Description

Many maven plugins are wrapper around other tools. The plugin is designed for a version of the tool, and in many case user will want to use a specific version without having to patch the plugin. The <dependency> element on plugin configuration is a common way to do this, by overriding the plugin POM dependency with another version.

<plugin>
<artifactId>castor-maven-plugin</artifactId>
<dependencies>
<dependency>
<groupId>org.codehaus.castor</groupId>
<artifactId>castor</artifactId>
<version>VERSION OF CASTOR I WANT TO USE FOR CODE GENERATION</version>
</dependency>
</dependencies>
</plugin>

This used to work with maven < 2.0.8

In maven 2.0.8, this doesn't work anymore as the <dependency> set in plugin configuration is added to plugin classpath, as a duplicate for the one declared by the plugin but LATER in the classpath (but I may be wrong on this analysis).
