Hi, Dennis, I'd suggest the following approach:
- Write a small stub that replaces Logger.getLogger(), so that a small facade is returned, which behaves like JUL, but uses the Maven logger internally. - Use the shade plugin to ensure that Logger.getLogger is redirected to your stub. That way, you don't need modifications in Cobertura upstream, but are still controlling what's being logged and how, Jochen On Tue, Nov 11, 2014 at 8:48 AM, Dennis Lundberg <denn...@apache.org> wrote: > Hi, > > I'm working on the Cobertura Maven Plugin over at Mojo, and have run > into a problem that I cannot solve. > > This plugin wraps an external tool, Cobertura, which logs stuff either > by System.out.println() or by using Java Util Logging (JUL).
