/**
 * Assists in detecting wagon providers brought into the plugin class path via legacy Maven core artifacts (e.g.
 * maven-core:2.0.6) and excluding them. A plugin should be able to explicitly declare dependencies on specific wagons
 * for its use. However, the (old) wagons pulled in transitively via legacy Maven core artifacts are usually not
 * intended as dependencies and more importantly screw up artifact resolution because they would get preferred over the
 * core wagon versions. This is a hack to provide backward-compat with Maven 2 (MNG-4528, MNG-4561).
