Install RVM:

$ curl -L get.rvm.io | bash -s stable

Install Jruby:

$ rvm install jruby

Use Jruby:

$ rvm use jruby

Install the bootstrapping gem:

$ gem install bundler

Install the rest:

$ bundle install

Install the Java libraries

$ mvn package

Run:

$ rails server

To use a development version of a library, you need to do the following before running rails server:

$ rm lib/name-of-library.jar

$ export CLASSPATH='lib/*'

$ ln -s /path/to/library/target/classes/* .

Yes, you really have to put the library into the root directory of cebu-rails. I’m not really sure why.

Remote debugging:

You’ll need to have openplans-tracking-tools set up in Eclipse as a maven project.

$ jruby -J-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8000 -J-Xdebug script/rails server

The server will wait for a debugger to connect.

Then, in eclipse, Run > Debug Configurations > Remote Java Application Click “new”. Select openplans-tracking-tools as the project. Click “Debug”. Now you can place breakpoints and do all the usual things.
