Jacek Lewandowski commented on CASSANDRA-18017:
-----------------------------------------------
That is great! I didn't know that and thought it took around an extra minute.
But I stick with my opinion - when I run a "test" target, I want to run a test
- not a static code analysis. In particular, I want to avoid being forced to
fix all the issues to run a test. When we add a checker framework, which
enforces additional rules, it will become even more annoying.
Would running the incremental validation with the "jar" target but not with the
"test" target be a compromise?

> CASSANDRA-16625 and CASSANDRA-18000 added a {{-Dno-build-test=true}} flag to
> skip the dependencies of the Ant test targets. This is useful to speed up the
> test targets if the {{build-test}} target has already been previously run,
> for example as part of {{{}ant jar{}}}.
> That was created thinking mainly on CircleCI's multiplexer, where we run the
> same test target repeatedly. Skipping the already run depended on targets can
> significantly speed up the tests. The flag however is also useful for all
> other test jobs because every parallel runner can skip the test building
> step, and we have hundreds of parallel runners. Saving around 30s on every
> runner adds up considerable savings.
> Maybe this flag can also be used for skipping test builds on Jenkins too, so
> each parallel test split can benefit from a slight boost. That could be done
> if either {{build-test}} or {{jar}} have already been run before calling the
> test target. I'm not familiarized with Jenkins config so I'm not sure whether
> it makes sense.
