Execution failed for task ':app:dexDebug'

[andrea-caselli]

I just added the library to dependencies.

dependencies
{
    compile 'io.jsonwebtoken:jjwt:0.6.0'
}

When i tried to ran the application, I got the following

Error:Execution failed for task ':app:dexDebug'.
com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.8.0_60\bin\java.exe'' finished with non-zero exit value 2

I've googled around for a while but can't figure this out, so any help would be awesome

Are you sure that's the only change you made in your Gradle file? The error message does not indicate anything about JJWT - unfortunately without more information that points to something in JJWT, I can't really help.

Do you have a sample project that can be used that demonstrates the problem is with JJWT? If not, we'll likely close this issue in due time.

I may have solution to this issue (though it is not JJWT fault). I had exactly same problem and I managed to trace it to using:

compile "com.google.android.gms:play-services:8.3.0"

INSTEAD:

compile "com.google.android.gms:play-services-gcm:8.3.0"

After cutting from all services to particular service problem has been resolved.
