Android Studio 1.0 RC 4 Build Error

Question

I did my best to import a project from intelij and I get this really long error that I can't make any sense of. I tried doing a "invalidate and restart" and got the same error. I don't know what if any of my build files are relevant to this error, if you have a suggestion let me know and I will update with it.

Error:Execution failed for task ':app:dexDebug'.

changing build tools to 21.1.1 causes this error:

Error:Execution failed for task ':app:dexDebug'.

Answer 1

com.android.dex.DexException: Multiple dex files define
com/google/analytics/tracking/android/AnalyticsClient

The error is due to multiple dependencies (jars, aars, or projects) containing the Google Analytics library. This could be because:

1. Sometimes the intermediate build files get in a weird/bad state, particularly if you're adjusting dependencies or changing your build tools without cleaning. Go to Build->clean project, or run `./gradlew clean', then try to build again.
2. You're referencing the same library twice (for example you're including the Google Analytics jar, AND you're using the gradle/maven artifact). Remove one or the other.
3. Least likely - two different libraries/dependencies actually contain Google Analytics. You can manually inspect the jar/aar files to see what packages they contain either by using a utility like JD-GUI, or more easily you can look in Android Studio at your project's build folder (typically build/intermediates) to see if you have duplicate entries for the package referenced in the error you posted.

If #1 doesn't work, I'd start by auditing all of your project's dependencies. In general I stay away from the project structure dialog and just manually edit the .gradle files. I suggest adding redacted version of your .gradle file(s) to your question.
