Maven plugin for dependency resolution

[Marek Psiuk <ma...@agh.edu.pl>]

Hello,

I am working on a maven plugin which is supposed to write a list of
dependencies (all dependencies, also transitive ones) of the current
artifact to the file. All those dependencies are OSGi bundles which are
used in the following step in a pax runner to launch OSGi environment. I
found aether and managed to write simple POC which lists dependencies that
I need. However I have the following problem. I want my plugin to be usable
in both maven-2.x and maven-3.x and I cannot force aether to work in
maven-2.x.
Is there some uniform way of getting all transitive dependencies of the
current artifact which would be compatible with both maven-2.x and
maven-3.x?

For now I figured out that I can built separate JAR artifact which
assemblies all needed depedencies (aether and others) and then simply do:
    Process p = Runtime
    .getRuntime()
    .exec("java -jar artifact.jar-with-dependencies.jar");

Yeah I know that it's ugly but it works :]. Another workaround would be to
also have this separate JAR and jail it in my own classloader - not that
hard to do.

Anyway I cannot figure out straighforward solution.

I would be thankful for any help.


Kind Regards,

Marek Psiuk

Hi Karl,

thanks for help.
Yes I spotted this depedency-plugin and managed to write simple POC which
works (to some extent).

The thing is that I wanted also to sort of "run" my plugin from standalone
java application (Eclipse -> Run As -> Java Application). Aether is great
for such kind of things. I wonder if You could point me to a source which
tells how to run maven-2 plugins ... outside of maven.


Kind Regards,

Hi,

have you taken a look into the maven-dependency-plugin code ? This works as
well in M2 as well in M3 ...

Aether is intended only for M3 world...within a plugin you can get the
Dependencies via:

this.project.getArtifacts();

if you inject the MavenProject on your plugin parameters:

/**
* The Maven project.
*
* @parameter expression="${project}"
* @required
* @readonly
*/
    protected MavenProject project;


Take a look at:

Or take a look at the Maven-dependency-plugin...code...might be a better
place...

Kind regards
