 When debugging vert.x applications inside Eclipse, I could get breakpoints to work when starting a unit test in Eclipse with Debug as Junit, but for some reason I couldn't put any breakpoints when running the complete application with a maven task (even though this supports Debug as as well). When debugging vert.x applications inside Eclipse, I could get breakpoints to work when starting a unit test in Eclipse with Debug as Junit, but for some reason I couldn't put any breakpoints when running the complete application with a maven task (even though this supports Debug as as well).
