Maven: updating you version tags

When you create another branch of your multimodule maven project, updating version tags all over the hierarchy can be a pain. You keep that snippet of code that does the job with 'find -iname pom.xml | xargs sed -e 's/4.0-SNAPSHOT/5.0-SNAPSHOT/g' .. and it works in most of the cases.

But there's another way: using the maven-versions-plugin. It allows you to change the pom version and parent version with a single target, e.g. mvn versions:set -DnewVersion=4.0b-SNAPSHOT.

Now, all of your maven modules in this project have been updated to the correct version, and their parent dependencies as well. Voilà :)

Speeding up the development cycle at JavaZone

JavaZone 2009 has come to an end. It was a top notch conference: Great speakers and free beer.

My contribution was a lightning speed with entitled Speeding up the development cycle: Stash your files on a Solid State Drive

The abstract reads: Solid state drives have recently become easily available. Their performence may provide a way of reducing the time spent on on the development cycle: compiling, packeting and deploying applications. This paper shows promising results by locating the code base and local maven repository on a solid state drive. Initial experiments shows that time spent on waiting for your code to compile may be reduced by 50%.
