It has not been an issue with Eclipse. I wonder if it will be for IntelliJ?
Eclipse cares about the generated sources only when we step into them.
Otherwise, Eclipse completely ignores the zillions of old generated files that
might be lying around. And, since we generate a new copy of the file each time
we generate it, the new copy will replace the old one. Even if Eclipse had the
old file open from a previous session, it will replace the old one with the new
one once Eclipse switches to that window.
Again, I need to look into IntelliJ to see if a more elaborate solution is
needed for that tool.
I like your suggestion to document this. Once all this is committed, I'll
submit a JIRA to add documentation about how to use this, along with the
IntelliJ issues, to the Developer Information page on the Drill web site.
