Recently I started to get an error when I try to clean/build some plain Eclipse Groovy projects or just try to change a Groovy source in them. I was not able to fix it and I can't understand what is wrong. Fortunately, usually those projects are test projects, yet this is annoying and the only workaround I found was to delete those projects and recreate them from scratch.
This is the modal dialog that is shown when I issue a "Clean project" action:
And this is the what gets printed to the error log:

The error seems to suggest there's a problem in the project setup with regards to Groovy libraries, but the "Groovy libraries" classpath container is there (with groovy-2.5.11-indy.jar, groovy-test-2.5.11-indy.jar and ivy-2.4.0.jar), even "Groovy DSL support" container is there (although I don't use DSL support) and, most importantly, I did not manually change anything on that project that may justify some kind of project "corruption".
