I just updated IDEA CE to 14 and then had to update Grammar-Kit to 1.20 as a result. After doing so, my generated parser classes are now going into my primary "src" directory instead of my "gen" directory. I see that one of the recent enhancements to Grammar-Kit is auto-detection of the generated source output directory, but to me it seems to be detecting the wrong directory. Is there some way I can force it to use my "gen" directory for generated output again?
By the way, otherwise IDEA CE 14 and GK 1.20 seem to be generating a parser successfully that works as a custom language plugin in the newer version, so that's good!
