java.lang.NoSuchMethodError: org.mockito.Mockito

In a Mockito test case, I have the line:

when(searchService.processSearch(isA(SearchQuery.class)))
   .thenReturn(new StringBuilder(searchResults));

This was giving me the following error when I ran the test case:

java.lang.NoSuchMethodError: org.mockito.Mockito.when(Ljava/lang/Object;)Lorg/mockito/stubbing/OngoingStubbing;

This test works on our continuous build server though. The issue was solved after I read Issue 106 reported on Mockito's google code site. Maven updated the mockito jar from 1.7 to 1.8.0, but left both jars in my local repository. Once I removed the 1.7 jar, the test case worked.
