Grails / Groovy / GGTS: Conflicting module versions on run-app - eclipse
After upgrading a Grails application from 2.2.0 to 2.2.1 I keep getting the following error when attempting to debug a Grails application from GGTS via Debug as... -> Grails Command (run-app):
Error starting Grails: nulljava.lang.ExceptionInInitializerError

I'm running GGTS 3.1.0.RELEASE with the Groovy Compiler 2.0 Feature 2.7.1.xx-20120921-2000-e42RELEASE and Groovy/Grails Tool Suite 3.1.0.201210061306-RELEASE-e42. The project has configured Groovy Compiler level 2.0. Eclipse Preferences say "You are currently using Groovy Compiler version 2.0.4.xx-20120921-2000-e42RELEASE".
Any hints?
i had this problem on Grails 2.2.0 on Ubuntu machine , i fixed it with the below steps :
open eclipse go to "Run as" the "Run Configurations"
choose "Environment" tab , then choose "replace native environment with specified environment "
that solved the problem for me .. hope this help
I had the same problem, I was picking up groovy-all 2.0.7 from GGTS and 2.0.8 from my grails project. To resolve the problem I removed the "Groovy Dependencies" library from the eclipse project.
Right click on project -> Properties -> Java Build Path -> Libraries (tab) -> Groovy Dependencies -> Remove
Manually delete the run-app Run Configuration so it gets recreated. This was reported as a bug on Aug. 1st, 2013. Bug report: https://issuetracker.springsource.com/browse/STS-3501
I deleted .metadata in GGTS workspace and reimport project. It works, I can run-app again.
I had the same exception, when I was trying to run JUnit tests on my Spring boot project in Eclipse only, mvn executes them fine. I'm not using Gradle or Groovy. Indeed checking the test's class path upon debug, showed two versions of groovy.jar. The work version of the groovy.jar was picked from other projects in the Eclipse workspace. I was able to fix it by removing Resolve dependencies from Workspace projects in project properties -> Maven
I had the same problem and i solved it by:
For your project: Open Run As->Run Configurations
Go to the Refresh tab
Check the Refresh resources upon completion
Press Run
That did the trick for me.
I solved it by removing the option to manually load the classpath in Run Configuration. It was using the wrong Grails version (2.5.0 instead of 2.5.1).
Basically the wrong classpath was used.
Maybe this brings someone on the correct path :)
I have no explanation why it didn't work, but I found a workaround.
I had another run target configured for the same app, but with a -Dgrails.env=... setting, which I could launch without problems. I simply copied this config and removed the parameter. That way, I basically recreated the simple launch config which previously kept failing.
Problem gone.
For me a compile from the grails command window did the trick
I had the same problem when running it through eclipse and what worked for me is to make the below changes
Go to Project properties -> Groovy Compiler ->configure workspace settings . Uncheck the checkbox "Enable checking for mismatch between project and workspace groovy compiler levels"
Another solution worked for me when Eclipse stopped being able to run my project with the "groovy-all is loaded in version ... and you are trying to load version" error.
Manually removing a groovy-all line from the .classpath fixed it.
<classpathentry kind="lib" path="Libraries/groovy-all-2.1.2.jar"/>
I found the solution in this blog post.
I had the same problem, I went to Project properties -> Groovy Compiler ->configure workspace settings and I clicked on the "Switch to" button that corresponded to one of the two versions in the error message.
I hope this will help
I know this is a GGTS question, but Google led me here and this seems to be a common issue even after several years so I'm posting this answer here. Hopefully it can help other STS users who also land here.
I had this problem with Spring Tool Suite, using Spring Boot Version 1.3.3.RELEASE and gradle version 2.14. There is some internal dependency on groovy 2.4.6 and groovy-all 2.4.6, but my Eclipse workspace Groovy Libraries are version 2.4.7. Removing the Groovy Libraries from the Spring/Gradle project properties(s) works for running those projects, but for other Groovy projects in the workspace you are stuck between a rock and a hard place. They will either run if you click yes when "Errors exist in project. Run anyway?" if you remove the Groovy libs from the properties build path, or they will not have project errors if you put the Groovy libs in the properties build path.
