Many build tools write caches to hidden folders in the home directory. You can see them with ls -a. e.g. .npm, .sbt, .gradle, .cargo etc. The compilation result of the code is often in the root directory of the project, such as maven, the sbt project will be written to the target directory, and the cargo project will be written to the build directory. The cache files mentioned above cannot be scanned and cleaned by CleanMyMac.
