Mockito + Dexmaker on Android

Question

I am trying to use Mockito in my Android project. I have found very nice tutorial that deals with it: http://www.paulbutcher.com/2012/05/mockito-on-android-step-by-step/

Basically it uses new version of Mockito + Dexmaker and everything works as expected.
However, when I try to mock some Android specific object i.e:

Context context = mock(Context.class);

I receive this exception:

java.lang.IllegalArgumentException: 
    dexcache == null (and no default could be found; 
    consider setting the 'dexmaker.dexcache' system property)
at com.google.dexmaker.DexMaker.generateAndLoad(DexMaker.java:359)
at com.google.dexmaker.stock.ProxyBuilder.buildProxyClass(ProxyBuilder.java:252)
at com.google.dexmaker.mockito.DexmakerMockMaker.createMock(DexmakerMockMaker.java:54)
at org.mockito.internal.util.MockUtil.createMock(MockUtil.java:26)

Any idea how to fix it?

From @rjath's comment of @MrChaz's answer, this works better for me:

System.setProperty(
    "dexmaker.dexcache",
    getInstrumentation().getTargetContext().getCacheDir().getPath());

I put it in my setUp() method.
