I'm grateful for the clean build efforts. I can also relate to the frustration when spending time on ancillary stuff.

I wanted to see if I could do 10 clean builds in a row, using commit 8b0f18fa95a87b60aab070c388d55b9825e49c6c.
I just did 'mvn clean; mvn install' ten times. Nine of the ten completed with success. Only my 4th build had trouble, with "ch.qos.logback.core.appender.FileAppenderTest". I pasted the results below.

In any case, this is a significant improvement to build stability, and it will let me move on. I also think this has great value to others who might want to contribute code to the project too. A functioning build process is needed when starting out. So for your bit of diversion I say, "Thank you".

It sounds pretty pathetic to make a big deal out of clean builds. However, getting all the tests to pass consistently has proven to be a big challenge. Frustratingly enough, none of the failures have to do anything with the "actual" logback code but with test code.

    Hi all,

    In light of recent improvements in the test suite, we had a streak
    of of 18 successive clean builds by Jenkins. It ended with a failure in
    ch.qos.logback.classic.net
    <http://ch.qos.logback.classic.net>.__SMTPAppender_GreenTest.__testMultipleTo

    [1].

    In any case, we are making progress.
