Unfortunately, it looks like the author of the plugin did not implement a MOJO that would support direct invocation, hence the plugin must be used as a part of lifecycle execution — within the <build>
section.
If you need to run tests quickly, you could try to temporarily change the <phase>
to some earlier one, for example validate
. I'm sure, though, this is not the phase the plugin intended to be run in, so you can't change this permanently.
