java.lang.NoClassDefFoundError: org/eclipse/jdt/groovy/search/TypeInferencingVisitorWithRequestor$1Helper

[robertsmieja]

I've been banging my head against this issue for sometime. I've built a custom distribution of Eclipse, that is essentially GGTS + some extra plugins, and this error message is popping up constantly. I've checked the org.eclipse.jdt.groovy.core jar manually, and the .class file is there.

I'm referencing the Groovy-Eclipse plugin by using the following XML:
<plugin id="org.codehaus.groovy.eclipse" download-size="0" install-size="0" version="0.0.0"/>

This issue may end up being related to how the Groovy-Eclipse plugin is being installed in the custom distribution.

We are currently using Groovy 1.8 and Grails 2.1.5

[robertsmieja]

I noticed there is a "Non-Locking ClassLoader" bundled. Could that be the reason why the ClassDef for TypeInferencingVisitorWithRequestor$1Helper is not being found, even though it's adjacent to TypeInferencingVisitorWithRequestor?

[robertsmieja]

Does anyone have any idea why this is happening? We're also encountering the issue now on Eclipse Neon.1 (4.6.1)

Thanks in advance

[eric-milles]

Not sure what revision of Groovy-Eclipse you are picking up. But I have found support for 1.8 is likely not there in 2.9.2.

[eric-milles]

I thought I saw a set of commits to fix Groovy 1.8 support, but I can't find it at the moment. If that gets in, I could update Groovy to 1.8.9 and further certify the current state of support for it.

[robertsmieja]

What's the reason for closing this issue? I'm still having the issue, it hasn't been resolved.

[eric-milles]

Have you tried the latest 2.9.2 snapshot? Should be fixed.

[robertsmieja]

Ok, sounds good. I was able to give it a quick look through and it looks like it was fixed. Thanks!
