How do you integrate Robolectric, Maven, ActionBarSherlock (and preferably + IntelliJ) into an Android project?

Question

I've been banging my head against a wall for some time trying to get maven, robolectric, actionbar sherlock, and intellij, to all play nicely. I've given up on building with intellij for now and am focusing on maven.

I have an app with an action bar when I skip the tests in the maven build (which tells me I'm good to go on the ActionBar integration front). The IntelliJ build fails on ManifestParsingTest.java complaining that it doesn't know where junit is (among other issues).

Robolectric integration

I already had Robolectric running successfully in the project. I copied the files from Jake Wharton's gist into src/test/java/com/blah/blah/support/ (except ShadowSherlockFragmentActivity.java which lives in src/test/java/com/blah/blah/support/shadows/) and put this line in the constructor for my custom test runner (lives in support folder):

ActionBarSherlock.registerImplementation(ActionBarSherlockRobolectric.class);

mvn errors

I'm running into these build errors (IntelliJ also has red squigglies for the same stuff):

Is there some project config I'm missing?

Answer 1

At Square, to support this use case we use a modified version of Robolectric. We are working with Pivotal to get us off of using a fork and the necessary changes upstream into the main repository. The changes required are hooks into the resource loading system. These methods are currently private which is the cause of the compilation failures that you are seeing.

Pivotal doesn't exactly make releases in any semblance of a frequent manner so if the changes do make it upstream you'll likely have to use the SNAPSHOT version for a while.

Answer 2

I could make it work.

Try this:

• move robolectric and junit dependencies to the end.

• indicate src and test path in the build tag, after finalname and before plugins.

• rebuild and run test from maven toolbar.
