how to obtain maven effective dependencies from an external pom ?

[myannou]

Hello,

I am developping a plugin in which I would like to analyse all current maven depdencies and compare them to all dependency from an external pom.

For this I need to obtain all effective dependencies of the external pom, but how could I do it in a Forge plugin ?

What I did, I changed the current pom parent to, temporaly, replace the parent with the external pom then save it, so that I can use the dependencyFacet.getEffectiveDependencies() method :

 Model pom = mvn.getPOM();
  Model backupPom = pom.clone();
  update = changePomParent(out, currentParent, update, depParentOfficial, lastVersion, pom);
  if (update) {
  mvn.setPOM(pom);
  }
  DependencyFacet dependencyFacet = project.getFacet(DependencyFacet.class);
  officialDeps = dependencyFacet.getEffectiveDependencies();
  if (update) {
  mvn.setPOM(backupPom);
  }

But, as you can guess, it is not really a good solution because:

- I have to change the current pom

- and it add the dependencies of the current pom

Thanks for your help

Hi Yann,

Have you tried to @Inject ProjectFactory in your plugin and use it to find your external pom.xml as a new Project ? Then you could call getEffectiveDependencies() on each project object to compare dependencies.

Hi George,

I just tried, it works if my file is in the local repo but in the case where this pom.xml is not (yet) in the local repo then I cannot do a reference on this file.

Or should I use the remote repo to locate this file ? is this going to work with the ProjectFactory API ?

Thanks

Yann.

Hi Yann,

Have you tried @Inject DependencyResolver for this task ?

With that you can call resolveDependencies or resolveDependencyMetadata.

I think this is what you're looking for.
