Libraries do not get added to APK anymore after up

Question

I have a rather big Android App project that is referencing several library projects. Everything was fine until i upgraded the eclipse ADT plugin to the newest version (v22). I also upgraded the SDK of course. I do not see any compile errors in eclipse, but when i run the project on the phone i get a NoClassDefFoundError.

java.lang.NoClassDefFoundError: org.acra.ACRA
....

The arca library is included in one of the referenced library project (in the libs folder) and i can see it in the "Android Private Libraries" in the package explorer, also as i said, no compile errors. The project runs fine on everyone else's computer that did not upgrade ADT.

I have already tried a whole bunch of stuff including but not limited to:

• re-install the android SDK
• download a fresh ADT bundle
• delete all my code an get it again from git
• copy the library in question to the app project
• comment out the code that uses this library - i just get the same error for the next library

all without any success, so i'm getting really desperate here.

I would be really happy if anyone could give me a hint on how to solve that problem.

I had the similar issue and my answer is slightly different from CommonsWare's. Here is my screenshot:

After checking the libs back in my build started to work again.
