From the CI logs (Python CI):

[info] Built: /home/runner/work/graphframes/graphframes/graphframes-connect/target/scala-2.13/graphframes-connect-spark4_2.13-0.0.0+1-9996b40f-SNAPSHOT-spark4.0.jar

As you can see, the version is automatically generated by the plugin based on the github tags. The only reason version is 0.0.0 here is because sbt-ci-release requires:

    steps:
      - name: Check out code
        uses: actions/checkout@v4
        with:
          fetch-depth: 0

to get the full git history and tags information. It is specified in publishing CI, but it is not needed for testing.

I also tested it locally and it works fine:

sbt:graphframes> publishLocal
[info] Wrote /var/home/sem/github/graphframes/target/scala-2.12/graphframes-spark3_2.12-0.9.0+1-f554aaf9-SNAPSHOT-spark3.5.pom

where f554aaf9 is exactly the hash of the commit of this PR.

So, long story short, it works.

How do snapshots work now?

In the same way except the commit hash is added to the version string
