Can I enable DEX verbose logging?

Question

I moved my Android IntelliJ IDEA project from one location to another. For some reason, IDEA lost all the modules and I had to re-import them.

Now when I compile, I get this DEX error:

Error:Android Dex: [MyApp] Unable to execute DX 
Error:Android Dex: [MyApp] com.android.dex.DexException: Multiple dex files define Lcom/google/common/base/FinalizableReference;

I can't figure out what the cause is, all the usual suspects of multiple JARs seems to be ok.

Is there a way to turn on verbose logging to get a better understanding on which libs are in conflict?

Answer 1

I don't know how to get better error description from DEX, but here are 2 suggestions to troubleshoot:

1. If using Android Studio, just search for the offending class FinalizableReference (include non-project classes in the search). (Use Command+N for find class or double tap Shift for "search everywhere". For eclipse: Ctrl+Shift+T? others can confirm.

2. Using the command line: jar tf mylib.jar | grep FinalizableReference will search mylib for the class. You can then use some shell for loop over the jar files (usually in libs dir). Also grep -r FinalizableReference libs/*\.jar will scan all the jars (assuming you have them in libs) and notify the ones that have a match (the duplicates).
