Description

I have deleted .class files generated from groovy script and now no more class file are generated.

I'm getting eclipse error when I clean my projet:

Which version of the groovy-all is in your plugin/lib directory? I encountered several strange errors with the last version checked into the plugin project prior the JSR-06 release. I added the JSR-06 to CVS and used that with the plugin. Although, I only used it for one day, I didn't see any of the errors I was seeing before.

The fact that the plugin is trying to generate an error marker means that there is a compilation error. The Groovy compiler doesn't generate any new .class files when there is an error. If you do a clean, and there is only one error, no .class files get generated.

The only time I've a stack trace similiar to yours is with a specific version of the plugin and a groovy-all snapshot prior to JSR 06. With what's in CVS for at least the last week or so, I've haven't seen that error. It doesn't mean it's still not there, but

At this point, I think what might be helpful is to try replacing your Groovy plugin with the latest from CVS and see if the problem persists. If it does, please zip up your workspace, if there's nothing proprietary in it, and sent it to me and I'll take a look at it.

I just applied a patch for issue 1414. I think this might fix the NPE that you were seeing. Can you download the latest plugin from CVS and test it? Thanks.
