As reported by @rgoers on [the mailing list](https://lists.apache.org/thread/dbbt5j3q8ry30q6tqcy1v422nm6q597t), the Log4j Maven Transform plugin can fail if if runs multiple times:

> I built and ran my test project and it ran fine. However, the first time I ran my project build it failed as below. I ran it several more times and it worked the second time, failed the same way the third time and then worked the few times I ran it again after that.
