com.android.dex.DexException: Multiple dex files define

Question

I am using Android Studio 0.4.2. Opened project from a friend who is using 0.3.2. Tried to compile but got exception.

Execution failed for task \':JuiceTV:d         


        

Answer 1

Having multiDex disabled and incremental in dexOptions enabled will also cause this issue.

defaultConfig {
    multiDexEnabled = false
 }
dexOptions {
    javaMaxHeapSize "4g"
    incremental true
}
