I've got a legacy codebase that I'd like to add a full set of checkstyle checks to so that going forward the code codebase changes will comply to the checks.
I understand I'll have to put all the existing failures into a supressions.xml file. Is there a way to generate the supressions.xml file from the existing checkstyle failures report?
There is now. Here is how to make Checkstyle run full throttle on a Legacy code base: http://juliangamble.com/blog/2012/03/10/running-checkstyle-at-full-throttle-on-a-legacy-codebase/
(If you've got a problem that an open source tool doesn't solve - fix it yourself!)
