Versions
WorldEdit version: 7.2.0-beta-2
Platform version: 1.16.1, git-Paper-74

Describe the bug
On Windows, regen "fails" due to being unable to cleanup the temporary world gen.

To Reproduce

  1. Use Windows
  2. //regen

Expected behavior
No errors should be propagated out.

Additional context
There's a solution that Gradle has for this. I'll be looking at that and seeing if we can port it.

Edit: stacktrace:

Leaving this here for later:

    private boolean tryHardToDelete(File file) {
        if (deleteFile(file)) {
            return true;
        }

        // This is copied from Ant (see org.apache.tools.ant.util.FileUtils.tryHardToDelete).
        // It mentions that there is a bug in the Windows JDK implementations that this is a valid
        // workaround for. I've been unable to find a definitive reference to this bug.
        // The thinking is that if this is good enough for Ant, it's good enough for us.
        if (runGcOnFailedDelete) {
            System.gc();
        }
        try {
            Thread.sleep(DELETE_RETRY_SLEEP_MILLIS);
        } catch (InterruptedException ex) {
            Thread.currentThread().interrupt();
        }

        return deleteFile(file);
    }
