jMonkey project fails to build after adding ksoap-android-assembly?

Question

I want to use SOAP in jMonkey3 Engine to transfer files to server. ksoap-android-assembly-3.3 is a free library for using SOAP on android without any hassles. However when I added a ksoap jar file in my jMonkey project, the android build failed in a DexException. I have tried everything including creating a fresh project but the error persists. The project builds without any error as soon as I remove the jar file. I have added the build output below. The build process for desktop jar application works fine and ksoap library also works flawlessly. Kindly help.

solution is to recompile the class from source, using an up-to-date compiler
and without specifying any “-target” type options. The consequence of ignoring
this warning is that reflective operations on this class will incorrectly
indicate that it is *not* an inner class.

Answer 1

One reason for a DexException is adding a jar library more than once in the build process. Your jMonkey project possibly includes nifty libraries which already has xmlpull library included. You must remove the library from either of the two jars. You can use winrar to edit a jar and manually delete the libraries compiled byte code files.
