Yes it works. If you're going to muck with permissions to disallow changes
by the creating user (like some HDFS test do), then the deletion attempt will
fail and JUnit will not notice. However, in that case maven clean would fail as
well.
If you're going to rely on maven clean instead, then you should be getting
the location to write to from maven rather than hard-coding 'target' in the
working directory.