Resolved by adding explicit dependencies in build.gradle on groovy 2.4.7 and groovy-all 2.4.7 for Gradle projects in the workspace
compile('org.codehaus.groovy:groovy:2.4.7')
compile('org.codehaus.groovy:groovy-all:2.4.7')
and (close Eclipse STS) then removing the 2.4.6 folder(s) from the .gradle cache
<path to>\.gradle\caches\modules-2\files-2.1\org.codehaus.groovy\groovy\2.4.6
<path to>\.gradle\caches\modules-2\files-2.1\org.codehaus.groovy\groovy-all\2.4.6
and (Open STS) then right-click gradle project(s)>gradle>refresh gradle project
Now other Groovy projects in the workspace run without the 2.4.6 vs 2.4.7 conflict.
use mvn denpendency:tree to check your dependencies, maybe there exist version conflicts.
When I change the grails project's name it works correctly.
Currently (using Eclipse 2020-06, 4.16.0) none of the above solutions work any more.
Open the Run Configuration of your groovy script
Remove all User Entries from the Classpath tab
Press "Restore Default Entries"
This should add the default classpath containing your specified Groovy version as User Entry.

Maven run/debug configurations in Intellij
I have been using eclipse for some long time. I have previously decided to switch to intellij. There is however a feature in eclipse that I miss. When using maven, I used to have a maven clean install run config saved under my run configs. And have the base directory as ${project_loc}.
Thus when i select the project from the project explorer, I can run the maven config on it. I have found in intellij the create/run configuration dialog which has the working directory field.
My question is how can i configure this field to get the same effect as eclipse's ${project_loc} variable?
That is something Maven Helper plugin solves. It runs goals for the selected module.
Eclipse- Maven -Spring
I installed eclipse Luna.At that time Maven option was displayed in window-- preferences.Later i install spring ide.After installation maven got disappeared.pls help me to come out of this
Eclipse is well known for working oddly despite the correct settings and configuration. (As most of free IDEs'). Try to click to your project, then Configure and select Convert to Maven project. Also clicking to your project and selecting the Clean may help since it removes all the files that are generated automatically.
Eclipse running lift project (project configuration issues)
Trying to get a lift project to run on windows, I've installed maven on my computer, then tried to use mvn archetype:generate from cmd, then chose the lift basic one , but it always failed on the jetty:run part. Before that, I had to change a lot of the pom.xml file to even get a successful build (since the tutorial I was using was obsolete and it couldn't find the dependencies). So I've decided to try with the eclipse plugin, thinking it should be easier. I've installed the maven plugin for eclipse and created a project with the lift archetype. The project was succesfully created, but I have all kinds of errors in the editor for missing ; and so on (I have scala ide installed on eclipse also and creating a normal scala project works and compiles/runs fine). I have also tried to include the scala-library.jar in the buildpath, with no change. The odd part is that I can run the cmd and go to the project folder, then run mvn jetty:run and it will actually work (?!) Trying to run in eclipse with jetty:run as goal will give me ClassNotFoundException on the HelloWorld snippet. So what might be wrong with my settings? UPDATE: no luck whatsoever, after trying 3 different eclipse versions, installing the maven for scala plugin and following every tutorial I could find. It just simply feels all is outdated on the instructions: this is how it looks after I include the scala libraries for eclipse on every project (after I create it from an archetype):
is this "mvn archetype:generate" up to date? I don't know if anybody guarantees it will work at all.. Anyway, the default way to at least try Lift and see it working is the following: https://github.com/lift/lift_25_sbt It uses "Simple Build Tool" instead of maven, but maven should work, too. Also, you can easily read "build.sbt" to get all the dependencies. Plugins for creating eclipse/intellij project definitions are included. (See the README of the demo project.) The target to create eclipse project is "eclipse" or "eclipse with-sources=true". The target to launch the app is "container:start".
