Maven Plugins

The other day I wrote a post about examining dependencies in maven plugins. Today I was working on a similar project, and I discovered some non-intuitive behavior with the Maven ArtifactResolver. Several of the resolveTransitively methods accept an ArtifactFilter, but the filter gets applied in an odd way.

After you’ve worked with Maven for a while, you’ll eventually find a need to extend it. While there are some means of executing arbitrary code as part of your build, the best way to handle such needs is to create a maven plugin. The task may seem a bit daunting at first, but you’ll learn a lot about how maven works by doing it. Listed below are the properties that you need to define to examine the dependencies of a maven project from within a plugin. The following code would be placed inside a Maven Mojo.
