and Eclipse then loaded the pom again, resolved its issue and listed the maven dependencies in Project Explorer. it sounds simple and obvious to resolve visible issues, but since Eclipse was quite happy to run maven, and build successfully, it was not obvious that the red flag and repo issue were at the root of its unwillingness to parse the pom and list the maven dependencies
mvn eclipse:clean
then from eclipse: "Maven Update Project" does the trick!
update the .classpath to below will work every time.
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" output="target/classes" path="src/main/java">
<attributes>
<attribute name="optional" value="true"/>

Maven Dependencies: What solved it for me in Eclipse?
I added the dependency in the "pom" file. I did a build, but could not see the Maven Dependency in the Eclipse.
Next Step: Closed the project.
Then Reopened the project.
I could see the Maven dependencies.
I experienced a similar problem lately after i created a maven project, the maven dependencies folder did not appear in the project structure.To solve this simply add any dependency in the pom file, such as in code below, or right-click on the project and go to maven and select add dependency, search for any dependency such as junit add this, and the maven dependency should appear on your project structure now.
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>4.2.9.RELEASE</version>
<scope>runtime</scope>
</dependency>
</dependencies>
Just right click over Project folder and under maven > Update project > Select your project > OK.
it will automatically download all dependencies under pom.xml to folder named Maven Dependencies.
Open the .classpath file at the root of your eclipse's project.
It's so amazing that this one problem has so many different causes and possible solutions. I found yet a different solution that worked for me.
Well, it's not so much a solution but a discovery: I can see the Maven Dependencies node in the Package Explorer, which is the default for the Java perspective, but I can not see it in the Java EE perspective, which uses the Project Explorer by default. Both of those explorers look very similar at quick glance, so you may expect to see the Maven Dependencies in both.
As I was trying to figure this out, I hadn't realized that difference, so it wasn't really a problem for me in the end after all.
the whole project looked weird in eclipse, maven dependencies folder were missing, it showed some types as unknown, but I was able to build it successfully in maven. What fixed my issue was adding gen folder to source path on project build path.
Probably this is similar to this Android /FBReaderJ/gen already exists but is not a source folder. Convert to a source folder or rename it
