Demo project reproducing the problem

I tried to help that guy on http://stackoverflow.com/questions/26800286/duplicate-entry-in-aspectj/26806352. As he did not even post a full callstack, I tried to reproduce the problem and was successful. I am attaching a ZIP file containing three Eclipse projects as follows:

SO_AJ_DuplicateZipEntry_AspectJ: aspect DemoAspect -> aspect.jar

SO_AJ_DuplicateZipEntry_Lib: Java classes Application, Demo -> lib.jar

SO_AJ_DuplicateZipEntry_Java: Java class Application -> bin/

Please note that class Application occurs twice.

Now if you enter the SO_AJ_DuplicateZipEntry_Java project directory and run build.bat (or build.sh) containing this command:

ajc -cp "%CLASSPATH%" -inpath ..\SO_AJ_DuplicateZipEntry_Lib\lib.jar;bin -aspectpath ..\SO_AJ_DuplicateZipEntry_AspectJ\aspect.jar -outjar out.jar

there is an error as follows (also contained in build.log inside the ZIP archive):


(...)\SO_AJ_DuplicateZipEntry_Java\bin\Application.class [error] unable to write compilation result
