Hey, got the same problem. Do you have already solved it?
Greetings.

I had this same problem, and I was able to work around it by closing my IDE (VS code) and re-running mvn install. It is likely caused by some process using/looking at that directory, and causing the delete to fail.
When I use Eclipse, this doesn't occur, likely because I don't have the gbp folder loaded as a maven project
