Hi, Thanks for the suggestions.
--no-snapshot-updates does not make a difference. I tried out the profiler and it gives me a breakdown of timings per phase, but it does not have any timings on what happened before the first phase starts, which is exactly where the slowdown occurs. Converting the job to a freestyle project in jenkins also solves the issue, but it's not really an option for us since we rely on a lot of the functionality that the maven job type offers. I guess i will have to head back to the Jenkins side then to find out what is going on. I know Jenkins is instrumenting the maven process with some extra functionality and even rewrites the pom internally before execution. Apart from that, is there any other way to get a bit more debug info out of maven during the 'scanning for projects' phase ?
