@jonasrutishauser thanks for this interesting feature. Could you share an example repo you've tested against?

I created a simple example repo https://github.com/jonasrutishauser/renovate-32550 and I have run pnpm start jonasrutishauser/renovate-32550.

please split this PR into three parts

• worker
• datasource
• manager

you can use this PR for one of them and the order probably doesn't matter.

[jonasrutishauser]

As requested this now only contains the worker part.
The datasource part is in #32636 and the manager part is in #32635.

@jonasrutishauser, do we understand why on your test repo, there's no PR for Ant 1.7.0? Is that just a matter of throttling, or is there a reason why the replacement does not get noticed?

I think the reason is, that the version 1.7.0 has no timestamp in the html and is therefore ignored/not seen. In the maven-metadata.xml this version is missing too.
