Using Antwrap in Ruby

Hi ,

I am trying to install Antwrap-0.7.0.gem and rjb-1.1.x gems in cygwin
and windows also , I’m stuck so I thought I ping out to see if anyone
else has done
this. Last one week i have been working on issue .Any help would be
appreciated.

Error states that in this below manner.

$ gem install Antwrap-0.7.0.gem
ERROR: http://gems.rubyforge.org/ does not appear to be a repository
Building native extensions. This could take a while…

Hi Srinivasa,

there are two distribution of Antwrap:

  • This first one is for C based Ruby interpreter (MRI). It has a
    dependency on RJB (RubyJavaBridge), a gem that enables
    you to load and instantiate Java Classes from within a ruby process.
    Antwrap needs this to load and execute Ant tasks.

  • The second distro is meant to run on JRuby, and thus has no no
    dependency on RJB because it can load Java classes via the
    interpreter.

When you install Antwrap, it will ask you to choose the distribution
with the choice of Ruby or Java. You have chosen the first option, and
the failure is occurring during the installation
of RJB. It is trying to compile it’s classes using the gcc, but it is
having problems resolving the location of your JAVA_HOME (RJB needs to
link to some C libraries in the JVM).
This problem is probably due to the Cygwin paths. Try putting this
into your .bashrc or .bash_profile file:

export JAVA_HOME=$(cygpath -ua $JAVA_HOME)
export PATH=$JAVA_HOME/bin:$PATH

There are some other suggestions on how to solve this here:

Let me know how this goes for you.

Hi Caleb,

Thank for your helpful suggestions.

Installed rjb and antwrap successfully.Started working on antwrap.

My code is below.

options = {:ant_home=>“D://apache-ant-1.7.1”, :name=>‘BotServer’,
:basedir=>“C://InstantRails-1.3a-with-PHP-5.1.4//InstantRails//rails_apps”,
:declarative=> true, :logger=> Logger.new(STDOUT),
:loglevel=> Logger::DEBUG}
puts “options------------------------------1”
antProject = AntProject.new(options)
antTask = AntTask.new(‘ws-run -DD=PRnnn’, antProject, {:debug
=> ‘on’, :verbose => ‘no’, :fork => ‘no’})
puts “before task------------------------------”
antTask.execute()

While running i am facing problems.

-> up to options i was able to execute.
-> then i am getting error in this below manner (debugger not at all
excecute ant project code.)

My varaiables shows this value for creating instance for AntProject

exception uninitialized constant TestRunsController::AntProject
@blamed_files Empty Array
md nil
msg nil
origin_file nil
origin_line nil

Here TestRunsController is my controller.

Could you please help me in this regard.
