Subject Re: searching help for: class org/apache/tools/ant/taskdefs/compilers/DefaultCompilerAdapter can not be found
Date Mon, 05 Nov 2007 11:52:23 GMT

Hi Peter and all!

when i run this it doesn't work. there is the error:

A class needed by class org.aspectj.tools.ant.taskdefs.Ajc10 cannot be
found: org/apache/tools/ant/taskdefs/MatchingTask

but the class MatchingTask is in ant.jar which is on the classpath and
quoted directly.

could it be that i make some mistake in setting the classpath within
build.xml

again I append my build.xml

hope that someone could help...
