We now publish snapshots:

Suggested change

	assertj = "4.0.0-M1"
	assertj = "4.0.0-SNAPSHOT"

Thanks! You don't publish snapshot Javadoc anywhere, do you?

[scordio]

If I'm not mistaken, the Javadoc JAR also gets generated and published to Maven Central, but I don't know how its content could be consumed/linked.

As part of version 4 work, I plan to publish the Javadoc also to our own domain to relax a bit the dependency to javadoc.io, and the new publishing will also include snapshot content.

Looks like xmlunit needs to be adjusted due to assertj/assertj@989faf8
