Re: ANT - Checkstyle with custom check

I had a similar issue for some time. The target would work only on my
machine.

I had to fix and try out some of the following to get my target to work:

Adding the custom checkstyle jar to java's extensions java\lib\ext
Using ant 1.7
Making sure there isn't some other jar for checkstyle library being used
from some other location

Thanks
