That's not correct. It should be SNAPSHOT version as the release is done by the maven-release-plugin.

Please use 18.3.0-SNAPSHOT

This is correct.

We don't create a release branch. We release a RC from main. So we should use no -SNAPSHOT version here.

FYI: We don't use maven-release-plugin for our release.

Ah, sorry. We use maven-release-plugin. https://github.com/apache/arrow-java/blob/main/dev/release/bump_version.sh that creates this PR uses maven-release-plugin.

[jbonofre]

Yea AFAIR we use the maven plugin in the release script.

Do you still think we need -SNAPSHOT version in this PR?
(I think that we don't need -SNAPSHOT version. Our next release script https://github.com/apache/arrow-java/blob/main/dev/release/release_rc.sh just tags the commit that merges this PR.)

I think it is fine. The caveat is that the main branch must be kept unchanged until the release is done.

Right. It's a restriction of the current release process.

Are you good with this PR? @jbonofre

[jbonofre]

Ok as soon as the version is bumped to SNAPSHOT after the release

[wgtmac]

Thanks! Let me merge it and proceed.
