Delete old builds from the server when deploying a new one

Summary

  • The copy-artifact job copied a new timestamped mtsa-build.<timestamp>.jar to /var/www/mtsa/download/builds/ on every master pipeline and never removed old ones, so the server was filling up.
  • After copying the new jar and updating the mtsa-latest-build.jar symlink, the job now deletes all but the KEEP_BUILDS most recent builds (set to 5 in the job's variables).
  • The just-copied jar is always the newest, so it is never deleted, and the mtsa-latest-build.jar symlink doesn't match the mtsa-build.*.jar pattern, so it isn't touched.
  • Tagged releases in /var/www/mtsa/download/releases/ are not affected.

Note: the first master pipeline after this merges will delete every build except the 5 newest. Links to older timestamped builds will stop working.

Test plan

  • YAML parses; the cleanup command was run against 14 dummy build files: it removed the oldest, kept the newest, and left the symlink working.
  • After merging, check the copy-artifact job log for "Removing ..." lines and confirm /var/www/mtsa/download/builds/ holds 5 builds plus mtsa-latest-build.jar.
