Improved use of `java.io.tmpdir` #838

Closed jglick closed 4 weeks ago

jglick commented 1 month ago

Ensure that temporary files are written to target/tmp/ (where mvn clean can delete them) rather than the system temporary directory, including in RealJenkinsRule forked JVMs; note that in the test JVM it seems to be necessary to look up this system property explicitly, I think since Surefire sets the system property after startup rather than using -D, and something reads and caches the value soon after startup. Ensure that all temporary directories are deleted when the test exits. Use temporary directories instead of $JENKINS_HOME for anything added by the test harness rather than Jenkins itself. (Extracted from #827.)
