Gradle aborts compilation for no reason during unit testing

I want to run Unit test with this code:

import com.twitter.sdk.android.core.Callback;
import com.twitter.sdk.android.core.Result;
import com.twitter.sdk.android.core.TwitterException;
import com.twitter.sdk.android.core.models.Tweet;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.ArgumentCaptor;
import org.mockito.Captor;
import org.mockito.Mock;
import org.mockito.MockitoAnnotations;
import org.robolectric.RobolectricGradleTestRunner;

import java.util.List;

import kravtsov.evgeny.clean.entities.Article;
import kravtsov.evgeny.clean.repository.TweetRepository;

import static org.mockito.Mockito.verify;

@RunWith(RobolectricGradleTestRunner.class)
public class GetTopArticlesTest {
    private static final TwitterException ANY_EXCEPTION = new TwitterException("Random exception");
    private static final long TWEET_ID = 582295217115541505L;

    private GetTopArticlesImpl useCase;
    @Mock
    private TweetRepository model;
    @Mock
    private Callback<List<Article>> callback;
    @Captor
    private ArgumentCaptor<Callback> callbackArgumentCaptor;

    @Captor
    private ArgumentCaptor<Result<List<Article>>> articleArgumentCaptor;

    @Before
    public void setUp() throws Exception {
        MockitoAnnotations.initMocks(this);
        useCase = new GetTopArticlesImpl(model);
    }

    @Test
    public void testGetMostRtArticles_failure() throws Exception {
        useCase.execute(callback);
        verify(model).getTimeline(callbackArgumentCaptor.capture());
        Callback<List<Tweet>> callbackApi = callbackArgumentCaptor.getValue();
        callbackApi.failure(ANY_EXCEPTION);
        verify(callback).failure(ANY_EXCEPTION);
    }
}

After starting this test (about 20 secs) Gradle aborts compilation with no exuses:

Information:Gradle: Executing tasks: [:app:generateDebugSources, :app:prepareDebugUnitTestDependencies, :app:mockableAndroidJar, :app:assembleDebug, :app:assembleDebugUnitTest]

Information:28.10.2015 14:24 - Compilation aborted

Simple googling didn't give me any clues. Can someone explain me this problem, please?

Here is build.gradle (module:app) :
