Maven enforcer plugin very slow - omitted, kept explanation

Question

I updated the version of few dependencies in my project, the build got slow and it waits around 5+ minutes at the enforcer plugin. I tried to compare debug logs of previous builds which used to happen in 3 mins, compared to this which is taking 8+ minutes in total, 5+ minutes as I mentioned are stolen by the enforcer. The only significant difference I see in logs is below. No error or anything else, and also these logs move slow. hence the issue. If anyone knows what it means and how can I go pass-through this it would be of great help

omitForNearer: omitted=commons-codec:commons-codec:jar:1.10:compile kept=commons-codec:commons-codec:jar:1.10:compile

Please show full pom file best would be a link to github/gitlab project... — khmarbaise
I am not allowed to share the code, else I would have added, I know it is hard to imagine the scenario. I was trying to get some inputs or hints. I can around 800+ times similar line in the log, of course with different grouped. "omitForNearer" "kept", what is it exactly doing? — Aadam
Which version of maven-enforcer-plugin do you use? Which Maven version and which JDK version do you use? — khmarbaise
Which rules do you use? Please show at least the enforcer maven plugin configuration — khmarbaise
