Hi @Haarolean,

Here is another PR to bump versions of several components, trying to go to Java 21 another step to #490.

I still haven't been able to run the smoke, regression or sanity tests on my Mac M1. I've managed to solve some issues around docker incompatibilities like kdsqldbor the create-connectors images in the documentation/compose/e2e-tests.yaml file.

[Haarolean]

Yeah I remember having issues with running e2e on m1 as well, mostly due to x86-based images in e2e compose. As an alternative, you can run them in your forked repo.

[sixdouglas]

The build is failing, it seems that it uses the version of the scripts on the main branch and not the updated ones in the PR.

As an alternative, you can run them in your forked repo.

I didn't know I could do that, do you have a link to explain it?

[sixdouglas]

I still can't make the e2e tests work locally.
But I was able to reproduce and fix the exception raised in the smoke tests you run.

sorry I don't have any articles on this, the point is that you can fork the repo and run whatever changes you need even on modified workflows in the fork repo :) There will be some failing tasks (due to lack of set secrets) like release and e2e reports uploading, but that's not that important.

oh, thanks much! 😄

[Haarolean]

All workflows seem to be passing successfully on a fork
