hi @amvanbaren, do you know why this is failed https://github.com/EclipseFdn/publish-extensions/actions/runs/15301776884/job/43043958569?pr=881

The reporting functionality is broken:

publish-extensions/.github/workflows/publish-extensions.yml

Lines 50 to 77 in 7420c17

There's a check for important extensions: https://github.com/EclipseFdn/publish-extensions/blob/f7cfb5c517bbf53d772704383db8b22b4cb895aa/report-extensions.ts#L226C1-L232C2

Because the reporting functionality is broken every extension is seen as outdated and the Validate PR job fails.

In general, I'm aligned and happy with this approach --> we never really did publishing outside of GitHub Actions anyway.

I'm curious about:

• How does our local testing story look like? I used to run node publish-extension.js with a list of extensions when debugging build issues with certain extensions
• How can we test the PR before landing it? If it's not worth the effort to do here, I'm also fine with merging it and testing then
• Do we have an idea on how this will affect timing? I know there's some concurrency limits for GHA workflows, so given there's > 400 extensions, I worry the publishing times might get lengthy.

Does resolveExtension have a side effect we need here or can we safely remove it?

Nice, I like finally not having everything in the root 😄

Can you please run npm run format here?
