https://github.com/cloudfoundry/php-buildpack/pull/855 should fix this.

The issue is that during the detect phase, multiple buildpacks provide their own ruby (as we have removed it from the stack). All buildpacks look in /tmp/ruby/ for this provided ruby. But, the php buildpack requires a different version of ruby than the others (3.0 vs 3.1). This issue is resolved by installing (and looking for) ruby under a unique namespace e.g. /tmp/php-buildpack/ruby/.

This issue doesn’t show up when running cf push -b - i.e. when skipping detect - because only during detect do multiple buildpacks run on the same filesystem in sequence. It’s possible this would be an issue when using the php buildpack in a multi-buildpack scenario with another buildpack first, but we didn’t validate that. Regardless, the fix above should resolve the issue.

I’ve sent access credentials via Slack to rdz. Once the deploy job finishes successfully, you can try to reproduce the problem. Thanks for the quick support!

Ok, then I’ll start the experimental jobs, but they won’t finish before our EOB. I can provide you the access information tomorrow on Slack.

I am looking into this!
