Intellij IDEA: NoClassDefError in Instrumentation test of a SherlockActivity, but working from Maven commandline

I'm trying to setup an instrumentation test for an Activity which extends SherlockActivity, it compiles (and runs) but fails with NoClassDefError exception:

junit.framework.AssertionFailedError: Exception in constructor: testPreconditions     (java.lang.NoClassDefFoundError: com.dgti.ds.activities.ChooseLocationActivity

I'm using Maven and got ActionBarSherlock as a dependency in the test project's pom.xml:

<dependency>
  <groupId>com.actionbarsherlock</groupId>
  <artifactId>actionbarsherlock</artifactId>
  <version>4.2.0</version>
  <scope>provided</scope>
  <type>apklib</type>
</dependency>

this the test case:

public class ChooseLocationActivityTest extends ActivityInstrumentationTestCase2<ChooseLocationActivity> {

    public ChooseLocationActivityTest() {
        this(ChooseLocationActivity.class);
    }

    public ChooseLocationActivityTest(Class<ChooseLocationActivity> activityClass) {
        super(activityClass);
    }

    public void setUp() throws Exception {

    }

    public void tearDown() throws Exception {

    }

    public void testPreconditions() throws Exception {

    }
}

its worth mentioning that I can successfully run other tests and also this one if I change the activity to a non-Sherlock activity.

also, building and running the test project from maven command line works and the tests are running on the emulator and passing !

how can I fix this ?

apparently the problem was with the ActioBarSherlock dependency marked as 'compile' in the test project's dependencies list. (in pom.xml its set to 'provided')

changing it to 'provided' fixed the issue.
