quarkus-resteasy-common depends on groupId com.sun.activation but rest-assured depends on groupId jakarta.activation

[ge0ffrey]

I am seeing this in my mvn dependency:tree:

58-[INFO] |     +- io.quarkus:quarkus-resteasy-common:jar:1.5.0.Final:compile
59-[INFO] |     |  +- ...
63:[INFO] |     |  \- com.sun.activation:jakarta.activation:jar:1.2.1:compile

181-[INFO] |  \- io.rest-assured:xml-path:jar:4.3.0:test
182-[INFO] |     +- jakarta.xml.bind:jakarta.xml.bind-api:jar:2.3.2:test
183:[INFO] |     |  \- jakarta.activation:jakarta.activation-api:jar:1.2.1:test

This leads to:

16:01:54 [WARNING] Rule 0: org.apache.maven.plugins.enforcer.BanDuplicateClasses failed with message:
16:01:54 Duplicate classes found:

Suggestion on how to fix: Add enforcer rule <banDuplicateClasses> and see what breaks.

Relates to #9839
Relates to rest-assured/rest-assured#1332 (= separate issue) and rest-assured/rest-assured#1333

Just hit this issue too, it is still present in the latest Quarkus release.

We have the banDuplicateClasses enforcer rule globally activated.

Yeah, it's not so easy to use banDuplicateClasses in our case as there are a ton of issues that are not fixable by us directly. Typically like the REST Assured issue.

That being said, I'll have a look at what @sebthom is showing as I wouldn't expect it to break on our own dependencies.

I pushed a PR that should this one issue: #19422 .
