I modified community source. Now I want to use that modified version of community instead of the one from Jetbrains . The only way I know how to do this is to launch the community from JB, open my modified version as a project and then push run. There has to be a better way but I am not sure what it might be. Does building community create a nice executable with a nice idea.exe.vmoptions file also ? It doesn't seem to be the case, at least as far as I can tell. What do other people do?