How to fix error "Updating Maven Project". Unsupported IClasspathEntry kind=4?
I have imported maven project in STS, when I run update update project I receive: "Updating Maven Project". Unsupported IClasspathEntry kind=4 Is there a workaround for this?
This issue has been fixed in m2e 1.5.0 which is available for Eclipse Kepler (4.3) and Luna (4.4) Please see https://bugs.eclipse.org/bugs/show_bug.cgi?id=374332#c14 The problem is caused by the fact that STS (the Spring IDE/Eclipse), as well Eclipse and other Eclipse based IDE's, use the m2e(clipse) plugin but that eclipse:eclipse has been probably been run on the project. When m2e encounters a "var" .classpath entry, it throws this error. The update sites are specified at the following url: http://eclipse.org/m2e/m2e-downloads.html If you can't use m2e 1.5.0 for any reason, then : Disable the maven nature for the project (via the right-click menu) Run mvn eclipse:clean (while your project is open in STS/eclipse). Depending on the timing, you might need to do a refresh or two on the project before re-enabling the maven nature. You should be able to see that your project has lost it's Maven nature. (The eclipse:clean goal just deletes the .project, .classpath and .settings/ files/directories. You can also just remove those files (again while the project is open) instead of running mvn eclipse:clean.) Re-enable the maven nature. (Most of the time, this can be done by right-clicking on the project in question in the package explorer pane, and then choosing 'Configure'-> 'Convert to Maven Project')
Right-click on your project, select Maven -> Remove Maven Nature. Open you terminal, go to your project folder and do mvn eclipse:clean Right click on your Project and select “Configure -> Convert into Maven Project” Now you got “Unsupported IClasspathEntry kind=4 Eclipse Scala” disappear.
Sometimes, even re-importing the Maven project will not work. Updating the project correctly in eclipse is not a deterministic process. The only 100% fail safe procedure I've found is: Disable Maven Nature, run mvn eclipse:clean, restart, cross your fingers and Pray 3 times. If this won't work, delete the project, run mvn eclipse:clean, re-import refresh, pray and use the force. If this still doesn't work, restart Eclipse, or even better your computer. While waiting for the reboot, you can make a random donation to fix your Karma. Repeat step 2 and don't forget to pray and control your anger. Anger leads to hate. Hate leads to suffering. Try all the other answers posted in this thread. You might need to try them all for 3 times at least before giving up. Format your Computer, re-install Eclipse and Maven. No need to pray anymore, all gods hate you anyway Delete your git project, burn the physical drive that stored the remote repository, and write your project from scratch. Find a time machine, travel to the past and convince yourself to follow another, non-programming career or at least to avoid Java
Make sure that the version of the m2e(clipse) plugin that you're running is at least 1.1.0 Close maven project - right click "Close Project" Manualy remove all classpathentry with kind="var" in .classpath file Open project or Remove maven project Manualy rmeove .classpath 4 Reimport project
Have you tried: If you have import project into the eclipse 4, please delete it. In maven consol, run: mvn eclipse:clean In Eclipse 4: File -> Import -> Maven -> Existing Maven Projects
Seeing all other answers. I found for me a simpler way. I just removed all lines in the .classpath (editing with eclipse) containing a var and used maven -> update project without an error.
This error is also thrown if the update command is used on a project instrumented for code coverage with Clover. To resolve in this scenario: Un-instrument the project folders you wish to update. Run the maven update then instrument for code coverage again.
I tried Marco's steps but no luck. Instead if you just get the latest m2e plugin from the link he provides and one by one right click on each project -> Maven -> Update Dependencies the error still pops up but the issue is resolved. That is to say the warnings disappear in the Markers view. I encountered this issue after importing some projects into SpringSource Tool Suite (STS). When I returned to my Eclipse Juno installation the warnings were displaying. Seeing that I had m2e 1.1 already installed I tried Marco's steps to no avail. Getting the latest version fixed it however.
