Subject Re: Maven 3 Plugin Development with Repository Queries
Date Mon, 28 Jul 2014 18:49:57 GMT

maven-dependency-tree and maven-compat to resolve artifacts. Take a look at
maven-dependency-plugin, maven-report-info-plugin, license-maven-plugin for
various sample code.  However, those are not directly deal with aether
