Gradle second build fails after modifying styles.xml

I've migrated my project to use Gradle (using the old Android project structure). Recently I have upgraded Android Studio to v0.2, which forced me to use android gradle plugin v0.5. I'm able to build my project using any of the flavours I have defined, either on debug/release. Something goes wrong for me using the following scenario: - Execute gradlew clean - Execute gradlew assembleTestenvDebug - Gradle output at this point: BUILD SUCCESSFUL - Modify any value in styles.xml file - Execute gradlew assembleTestenvDebug (again) - Gradle output at this point: /Users/myuser/Project/src/com/namespace/project/views/SomeCustomView.java:60: error: cannot find symbol mSize = arr.getInt(R.styleable.SomeCustomView_some_custom_styleable, 0); Gradle now complains on every custom xml attribute I have declared in attrs.xml. This is driving me nuts as I have to clean & rebuild my project every single time I modify styles.xml PLEASE help me out. Thanks! My project structure: ``` - Project - . AndroidManifest.xml - . assets/ - . build/ - . build.gradle - . gen/ - . gradle/ - . gradle.properties - . gradlew - . libs (includes .jar files) - . modules - . . library_projectA - . .
