> The problem is in {{CoberturaInstrumentMojo.java}} line 121, namely after the
> second run of the plugin {{outputDirectory}} is the same as
> {{instrumentedDirectory}} because somehow
> {{getProject().getBuild().getOutputDirectory()}} gets changed magically.
> I have a dirty workaround that works for me (see attached patch)
> Could you please fix it properly (if possible)? Or if you know what's wrong I
> can do the fix - just explain me what's wrong (I'm not an expert in Maven
> lifecycle, yet).
