| 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:
| org/aspectj/lang/NoAspectBoundException
|
| 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,
| Sebastian

You need to include the aspectjrt.jar probably for obfuscation step and surely for the runtime env
classpath.
