Run as Groovy Script stopped working after installing newest snapshot plugin

[kovax]

After I have updated to the new snapshot release I get the exception bellow whenever I try to run a groovy script:
Caught: java.lang.ExceptionInInitializerError
java.lang.ExceptionInInitializerError
Caused by: groovy.lang.GroovyRuntimeException: Conflicting module versions. Module [groovy-all is loaded in version 2.4.7 and you are trying to load version 2.4.8

I do not have any dependencies which use groovy 2.4.7, so do not understand why I get this error. So I have checked the generated launch configuration and it contains these lines which I believe wrong:

<listEntry value="/home/dev/.m2/repository/org/spockframework/spock-core/1.0-groovy-2.4/spock-core-1.0-groovy-2.4.jar"/>
<listEntry value="/home/dev/.m2/repository/org/codehaus/groovy/groovy-all/2.4.7/groovy-all-2.4.7.jar"/>

Unfortunately even if I remove those lines I get the same error.

My environment:
Eclipse Version: Neon.2 Release (4.6.2)
Build id: 20161208-0600
Groovy Eclipse Plugin: 2.9.2.xx-201701160312-e46

Have you restarted Eclipse after updating to the latest snapshot? Do you have a Maven project? If your project is bringing in Spock, it is likely bringing in groovy-all. You can add an excludes or remove Groovy from your .classpath.

I have restarted eclipse, of course, and I use maven. The actual project does not use spock, only a dependent one as a test dependency.

[eric-milles]

If you do not need Spock or its dependencies, you can add an exclusion to your project's dependency listing for that project.

I see now. This is very confusing that maven separates test dependencies but eclipse doe not. Thanks for the help.

That is a longstanding issue for Eclipse. Each project has one and only one classpath. I have used Checkstyle to enforce that main sources do not pull in classes intended for tests, but that is not a complete solution. And that does nothing for your particular case.
