Android : Program type already present: com.google.common.base.FinalizableReferencequeue

Question

Getting the following error during my gradle build :

Program type already present: com.google.common.base.FinalizableReferencequeue

I understand there to be some solutions on the site for similar such errors. But they don't work for me + they don't help me search the root cause of the error. Can someone please help with some pointers ??

App level gradle file:

Answer 1

The root cause is that 2 libraries are using the same dependencies.

This often occurs when a library embedded another library (such as a fat jar) but you also declare it as a dependency (i.e. via the word compile)

In your case, you have 2 (or more) libraries using com.google.common.base.FinalizableReferencequeue which, after a short googling, correspond to Guava, and is one of your dependencies.

An easy solution would be to remove the line compile 'com.google.guava:guava:19.0'.

But if you want to know how to fix your problem, you can run the dependencies task for your app. Here app refers to the name of the module under the project.

// run gradlew which is on your root project.

// linux / osx
./gradlew app:dependencies

// windows
gradlew app:dependencies

This will print all the configuration and its dependencies. To narrow down, you can focus on only one build by adding for example --configuration debugCompileClasspath or with a flavor named myFlavor --configuration myFlavorDebugCompileClasspath (case sensitive).

You should now be able to see which other libraries is using guava and exclude it like :

compile(<dependency_path>) { //works also with project(<proj_name>)
    exclude group: "com.google.guava", module: "guava" 
}

(see more about exclude)
