In Mill, where we use Zinc to compile Java and Scala sources, we recently tried to find the source for some left-over opened files, which produce issues for processes on Windows. We analyzed a specific compile run with https://github.com/jenkinsci/lib-file-leak-detector and found left over opened files (com-lihaoyi/mill#1939 (comment)). Non of them were directly opened by Mill but sbt/zinc instead, so I though, I report it here. I hope, you find it useful.

In the Details, you can find the stacktraces of the opened files:

The opened file is always C:\projects\sake\mill\out\main\moduledefs\jar.dest\out.jar, which is a locally built compiler plugin. It is subseqently used in other build targets, so my suspicion is, that zinc is not properly closing such compiler plugin resources. This is probably a rather rare situation, so it could be also an older issue which went unnoticed for a very long time.
