In the section Cobertura plugin and Maven3 of "Maven2 → Maven3 migration - real life example" article I made a mistake that resulted in reporting a bug that does not exist.
Both goals instrument and check must never be in the same execution because check depends on instrument and calls it itself. So, in my example goal instrument was executed twice every time and it cause a lot of problems - many of them are still magic for me e.g. compilation error saying that ...HasBeenInstrumented class cannot be identified blah, blah, blah, even though "buggy" source code was untouched and did not use this Cobertura class. Anyway MCOBERTURA-155 is a non-issue.
should be changed to:package clean check
clean clean clean package package check
