however i can run a test ruby file same from shell and it works OK

[root@jenkins01 etc]# su -c " source /usr/local/rvm/scripts/rvm && rvm use --install --create ruby-1.9.3-p484 && export > rvm.env ; ruby -v /tmp/test.rb" -s /bin/bash jenkins
Using /usr/local/rvm/gems/ruby-1.9.3-p484
ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux]
hello

I think its missing this file..." /tmp/hudson4593249725887441871.rb" but as user "jenkins" I can create files in /tmp directory fine....

Any ideas where the issue will be?

Most likely, Jenkins cannot find the Ruby path, which is why it is giving a file not found exception. Try the below steps:

  1. Execute 'which ruby' - this will give you the full ruby path
  2. Replace this path in your program so instead of just writing ruby, give the full path.

The stack trace basically means the build process Jenkins started can not find ruby executable.

Use RVM Jenkins plugin if you can. And it:

Runs your entire build (from SCM check out to post-build actions) within the context of an RVM managed environment of your choice (as opposed to your doing "source ~/.rvm/scripts/rvm && rvm foo@bar", which only affects your current shell)

If the Ruby/gemset you specified doesn't exist on a slave that the build is running, it'll be automatically installed and created (via rvm_install_on_use_flag)
