Proguard issue Roboguice duplicate import

I am running to an issue when i run my gradle build. It seems like there are duplicate dependencies getting imported but finding it hard to debug, any suggestions would be great.

Error:Execution failed for task ':proguardDebug'.

java.io.IOException: Can't write [.......\build\intermediates\classes-proguard\debug\classes.jar] (Can't read [.......gradle\caches\modules-2\files-2.1\org.roboguice\roboguice\3.0.1\24e814f35d5cc28eaa7e9f07a50ea69deeb2b544\roboguice-3.0.1.jar(;;;;;;!META-INF/MANIFEST.MF)] (Duplicate zip entry [roboguice-3.0.1.jar:javax/inject/Inject.class]))

You can figure out what is pulling in dependencies by running this command in your project root:

./gradlew app:androidDependencies

You will get output similar to this:

Also, don't forget to check your app/libs/ folder to ensure it's empty if you're pulling everything in with Gradle.
