+name: Publish Maven packages
+
+# Flash's own POM keeps `2.1.0-SNAPSHOT` as its committed version — that's what local
+# `mvn install` (Pathway's normal dev loop, see its pom.xml `flash.version` comment) always
+# produces, and changing it here would break that. Gitea's Maven registry, unlike a real
+# snapshot repository, refuses to re-publish an existing name+version (must delete first —
+# see https://docs.gitea.com/usage/packages/maven#publish-a-package), so every push instead
+# publishes under a throwaway version stamped with the commit it built from
+# (`2.1.0-<short-sha>`), via `versions:set` on a checkout copy — never touching the committed
+# POMs. Consumers (Pathway's `docker` Maven profile) pin `flash.version` to one specific
+# published build and bump it by hand to pick up newer Flash changes; see
+# pathway/pom.xml's `docker` profile for the other half of this.
