Android Studio doesnt build after update

Question

I have just updated Android Studio to build 130.729444, and my project (which built correctly before the update) has stopped to work, and Android Studio shows me the following error:

Internal error: (java.lang.AssertionError) Unexpected node Android Packaging; nodes=[Module 'MyApplication' production, Module 'MyApplicationProject' production, Module 'MyApplication' tests, Module 'MyApplicationProject' tests, Resources for 'MyApplication' production, Resources for 'MyApplicationProject' production, Resources for 'MyApplication' tests, Resources for 'MyApplicationProject' tests, Artifact 'MyApplication', Android Gradle Build Target]

Anyone know how to solve this? I've thinking about returning to old version, but I want to know if it's my problem or I'm not the only one.

Answer 1

Get same issue with IntelliJ 14 when try to add artifact. Removing .idea/artifact folder solves issue.

Answer 2

I recently filed a bug report to Google . According to the thread in the Android developer tools forum this is an issue they can´t directly explain. I think this is as good as an answer we can get untill this bug is adressed by the developers.
