I am working on a very large project in IntelliJ IDEA (currently version Ultimate 2020.1.4) - with over 100,000 java files, close to 50,000 resource files, dozens of modules, several gigabytes of external libraries - you get the idea.
When I first opened the project, it took a good 30 minutes or so for IntelliJ to index the project (which I did expect). However now, as I work with the project, almost constantly IDEA shows message "Search for files to reindex" and "Reindexing" - the reindexing is running almost all the time. This makes development and especially debugging a very painful experience indeed.
I tried uninstalling and reinstalling IntelliJ; deleting the entire source tree and re-cloning the git repo - the behaviour is still there.
Any suggestions on how I can get it to stop constantly search for files to reindex?
