I have a gradle project with a submodule. The submodule has some extensions, and it worked fine for several years. For some reason, my project no longer recognizes the extensions, even though afaik I haven't changed anything. The project still compiles fine with gradle, just the IDE doesn't recognize the extensions anymore (or actually anything from that module it seems). I tried to clear caches already, run a gradle clean & deleting the build folders manually, but this didn't fix anything. Is this a commmon problem with a fix available?
