I'm (not yet) comfortable going with the scripted pipeline approach (ie using 
{{node}}).

While the declarative approach (using {{pipeline}}) is more opinionated, it 
provides a better UI and is recommended by the Jenkins developers.

I've taken your suggestion, and created just a function for the CopyArtifact 
duplication. That [removes 
120|https://github.com/thelastpickle/cassandra/commit/fff7b798c5409b10094fee57c18674f3f918f262]
 lines of boilerplate, a big win, thanks! Beyond that improvements like 
https://issues.jenkins-ci.org/browse/JENKINS-42224 and/or 
https://issues.jenkins-ci.org/browse/JENKINS-49135 would look to be a direction 
to take.

I've updated the patches above.
I've also undone the {{'s/long-test/test-long/`}} rename altogether. While only 
in test code, making that change against all the branches seems a little 
excessive.

> *Declarative Jenkins pipeline*
> Currently all the jenkins build jobs are generated by the DSL job from the 
> cassandra-builds repository.
> For a given branch, there are numerous builds: artifacts, unit tests, and 
> dtests.
> Using a (declarative) {{Jenkinsfile}} in-tree these builds can be put 
> together into per-branch pipelines.
> Per-branch pipelines will give a nicer UI (via blue ocean) and one place to 
> look at test results for any branch and commit. From there we can post one 
> complete test summary on commits back to the related jira ticket.

> *Removing {{`ant test-all`}}*
> Currently the test-all target does nothing but execute the test target.
> This is because the test targets finishes with unit test failures.
> As these jenkins jobs are automated here: 
> https://github.com/apache/cassandra-builds/blob/master/jenkins-dsl/cassandra_job_dsl_seed.groovy#L44
>  ; it is easy enough to remove the "test-all" target, replacing it with 
> separate jobs for 'stress-test', 'fqltool-test', and 'long-test'.
