There was a reason my original posting was so long...

Indeed, but we don't have any choice, do we?

The problem I was talking about in this thread is not jenkins-related.
And yes, as I said in the original posting, a git clean -fxd followed by

I don't think the built-in support works well with newest coverage 
releases and doesn't spit out xml compatible with the cobertura plugin 
for Jenkins.
