Help -- trying to build Apache ODE source code with Buildr

Question

Hi, i am trying to build APACHE ODE source code with Buildr using Ruby. I installed ruby and installed Buildr with it, but when i run the command rake package on the root of APACHE ODE source code it gives me this error

C:\workspace2\APACHE_ODE_1.X>rake package --trace (in C:/workspace2/APACHE_ODE_1.X) rake aborted! uninitialized constant Gem::Requirement::OP_RE

The gems i have installed

C:\workspace2\APACHE_ODE_1.X>gem list

* LOCAL GEMS *

Antwrap (0.7.0) archive-tar-minitar (0.5.2) builder (2.1.2) buildr (1.3.5) highline (1.5.1) hoe (2.3.3) net-sftp (2.0.2) net-ssh (2.0.15) rake (0.8.7) rjb (1.1.6) rspec (1.2.8) rubyforge (1.0.5) rubygems-update (1.3.6) rubyzip (0.9.1) xml-simple (1.0.12)

I am suffering from the same problem and so are others (see this this bug ticket).

Upgrading to Buildr 1.4 should fix the problem.

Edit: I just tried upgrading to Buildr 1.4.

There wasn't a package anywhere so I got it straight from GitHub, here are my steps.

git clone http://github.com/apache/buildr.git
cd buildr
sudo gem build buildr.gemspec
sudo env JAVA_HOME=$JAVA_HOME gem install buildr-1.4.0.gem

This fixed the problem described in the question. I was though unable to install Apache Ode because of a new problem, but if you don't run into that one then no reason for me to try to find out the cause for it yet :)
