TypeNotPresentException when running android testcase with robolectric and eclipse

Question

I've the following example test case set up set up in an android test project I'm working on.

package com.whatever.test;

import static org.junit.Assert.fail;
import org.junit.Test;
import org.junit.runner.RunWith;
import com.xtremelabs.robolectric.RobolectricTestRunner;

@RunWith(RobolectricTestRunner.class)
public class SomeClassTest {

  @Test
  public void testFromJson() {
    fail("Not yet implemented");
  }

}

I did set up a junit run configuration, it runs with junit4 and I've tried both with Java 6 (mac os x default) and oracle's jdk 7.

No matter how I try I always get the following error

I'm using last android sdk (api level 17) bundled in the adt package and I'm using robolectric 1.1 as an external JAR.

I'm open to alternatives if running the tests with eclipse in that way is not the best.

Edit: I've been suggested to check that Robolectric appears before Android in the classpath, which I did. And the problem persists.

Edit 2: I've followed the suggestions in the comments, but none of them seemed to work, the error persists.
