Scala FAQ: Where are Coursier files stored on macOS?
Solution: The files Coursier downloads are located under this directory on macOS:
~/Library/Caches/Coursier
More specifically, in early 2021 they’re located under this directory:
~/Library/Caches/Coursier/v1
In a related note, this is my current JAVA_HOME, via Coursier:
/Users/al/Library/Caches/Coursier/jvm/adopt@1.11.0-9/Contents/Home
See the Coursier docs for more information.
