Thanks for this @JamieSlome !

I'm not sure this is the right solution (in fact, this PR should not have triggered the build/preview in theory); please keep in mind that we also need to rebuild against changes to the docs folder.

I'd suggest the following content on netlify.toml:

[build]
  ignore = "git diff --quiet $CACHED_COMMIT_REF $COMMIT_REF . ../{docs,website}/"

This is currently working for FDC3, see https://github.com/finos/FDC3/blob/master/netlify.toml

How can we re-test this @mao?

@JamieSlome , just realised that docs is a subfolder of website, so we can probably update this to :

[build]
  ignore = "git diff --quiet $CACHED_COMMIT_REF $COMMIT_REF . ../website/"

Re. testing, it's probably ok to merge and run some PRs to see what's going on. I know it's not ideal.

Updated, but still seems to be running even on this PR (@maoo)

Could be that netlify.toml changes always triggers a build? Found this discussion to be relevant - https://answers.netlify.com/t/builds-cancelled-for-a-new-branch-due-to-no-content-change/17169

I'd try to merge some of these changes to main and see if there's any change in behaviour.
