The directory used by IntelliJ IDEA to store settings and caches.If you’re experiencing poor build performance, please follow the instructions of your anti-virus product to exclude the following directories from real-time scanning: If you’re using a different anti-virus product, you still may be impacted by the problem, but there is no possibility to detect or correct this automatically. For every folder shown in the notification, press the + button, select “Folder” from the menu, and select the folder.Scroll down if needed, and then click on “Add or remove exclusions”.Click on “Manage settings” under “Virus & threat protection settings”.If you prefer to perform the necessary configuration manually, you can do so by following these steps: The IDE offers you a possibility to exclude those directories from scanning automatically (this feature is available in 2019.2+ IDE versions). If you’re using Windows Defender, the IDE automatically checks whether you have real-time scanning enabled, and whether the scanning is configured to process directories where the IDE writes a lot of files. If your antivirus software has real-time scanning enabled, the antivirus can force the build process to halt each time a file is created while the antivirus scans that file. When you run a build in the IDE, many class files are created on your computer.

Some antivirus software can interfere with the IDE build process, causing builds to run dramatically slower.
