Michael Semb Wever commented on CASSANDRA-16704:
------------------------------------------------
Testing both patches.
Between builds on cassandra-4.0.0 and these patches, the {{lib/}} and
{{build/lib/jars/}} result in identical contents.
But the {{build/test/lib/jars/}} directory contains differences:
{code:java}
❯ diff <(ls build/test/lib/jars/) <(ls ../cassandra/build/test/lib/jars/)
11d10
< assertj-core-3.15.0.jar
15,18d13
< byteman-4.0.6.jar
< byteman-bmunit-4.0.6.jar
< byteman-install-4.0.6.jar
< byteman-submit-4.0.6.jar
22d16
< compile-command-annotations-1.2.0.jar {code}
;that is those jar files no longer appear under {{build/test/lib/jars/}} which
is the intentional of the patch (as they are already "provided" and so under
{{build/lib/jars/}}).

> Fix imports; run tests with packaged dependencies
> -------------------------------------------------
>
> Key: CASSANDRA-16704
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16704
> Project: Cassandra
> Issue Type: Bug
> Components: Build, Test/burn, Test/unit
> Reporter: Angelo Polo
> Assignee: Angelo Polo
> Priority: Normal
> Fix For: 4.0.x, 4.x
>
> Attachments: cleanup-imports.patch, dedup-deps.patch
>
>
> Tests are currently run with a classpath containing _all_ downloaded jars.
> The tests would be more reflective of the behavior of a runtime environment
> if the test classpath only contained jars that are bundled with the binary
> release, together with explicit test dependencies. Ideally we'd use the
> build/lib/ jars for the classpath since that's what gets packaged, but since
> these aren't available at test compile time and should be identical to lib/
> anyway, I've used the later.
> Doing so exposed a couple of references in src/java to
> "org.apache.commons.lang", which is not available at runtime (should be
> "org.apache.commons.lang*3*").
> Attached patch modifies the test classpath, fixes various imports in both
> test/ and src/ classes, and makes some simple substitutions in the tests such
> as using AbstractMap.SimpleEntry in place of
> org.apache.commons.collections.keyvalue.AbstractMapEntry.
