Dex merger problem on testcoverage with 2 modules.

[Niek Pulles]

Hi,

Any has any clue why I receive the following error on transformClassesWithDexForDailyDebug:

UNEXPECTED TOP-LEVEL EXCEPTION:

com.android.dex.DexException: Multiple dex files define Lcom/vladium/emma/rt/RT;

        at com.android.dx.merge.DexMerger.readSortableTypes(DexMerger.java:596)

We have 2 modules in Android studio, both have: "testCoverageEnabled true". 
1st module is sdk, 2nd module is app. Both have unit tests.

So module 1 is include in module 2. When I remove "testCoverageEnable true" in any of the modules it's working fine, but then I don't have any testCoverage reports for either module.

sdk gradle file: http://pastebin.com/JHYiTP5e 
app gradle file: http://pastebin.com/nG2KXjaG

It looks like it does merge the sdk module in the app module with both having jacoco, seems like to work for all other dependencies (which are duplicated in both gradle files).

Thanks in advanced.

Forgot to mention, it's with: com.android.tools.build:gradle:1.4.0-beta6 and not happening with 1.3.0, all other beta versions of 1.4.0 have other issues which make it not compilable and solved in beta6.

I'm getting this error too running tests for a library project with plugin 1.4.0-beta6. With plugin version 1.4.0-beta3 is working fine.

thanks for the report. I'll take a look at it right now.

I didn't have the time to create an example project, hopefully you have had some luck?

Xavier,

1.5.0-beta2 is working fine for me, compiling and unit test pass.

Thanks.