I couldn't get mvn eclipse:clean etc to work with Kepler. However I changed creating and extending variables to just using external jars in my eclipse classpath. This was reflected in no var's in my .classpath. This corrected the problem. I was able to do a Maven update.
This issue (https://bugs.eclipse.org/394042) is fixed in m2e 1.5.0 which is available for Eclipse Kepler and Luna from this p2 repo : http://download.eclipse.org/technology/m2e/releases/1.5 If you also use m2e-wtp, you'll need to install m2e-wtp 1.1.0 as well : http://download.eclipse.org/m2e-wtp/releases/luna/1.1
Upgrading from Kepler to Luna worked for me. I had just added some components for Java 1.8 support. It seems that they where not as compatible as I would like or that I mixed the wrong ones. It really caused a lot of problems. Trying to update the system reported errors as they couldn't fulfill some dependencies. Maven upgrades didn't work. Tried a lot of things. So, if there is no reason to avoid the upgrade just add the luna repository to avalilable software sites (Luna http://download.eclipse.org/releases/luna/ ) and "check for updates". It is better to have all the components with the same version and there are some nice new features.
I tried all the steps mentioned here and on similar questions but couldn't solve this problem. I could neither solve problem nor update my m2eclipse. So I installed Eclipse Luna and it solved my problem... though it mean that I had to spend about 45 min to configure all the environment in my workspace.
Try mvn clean install eclipse:eclipse -Dwtpversion=2.0 command on DOS command prompt. Suggesting you because , It worked for me!!
I'm using Eclipse 4.3.2 (Kepler) with M2E 1.4.x and felt over this problem several times! In my case the "mvn eclipse:eclipse" command also generates Checkstyle, PMD and Findbugs configuration so "mvn eclipse:clean" does not help me because it drops all those config files again. The best solution for me was to delete all ".classpath" files: find . -name ".classpath" -delete and import the project into eclipse afterwards.
Before importing the project, it should be converted into eclipse project mvn eclipse: eclipse Then i found the following error. An internal error occurred during: "Importing Maven projects".Unsupported IClasspathEntry kind=4 Where is the value kind = "var" that M2E does not recognize and therefore throws the error. Now type this. mvn eclipse: clean Now refresh the project in eclipse or re-import.
maven plugin for eclipse, proxy issue
I use m2eclipse to integrate Eclipse (Indigo) and Maven. I also use a proxy, so I have a Settings.xml with the correct host and port. I've configured the LAN Settings of the OS too, so Eclipse is configured in the same way (Native mode). Finally, I have put an external maven as the Eclipse installation (Maven 2.2.1) . Once I did that, I import from Eclipse a Maven project. When I do "mvn install" the artifacts are downloaded, and I get the "Build Succesfull". However, the project marks an error. The error type is different if is a project with dependencies (pom dependencies) or a simple project. For example, in a simple project the error is "Could not calculate build plan: connection timed out". In a complex project doesn't read some artifacts, which are in the repository. I think the problem is the plugin and the proxy because in the console appears when eclipse starts, "Unable to update index for central http://repo1.maven.org/maven2/". Any idea? Thank you for your help Ángel
Since your build is working fine I believe your setting.xml is maven installation folder is working fine. So try to change the maven setting in eclipse as shown below and refer the same setting.xml that is there in the maven folder configuration.
Not a very helpful answer, but I ran into the same problem. m2eclipse didn't seem to handle proxies (either eclipse or .settings) very well. My workaround at the time was to always have a command line handy to pull in new dependencies.
I had the same problem with the Maven error: Could not calculate build plan: connection timed out What finally fixed it was a complete Clean and Rebuild: Project > Clean... (x) Clean all projects (x) Build the entire workspace
