Exception creating roxy jar

[joecrean]

This was a bug I previously discussed with @grtjn and @paxtonhare - here finally is the bug report...sorry it took so long

Testing on my local Mac environment. When I run ml jar i see the following exception:

~/Workspace/Thieme/ps-src-main/core-services/trunk -> ml jar

ERROR: You must be using JRuby to create a jar
Usage: ml jar

General options:
  -v, [--verbose]                   # Verbose output

Prerequisites:
  - You must be running JRuby http://jruby.org/
  - You must have the warbler gem installed
    > gem install warbler

This makes no sense to me - why should i be running JRuby to create the roxy jar file. The only pre-requisite should be that I have the jruby and warbler gems installed - which i do...

~/Workspace/Thieme/ps-src-main/core-services/trunk -> gem list

In order to workaround this problem i just commented out the first line in the self.jar method in server_config.rb - see below...

  def self.jar
    # raise HelpException.new("jar", "You must be using JRuby to create a jar") unless RUBY_PLATFORM == "java"
    begin
      # ensure warbler gem is installed
      gem 'warbler'
      require 'warbler'

      jar_file = ServerConfig.expand_path("#{@@path}/../roxy.jar")
      logger.debug(jar_file)
      Dir.mktmpdir do |tmp_dir|
        logger.debug(tmp_dir)

        temp_roxy_dir = tmp_dir + "/roxy"
        Dir.mkdir temp_roxy_dir

        FileUtils.mkdir_p temp_roxy_dir + "/bin"
        FileUtils.cp(ServerConfig.expand_path("#{@@path}/lib/ml.rb"), temp_roxy_dir + "/bin/roxy.rb")

        FileUtils.cp_r(ServerConfig.expand_path("#{@@path}/lib"), temp_roy_dir)

        FileUtils.cp_r(ServerConfig.expand_path("#{@@path}/sample"), temp_roy_dir)

        Dir.chdir(temp_roxy_dir) do
          Warbler::Application.new.run
          FileUtils.cp(Dir.glob("*.jar")[0], jar_file)
        end
      end
      return true
    rescue Gem::LoadError
      raise HelpException.new("jar", "Please install the warbler gem")
    end
  end

I see this error on my Mac with Roxy 1.7.2

Looks like you are right. The raiseexception, and mention of running with jruby are unnecessary. Perhaps jruby did not get bundled with warbler before?

I ran into this last night when working on a discrepancy in our JRuby integration and I will address it in the near future.
