NoClassDefFoundError: com/google/common/base/Predicate when importing MonkeyRunner in Jython

Question

I want to use MonkeyRunner to generate MotionEvent (from screen touch). I have read the info on http://developer.android.com/guide/developing/tools/monkeyrunner_concepts.html.

The problem is that for this jython program:

from com.android.monkeyrunner import MonkeyRunner

if __name__ == '__main__':
   # Connects to the current device, returning a MonkeyDevice object
   device = MonkeyRunner.waitForConnection()

I get the following error when executed:

Traceback (most recent call last):
  File "C:\Documents and Settings\jjungb00\python\workspace\monkey\src\runner.py",     line 6, in <module>
    from com.android.monkeyrunner import MonkeyRunner

I have added monkeyrunner.jar from the android sdk tool/lib as an external library. I'm running on XP, with jython 2.5.2.

Any idea what to do? I guess I must add another library, but I do not know where or which.

You need to add the Google Collections library - currently renamed to Guava. Look for guavalib.jar in the android SDK directory.
