mvn install deploy does not work with 3.2.1 but worked with 3.2.0

Hi there,

I've got an archetype build that used to work fine with 3.2.0 but fails with 3.2.1.

The problem with 3.2.1 is that all the files in target/test-classes/projects/it-basic/project/basic-project do exist but are all empty (0 bytes).

The build is run with mvn -U clean install deploy. If I run it with mvn -U clean deploy it works. Although the install goal may be superfluous, I guess there is something wrong there with version 3.2.1.

I attached the logs of a successful run and a failed one to this ticket.
