Returns the logger that has been injected into this mojo. If no logger has been setup yet, a SystemStreamLog logger will be created and returned.

Note: The logger returned by this method must not be cached in an instance field during the construction of the mojo. This would cause the mojo to use a wrongly configured default logger when being run by Maven. The proper logger gets injected by the Plexus container after the mojo has been constructed. Therefore, simply call this method directly whenever you need the logger, it is fast enough and needs no caching.
