Tomás Lin’s Programming Brain Dump

In this post, I will show how to build a simple yet robust resource modification engine for Maven using GMaven and Groovy Templates.

We sometimes need to generate files in our build cycle that are specific to each server and change per deployment cycle. For some projects, this might be Flash / Flex actionscript files that need to reference the build server. For others, it might be datasource locations that change per build project. While maven provides a built-in resource filtering mechanism, it is tied to parts of the maven lifecycle that might not work well for all projects, and mostly changes resources for War files.

Groovy provides a very robust Templating engine. With the introduction of the GMaven plugin, it becomes possible to filter and re-write resource files using this robust mechanism. Combined with the power of Maven’s built-in profiles mechanism, this solution provides a robust and powerful way to edit Flex / Grails and other resources. Read the rest of this entry »

At work, we’ve used the Hudson continous integration engine to manage all our Maven project builds. I had to set up our Grails deployments so they rely on Hudson recently, and spent a few days playing with VMWare, Grails and Ubuntu. This guide will walk through all the steps needed to get a complete build server running Apache, Grails, Tomcat, Hudson on the VMWare server.
