Use mvnDebug instead of mvn at the command line. This will start it in debug mode and you can attach to it from IDEA. Otherwise Wicket quickstart comes with src/test/java/**/Start.java. Run this class as normal Java application with main(String[]). From the context menu in the .java file choose "Debug 'Start.main()'"
