Indeed this fixes it and I start to see something going ... Thanks a lot! Last question:
the diff between project.getDependencies() and project.getDependencyArtifacts() is basically that getDependencies() returns also transitive dependencies? I'm assuming it follows the guidelines as documented at http://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html. Chris "Brian E.

I will take a look at the code of the plugin. However, just a fyi: project.getArtifacts() returns an empty list for me (even that I have dependencies defined, and I get them listed with my own plugin and with "mvn site"). The same with project.getDependencyArtifacts() (and I don't exactly understand what this should do anyways) except that it returns "null". Thanks, Chris "Brian E.

Basically you just need to call project.getArtifacts and that will be all transitive included. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Saturday, January 07, 2006 9:59 PM To: Maven Users List Subject: Re: [m2] How to get artifact and Maven project for dependencies and transitive dependencies Thanks for the point Allan. However, I need to clarify that I'm not trying to resolve the dependencies within my plugin. My plugin does create a dependency report similar to project-info-reports:dependencies, however with the output as XML file, so that it can be rendered into various formats (e.g. XHTML, Plain text, PDF, etc.). I basically looked up the code in the plugin maven-project-info-reports-plugin, but it contains a lot of "TODOs". That's why I'm not sure if there is a better way to do the dependency resolution.
