The failure is a LoadError for warbler_jar raised from lib/warbler/jar.rb (around lines 12, 19 and 336) when running under JRuby 10.0.4.0, and from the Rakefile line 8 in the linked test app. Start by checking how warbler_jar is resolved and whether the bundled-gems require replacement in that path is responsible, then try rails war or bundle exec warble on the test repo. Done means the build produces a .war file on JRuby 10 without the LoadError. This needs JRuby and Warbler packaging knowledge, and the thread has had no reply for six months.

Descrição

I’m testing a Rails 8.0.4 app on JRuby 10.0.4.0 using warbler from the master branch (as of April 7, 2026), and running into a build failure.

I've forked a previous reports minimal test app (from #560) for this test. The app is completely minimal and exists specifically to demonstrate this problem. You can find it here:

https://github.com/sis-berkeley-edu/warbler_test

Environment:

  • JRuby: 10.0.4.0
  • Rails: 8.0.4
  • Java: OpenJDK 21.0.8
  • Tomcat: 9.0.117
  • OS: macOS Sequoia 15.7.3 (Apple Silicon)
  • jruby-rack: master branch from jruby/jruby-rack
  • warbler: master branch from jruby/warbler

When I try to run a build with this test app, I get:

$ rails war
bin/rails aborted!
LoadError: cannot load such file -- warbler_jar (LoadError)
/Users/jason.c.miller/Developer/warbler_test/Rakefile:8:in '<main>'
bin/rails:4:in '<main>'
(See full trace by running task with --trace)

When I try to run a build from another project I receive:

$ bundle exec warble
bundler: failed to load command: warble (/Users/jason.c.miller/.rbenv/versions/jruby-10.0.4.0/lib/ruby/gems/shared/bin/warble)
