Can you share your gradle file as well? The questions I'd want to answer by
looking at it are:
- When you run your test module, what gradle task are you using?
- When you generate your coverage, are you doing it after a successful test
run?
- From module 1 / 2, are you calling sourceSets.androidTest.setRoot() and
using the test module?
- Are you using the builtin Jacoco from Android plugin, or trying to run
your own config of Jacoco plugin?
- When you say empty report, what do you mean? Is there an actual
index.html and it just doesn't have any classes listed?
>From my experience, it is very hard to customize the Jacoco that comes with
Android plugin. You should be able to add configuration options to
android.jacoco{}, but the only thing supported is 'version'. This is
because we have a special version of JacocoExtension that is very limited:
com.android.build.gradle.internal.coverage. Long story short, you should
probably be rolling your own jacoco task. :)
