问题
I'm trying to use the new multidex option but I get the following error:
Execution failed for task ':packageAll[Variant]TestClassesForMultiDex'.
> java.util.zip.ZipException: duplicate entry: android/support/multidex/BuildConfig.class
I've been able to discover the issue only happens when running the connectedAndroidTests task, and not when simply building the project (build).
回答1:
There's an issue for this, and it's resolved in multi-dex library 1.0.1, see: Duplicate BuildConfig classes when using multidex test support
Try:
compile 'com.android.support:multidex:1.0.1'
androidTestCompile 'com.android.support:multidex-instrumentation:1.0.1'

The last section of this specify that
Note: Use of multidex for creating a test APK requires extra setup.
This is probably the reason.
