we created a relatively simple plugin for Codename One support. It effectively just hides our ant build system.
However, when we try to change the classpath we get the error message: "Library 'x' not used"
And as a result we can't get code completion or anything else to work. I posted the question on SO http://stackoverflow.com/questions/21626113/adding-a-directory-path-under-intellij-12-claims-library-libraryname-is-not-us as well.
I'm somewhat at loss on why this is happening and where I should start looking?
