open-sourceNote: Before we get started, anyone interested in signing up for Maven training should do so soon. We’ve got a class in Mountain View, CA on May 12-13, and a class in Chicago on May 19-20. Sign up today. It’ll be great, and we’ve got some new material from John Smart, author of “Java Power Tools”.

Alright, we’ve put the infrastructure in place for more participation in the development of Maven: The Definitive Guide. We’ve already had two forks of the Definitive Guide on GitHub.

Tycho: Implicit build target platform support from Maven!


April 16, 2009 By Jason van Zyl

At Sonatype we are trying very much to bring the Maven, OSGi and Eclipse worlds together and Tycho is a big part of this strategy for us. Tycho is a set of sophisticated plugins for Maven that makes OSGi bundles first class citizens in the Maven world. We use OSGi metadata, we use MANIFEST.MF files for dependency information, and we use OSGi resolving strategies.

Today we have our first publicly available version of Tycho with implicit build target platform support. In a nutshell we deal with target platforms in much the same way we deal with dependencies in Maven. We figure out what you need, and we’ll go get it from a set of remote repositories for you.

This was back in the 2.0-beta-1 days (2005) so many of the tools have changed to make life easier, but I think the general process I used is still applicable to users migrating today. I’ll try to focus on the generic approach and leave specific details to the best practices documented elsewhere on this blog or in the Maven book.

Migrating from Ant to Maven requires a few basic steps: Continue reading →
