Android aar's have stopped building with extractDebugAnnotations com/intellij/psi/PsiJavaFile android

Question

My build have recently stopped working for an open source gradle/android project. They've been working just fine until today (Oct 10 2016). I run a build matrix across multiple versions (on travis) of gradle and the gradle android plugin. Essentially, it's now failing on gradle 3.0 and 3, both with the gradle android 2.2.0 plugin. Other versions using different android plugins are ok. It's only the 2.2.0 plugin that's failing.

The part that baffles me is the error message

Again this is on an Android Archive (AAR) project. I've searched and can't find much on that class. It's not referenced anywhere in my code. My best guess is that google changed a support library or something that broke something. I'm also building from the command line via travis. I have no idea where the intellij stuff is coming from.

Answer 1

fixed by clearing the cache with:

rm -rf ~/.gradle/caches/

Answer 2

This has beed fixed according to https://code.google.com/p/android/issues/detail?id=224910 . You can rebuild your project with gradle command line after clear gracle cache locally (rm -rf ~/.gradle/caches/)

Also , you need do same operation on your CI agent .

Answer 3

I just faced the same issue. The problem in my project was an empty IntDef. If clearing gradle cache doesn't work, check if you don't have empty Def in your code, and remove them.

@IntDef({}) or @StringDef({}) ...
