Maven pauses and does not continue with build

Question

I am calling a script located at my server using maven. Before doing this change, the build was running successfully but after introducing this change, it pauses and does not continue the build after executing my changes I made in the pom. It basically freezes.

The script consists of me looping through number of files in a folder and just getting their name. Nothing to heavy or drastic.

This is part of my POM that has my change.

I followed an answer from this as this helped my initial problem: Run remote command via ssh using Maven3

EDIT: I've noticed that sshexec hides the rest of the maven output. I've came across this but this didn't help: maven antrun ssh or scp hides the output
