JRuby / Warbler / GlassFish - (NameError) uninitialized constant ApplicationController::SessionsHelper

Question

Really Short Story: I'm incredibly frustrated by this issue

---

Short Story: JRuby-1.7.2 building to a .war using Warbler (1.3.8) deploying to a glassfish v3 server. I can build on my machine and everything works fine, however when I try to build with Jenkins, the war gives the following error when trying to load the first page:

org.jruby.exceptions.RaiseException: (NameError) uninitialized constant ApplicationController::SessionsHelper

---

Long Story: Build script on our Jenkins server:

#path to rvm
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
# Use the correct ruby
rvm use "jruby-1.7.2@webadmin"
# Set "fail on error" in bash
set -e
# build
bundle update
warble compiled war

Error log from Glassfish....which I hope has enough info.

Answer 1

Turns out it was an issue with source code control. My helpers directory was not added and therefore Jenkins was not including in the build. Always check the obvious first, if it says it isn't there it probably isn't.
