Package org.apache.maven.plugin.internal

Class PluginDependencyResolutionListener

java.lang.Object

org.apache.maven.plugin.internal.PluginDependencyResolutionListener

All Implemented Interfaces:

ResolutionListener

class PluginDependencyResolutionListener
extends java.lang.Object
implements ResolutionListener

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).

Since:

3.0
