How should I represent a library with two configurations in Maven
Central?
I’ve posted a question on StackOverflow that has not yet been answered.
Perhaps someone here has an answer?

On behalf of all ignorant people, thank you for explaining yourself.

You don't have to exclude a dependency based on its version, this does not
make sense.
Maybe you should make yourself familiar with what a dependencyManagement
section is used for.
If you use classifiers, you have different artifacts for the same G:A:V and you
have no proper way to chose one if different ones are in your transitive deps.
With different versions you have different G:A:V and you can manage the correct
one yourself.

I know that. But you also can’t exclude a dependency based on its version.
So, what comparison are you making?

Good point, never thought about that.
One downside of "flavors" / "configurations" in the version is that you
cannot filter them out properly with dependabot, e.g.:
https://github.com/quarkusio/quarkus/pull/11961

You cannot exclude a dependency based on its classifier.

I would still like to understand what you meant when you said that classifiers are worse then versions.

You won't have to exclude something. A user of your library will just add a
dependencyManagement section to his/her build and select there the version (with A or B)
he/she wants. That will select the wanted version even if your lib is a transitive
dependency.

+1
Use version suffixes, and think about deploying Gradle Module Metadata so
Gradle users can see them as variants of one another and more accurately
pick a version:
https://docs.gradle.org/current/userguide/publishing_gradle_module_metadata.html
and e.g. https://github.com/google/guava/pull/3683

Hi Alan,

If it is A or B exclusively, use the alternatives as part of the version string. See
- postgres (https://search.maven.org/artifact/org.postgresql/postgresql[1] )
- xstream (https://search.maven.org/artifact/com.thoughtworks.xstream/xstream[2] )
Bouncycaste uses the alternative as part of the artifactId:
- https://search.maven.org/search?q=g:org.bouncycastle[3]
However, I have often to "manage" 3rd party libraries manually that reference one of the
BC artifacts that should not be used together by using exclusions.
Using a classifier is worse, because exclusions do not work on classifiers.

Jörg
