Hi,
I really have some big problems with writing an ant build file for an
application using an AspectJ aspect. The application is a J2ME project and
that's why I need an abfuscator. I am using proguard as obfuscator and since
3 days I am now trying to write an ant file for building my project. Cause I
am relative new to writing ant-files by myself, maybe the solution of the
problem is easy, but at the moment I don't see any way to solve my
problem...
So the problem is that I don't know which jars to include in the obfuscation
process, cause when I try to start my application I always get an error that
he cannon find class org/aspectj/lang/NoAspectBoundException. I tried
several things, like including aspectjtools.jar and aspectjrt.jar in the
obfuscation-process, but none has any positive results on building... I only
get millions of warnings, when I do this. So here is my actual build-file (I
am already using as compiler the ajc-compiler; as ant-task I am using iajc):
build.xml:

So the j2me preverifier tells me that he couldn't find the class:

I really don't know how to solve the problem, so for any hints I would be
sooooo thankful and happy, cause I am really getting depressed with this.
Thanks in advance,
