I was just "happily' working in Eclipse (Neon) and had multiple projects loaded, which is the way I always have worked and suddenly my files started getting red-lined with lots of errors indicating my imports weren't recognized and I looked at the referenced libraries in each project and the no longer had the forgsrc libraries. I thought that maybe Eclipse just got buggy so I restarted Eclipse and also restarted computer, but it did not help.

 

I reran gradlew setupDecompWorkspace and gradlew Eclipse and that fixed the problem. But had to run it on each project (and I've got dozens of them so it was a pain).

 

Why would the referenced libraries get screwed up on all my projects simultaneously? I understand the class path of one project getting screwed up, but all of them?

Your computer only holds one forge source per version (for obvious reasons), but I don't know what would have caused this error. That at least explains why it would mess up all of them.

Sounds to me like Gradle mucked up for some reason. As Animefan said, there is only one copy of Forge per Forge version, so if that gets deleted somehow all projects will lose access to it. Though I think that would cause single error, something like "<project> could not be built because it is missing referenced library <library>",

Okay, I guess that makes sense. It wasn't too hard to fix, but I really don't think I did anything that should have caused it but maybe some keyboard shortcut or something was inadvertently pressed.
