Brett Porter commented on MNG-4667:
-----------------------------------
I have code on a branch to do that, but that would a future thing if at all,
and it wouldn't work with existing users using the gpg plugin.
Perhaps a better approach to this is to promote the POM plugin from the sandbox
and add a goal to it to remove the BOM so it is easy for someone to run if
their project is invalid?
If that was in place, someone could potentially add a better error message to
Maven to suggest running it.
