I've added removeStaleArtifacts which is automatically run after publishing the release to /release/jmeter/...
The task can be called manually: $ gw removeStaleArtifacts -PasfDryRun -Pjmeter.version=5.2 # keep 5.2 artifacts, and print the files to be removed $ gw removeStaleArtifacts -Pasf -Pjmeter.version=5.2 # keep 5.2 artifacts, and remove the other files The set of files to keep is configured in /build.gradle.kts -> staleRemovalFilters { ... } The missing bit is to drop stale Nexus staging repositories. It could be implemented as https://github.com/gradle-nexus/publish-plugin effort stabilizes. Vladimir
