I just created a new project in Android Studio and want to add the UserVoice Java SDK as a dependency.

I'm adding the line compile 'com.uservoice:uservoice-java:0.0.2' to the app build.gradle file in the dependencies block.

When I try to build it will fail the build with 

Output:
    UNEXPECTED TOP-LEVEL EXCEPTION:
    com.android.dex.DexException: Multiple dex files define Lorg/apache/commons/collections/Buffer;
        at com.android.dx.merge.DexMerger.readSortableTypes(DexMerger.java:594)
        at com.android.dx.merge.DexMerger.getSortedTypes(DexMerger.java:552)

        at com.android.dx.command.dexer.Main.runMonoDex(Main.java:287)
        at com.android.dx.command.dexer.Main.run(Main.java:230)
        at com.android.dx.command.dexer.Main.main(Main.java:199)
        at com.android.dx.command.Main.main(Main.java:103)

At this point I have not modified the project in any way. Is there any way to exclude the offending dependencies and getting the UserVoice SDK to work?

Thanks!

The above didn't work for me, what was needed was to exclude the commons-collection dependency from uservoice.

compile('com.uservoice:uservoice-java:0.0.2'){
    exclude group: 'commons-collections'
}

This along with the following allowed it to play nice with gradle:

packagingOptions {
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE.txt'
}

I managed to get this working finally. What I did was add 

dexOptions {
   preDexLibraries = false
}

to the build.gradle android block. This was suggested here

I had to also add 

packagingOptions {
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE.txt'
}

to the same block.
