The log gave no indication of what actually failed, and it looks like it is expanding the jruby package in the temp directory. I'm flummoxed. :(

Hi, sorry for the trouble! I suspect that this line failed:

ruby-build/bin/ruby-build

Line 873 in 076d1a2

jruby_version="$(./ruby -e 'puts JRUBY_VERSION' 2>/dev/null)"

When it fails, ruby-build would abort but the error stream is unfortunately silenced, so nothing would get printed in ruby-build output. I've opened a PR to avoid/fix this.

To get to the bottom of why this fails for you, you could try cd'ing into your ruby-build temporary directory and running jruby-9.4.7.0/bin/jruby -e "puts JRUBY_VERSION" there.

Weirdly, I just tried again and it worked? 🤔 I'll leave this open in case someone else hits a similar issue.

[mislav]

Did you upgrade ruby-build between attempts? I had merged #2406 based on your report.

[aarestad]

I don't think so, but it's possible I did in passing. :) Anyway, It Just Works. Now I have to track down a zillion other JRuby issues with my huge monolith app. 🫠 Thank you for your help!

Happy it works now. I'm going to mark my best guess as an answer, and since the aforementioned PR shipped, there is a good chance that whatever caused the failure will be logged in the future. So here's to hoping no one will need to scratch their head over this.
