It looks like I was wrong about there not being an easy way to get the
plugin classpath. From the Cobertura plugin:
/**
* <i>Maven Internal</i>: List of artifacts for the plugin.
*
* @parameter expression="${plugin.artifacts}"
* @required
* @readonly
*/
protected List pluginClasspathList;
This contains a list of org.apache.maven.artifact.Artifact objects.
The Cobertura uses the pattern you are describing, so I would suggest
you take a look at it.

Justin , just one more small question.
The project.getCompileClasspathElements() , gets me the elements of the
classpath of the project that the plugin is actually running , but not
of the plugin itself , so i had to add plugin dependencies also to the
pom.xml where the plugin is configured. Is there a way to get the plugin
classpath too ?
Thanks in advnace
Roman
