GitHub user todor opened a pull request:
https://github.com/apache/maven-plugins/pull/39
Support for purging output directory before unpacking. If a new version ...
...of the artifact is available and part of the contents is deleted in this
new version, it should be deleted after unpacking to avoid undesired side
effects. E.g. if we deploy large test data (let's say > 1 GB ) we would like to
unpack it only if there is a change in the data but anything deleted from the
previous version should be removed too. purgingOutputDirectory provides this
capability. The consumer should be careful to configure purging in a
non-conflicting way which can end up with deleting data that won't be
unpacked.(If two artifacts have the same output folder and one of them needs
processing and purges the output folder, then the other one should be unpacked
even if it is not updated)
