Bundler incorrect path resolution handling classloader URI #6045
Description
I have built a JAR using warbler where my Gemfile contains a gem using the :path argument.
The :path points to a sub-directory.
gem 'some-gem', :path => "ruby-gems/some-gem"The gem is present (actually twice on account of jruby/warbler#465) in the built JAR:
jar -tf my-application.jar
gems/some-gem-1.0/
gems/some-gem-1.0/Gemfile
gems/some-gem-1.0/Gemfile.lock
gems/some-gem-1.0/some-gem.gemspec
gems/some-gem-1.0/lib/
gems/some-gem-1.0/lib/code.rb
gems/some-gem-1.0/test/
...
my-application/ruby-gems/some-gem/
my-application/ruby-gems/some-gem/Gemfile
my-application/ruby-gems/some-gem/Gemfile.lock
my-application/ruby-gems/some-gem/README.md
my-application/ruby-gems/some-gem/Rakefile
...
The JAR however fails to startup with the error: [!] There was an error parsing `Gemfile`: different prefix: "uri:classloader://" and "uri:classloader:/my-application". Bundler cannot continue.
You can find a small reproduction project: https://github.com/fzakaria/warbler-bundler-jruby-failure
bundle exec warble
java -jar warbler-example.jar
[!] There was an error parsing `Gemfile`: different prefix: "uri:classloader://" and "uri:classloader:/warbler-example". Bundler cannot continue.
# from uri:classloader:/warbler-example/Gemfile:4
# -------------------------------------------
# gem 'warbler', '2.0.5'
> gem 'jruby-jars', '9.1.17.0' # ruby '2.3.3', engine: 'jruby', engine_version: '9.1.17.0'
# -------------------------------------------The failure is present only once the following line is included:
require "bundler/setup"
Bundler 2.1.4 is needed to trigger the issue & I believe might be related to the commit rubygems/bundler@c7532ce
which introduced use of relative_path_from
