Java Question

JRuby / Warbler results in no such file to load -- bundler/dep_proxy

I have a large rails app converted successfully to use JRuby and it runs locally without any issues

bundle exec rails s -b 0.0.0.0
.

I'm now trying to create a deployable WAR file using the following:

bundle exec warble executable war


This completes successfully without errors, but when running it with:

java -jar application.war


It boots up and then after a few seconds, it spits out this error:

It's getting stuck by not being able to load bundler/dep_proxy and Googling hasn't resulting in finding similar issues. I've tweaked the warbler config file, but result in the same issue.

Warble Config File:

Warbler::Config.new do |config|
config.webxml.rails.env = 'development'
config.features = %w(gemjar executable)
config.dirs = %w(app config db lib log vendor tmp modules public)

config.excludes = FileList["test/*"]
config.bundle_without = ["development", "test", "assets", "doc"]
config.jar_name = "application"
end


An extend Warbler Config I've been using:

Warbler::Config.new do |config|
config.features = %w(gemjar compiled executable)
config.dirs = %w(app config db lib log vendor tmp modules public)
config.includes = FileList['Rakefile', 'lib/tasks/generate_ident.rake']

config.gem_dependencies = true

config.jar_name = "application"
config.compiled_ruby_files = FileList['app/**/*.rb', 'config/*.rb', 'config/**/*.rb', 'lib/*.rb', 'lib/**/*.rb', 'modules/*.rb', 'modules/**/*.rb']

config.webxml.rails.env = ENV['RAILS_ENV'] || 'development'
config.webxml.jruby.min.runtimes = 2
config.webxml.jruby.max.runtimes = 8
end


Is there a config or something else that I'm overlooking?

Update 2:

I've tried each version of bundler from the latest all the way down to 1.10 with exactly the same result.

I've also downgraded JRuby to 1.7.25, same issue.

Answer

The problem is the features line:

config.features = %w(gemjar compiled executable)

If I change it to:

config.features = %w(compiled executable)

I assume this is a bug since the documentation for Warbler states the following:

gemjar: This bundles all gems into a single gem file to reduce the number of files in the .war. This is mostly useful for Google AppEngine where the number of files per application has a limit. (Note: not applicable for jar-based applications.)
