Android Studio 2.0 Gradle Bug

Question

I wasn't sure what to name the question so bear with me.

I work on two machines, my PC and my Mac. Currently I have upgraded to Android Studio 2.0 on my PC to get all the new features and it is a mess. I need help.

So what is happening is that when I try to run the app the gradle build fails. It fails with this message :

Executing tasks: [:app:clean, :app:generateDebugSources, :app:mockableAndroidJar, :app:prepareDebugUnitTestDependencies, :app:generateDebugAndroidTestSources, :app:assembleDebug]

Configuration on demand is an incubating feature.
Incremental java compilation is an incubating feature.

Here is a list of my dependencies

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.2.0'
compile 'com.google.code.gson:gson:2.5'
compile 'com.hierynomus:sshj:0.15.0'
compile 'joda-time:joda-time:2.9.1'
compile 'de.greenrobot:eventbus:2.4.0'
compile 'com.android.support:support-v4:23.2.0'
compile 'com.android.support:design:23.2.0'
}

Now the odd thing is that if I run the exact same source code on my mac its fine. So what is going on? Is this a bug with v2.0, it seems unlikely though.

If you need any more info let me know!

Thanks

Andy

Answer 1

Hey so with some help I figued out that com.hierynomous:sshj was also wanting Bouncy Castle and therefor conflicting with the caked in Android one.

Hope this helps someone in the future.
