Comment by pekka.klarck:
zhizhong.huang, my understanding is that AutoItLibrary doesn't run on
Jython so using it with the JAR distribution isn't possible. There has
recently been promising work in the Jython project to support running C
based Python modules so at least theoretically adding Jython support to the
AutoItLibrary is possible. You may want to start a discussion about that on
the robotframework-users mailing list or submit an enhancement request to
AutoItLibrary's tracker.
