I have a project run configuration that works correctly in IDEA 7.0.4 but not in 8.0m1. This is a maven webapp project, the the run configuration uses a local Tomcat app server, and has Before Launch > Run Maven goal '<appname> package' checked.
When I try to run or debug, a message appears at the bottom of the window: "All files are up-to-date" and I get a growl message: "Compilation Finished" but it does not start Tomcat. If I uncheck "Run Maven goal" or open the project in 7.0.4, things work normally.
I've reproduced this in a minimal project created from the Maven webapp archetype (attached).
I don't see messages in the log that appear relevant but I'll attach that too.
