Hi,
FYI, I whipped up a small plugin that automatically update out-of-date project configuration, under our JBoss Tools Playground repo [1].
I'm not sure if it's completely safe to use. There's no preference to (de)activate it -yet-. The plugin is set to start on workspace startup for now, which isn't ideal, but if you deactivate it from Preferences > Startup and Shutdown and restart the workspace, it should be inactive.
It's, most probably, sub-optimally implemented, but it worked on the small set of projects I tried.
p2 site to install it from is at [2]. Feel free to try it and give some feedback. Then we can discuss what to do with it, wrt [3].
