After recently converting to Maven from Ant, run configurations that launched immediately pre-Maven take an excessive amount of time and consume an abnormal amount of resources while Eclipse prepares to launch the projects.
Eclipse shows this status message:
Verifying launch attributes...
At 57% completion, Eclipse hangs for several minutes before finally launching the run configuration. Once launched, the project runs fine and without a problem.
I found this blog article that suggested to clean the local workspace, but that did not solve the problem, especially considering the author is using Git and I am not.
I am only using the latest m2e maven plugin, with the latest version of Eclipse.
What is causing Eclipse to block when launching these run configurations, and how can I fix it?
