I have recently been struggling with what I think is the same as you
want. I am developing a plugin which in the plugin code I want to
retrieve the plugin's, not the current project's, dependencies.
I found the parameter expression I was after in this FAQ:
http://docs.codehaus.org/display/MAVENUSER/FAQs-1#FAQs-1-HowdoIgetaplugin%27sdependenciesfromaMojo%3F
This gives me the plugin's dependencies:
/**
* @parameter expression="${plugin.artifacts}"
* @required
*/
protected List<Artifact> pluginDependencyArtifacts;
This gives me the local repository paths to each dependency:
for( Artifact artifact : pluginDependencyArtifacts )
getLog( artifact.getFile().getAbsolutePath() );
Hope this is what you're after :)

The ${project.dependencies} is not the correct one, since it gives me the
dependencies of the project, not the plugin! Also, it resolves the
dependencies transitively!

When using those interfaces, add something similar to these lines in your
MOJO:
/**
* @component
role="org.apache.maven.artifact.resolver.ArtifactResolver"
* @required
* @readonly
*/
private ArtifactResolver artifactResolver;
Now, you can use
artifactResolver.resolve(artifact)
for you artifact (if it has not been resolved already), after which you can
ask the artifact
artifact.getFile()
which will give you the full path to the JAR/POM/whatever file of this
artifact.
For my situation though (dependencies of the plugin), I use the following
code:
for (Object object : this.project.getPluginArtifacts()) {
Artifact artifact = (Artifact) object;
if ("my.group.id".equals(artifact.getGroupId())
&& "myArtifactId".equals(artifact.getArtifactId())) {
for (Object object2 :
this.artifactMetadataSource.retrieve(artifact,
this.localRepository,
this.project.getRemoteArtifactRepositories()).getArtifacts()) {
Artifact artifact2 = (Artifact) object2;
this.artifactResolver.resolve(artifact2,
this.project.getRemoteArtifactRepositories(), this.localRepository);
JarFile jarFile = new JarFile(artifact2.getFile());
JarEntry workflow = null;
for (Enumeration<JarEntry> jarEntries = jarFile.entries();
workflow == null && jarEntries.hasMoreElements();) {
JarEntry jarEntry = jarEntries.nextElement();
if (jarEntry.getName() != null &&
jarEntry.getName().endsWith("filename.extension")) {
workflow = jarEntry;
}
}
if (workflow != null) {
workflowFiles.add(workflow.getName());
}
}
}
}
In short, this code runs through the plugins until it finds the one I'm
looking for ("my.group.id" & "myArtifactId"). It then retrieves this
artifact
from the repository and gets its dependencies.
Those are resolved (to make sure all properties have been initialized -- eg
fileName doesn't work without it) and opened as JAR-files (atm I'm sure they
are JARs, but need to change this code to make sure it doesn't fail if
they're not).
I then iterate over the JAR to look for a specific file
("filename.extension")
and save the full names of the entry in a Map.
This works like a charm for me, you just need to make sure you add all the
right components in the MOJO.
If anybody needs some more info/help, feel free to ask!
