Hi @sanyakapoor27, thanks for your commit!

However, I suggest not adding version constants in all child POMs, as this could make maintenance more difficult. It’s better to remove the version tags from child POMs.

[yecol]

See comments.

Hi @yecol, thanks for the review!
I had added the constants to remove the "'version' contains an expression but should be a constant." warning. It looks like that warning might still pop up when expressions are used in child poms, but I definitely understand your concerns about maintenance. I'll make the suggested changes! :)

[yecol]

Thanks for the prompt update!
However, according to the build log in CI, it seems there’s still a version variable in the root POM of the maven-projects.
I believe you’ll also need to change the version in line 32 to the hardcoded value 0.12.0-SNAPSHOT.

Hi @sanyakapoor27 , Ubuntu 20.04 LTS runner has been removed on 2025-04-15(link). I will contribute a PR to fix the error. You can rebase the main branch after the updating of GitHub Action Runner : )

[sanyakapoor27]

@yecol thanks for the review once again! I had previously updated line 32 of the root POM to 0.12.0-SNAPSHOT, but that led to "[FATAL] Non-resolvable parent POM" errors when building the child modules.

This error and the warning mentioned in the issue #688 were gone when the < version> in the child poms also referred to 0.12.0-SNAPSHOT. This can be viewed here: Stack Overflow. In such a case, please let me know what would be the best course of action?
