slachiewicz opened a new pull request, #13717: URL: https://github.com/apache/maven/pull/13717
Fixes #13716. `mvn.cmd` now creates its `jvm.config` argfile and its `mvn -v` settings dump inside a directory made by a new `:mkTempDir` routine. `mkdir` fails when the name already exists, so processes that start in the same second, and therefore draw the same `%RANDOM%` values, retry with the next values instead of sharing a file. The directory is removed where the file used to be deleted. `JVM_CONFIG_DIR` and `JVM_CONFIG_TEMP` are cleared at the start, so a value inherited from the environment is never used or deleted. I have no Windows machine, so this has not been run outside CI. The Windows integration-test jobs on this PR run `MavenITmng4559MultipleJvmArgsTest`, which failed in three of four failed `master` builds on 2026-10-22 and 2026-10-23; one green run does not prove a race fixed. -- This is an automated message from the Apache Git Service.
