"Unable to detect bundler spec under <gem path>"

[seanstory]

Environment:

• rbenv 1.2.0
• jruby 9.3.3.0
• bundler 2.4.6
• warbler 2.0.5
• OSX 13.2

Issue

When running bundle exec warble I get this error:

Unable to detect bundler spec under '/opt/homebrew/Cellar/rbenv/1.2.0/versions/jruby-9.3.3.0/lib/ruby/gems/shared/gems/bundler-2.4.6'' and its sub-dirs

This makes sense, as there's no gemspec file there, just a exe/ dir with bundle and bundler executables. The gemspec for bundler lives in

/opt/homebrew/Cellar/rbenv/1.2.0/versions/jruby-9.3.3.0/lib/ruby/gems/shared/specifications/default/bundler-2.4.6.gemspec 

Workaround

I copied the gemspec to where warbler seems to be looking for it, and now it's working. However, I expect this will fall apart if/when I update my bundler gem.

cp /opt/homebrew/Cellar/rbenv/1.2.0/versions/jruby-9.3.3.0/lib/ruby/gems/shared/specifications/default/bundler-2.4.6.gemspec opt/homebrew/Cellar/rbenv/1.2.0/versions/jruby-9.3.3.0/lib/ruby/gems/shared/gems/bundler-2.4.6/bundler.gemspec

@seanstory Yes, we have had valiant efforts to try to support Bundler 2.x.

Thanks for your report!

So there is no fix for this at the moment?
