Resolve dependencies inside a Nexus Plugin

[Oscar Picasso-4]

Hi,

I am writing a Nexus Plugin that would record all the transitive dependencies of any deployed artifact. I have some trouble to get the dependencies properly resolved.

Here are the pending problems I have:

1. It does not resolve always to the latest SNAPSHOT dependencies. 
2. I don't see how to get dependencies that have a classifier.
3. How to get the scope of a dependency like when you use mvn dependency:tree?

I have tried different things. The closer to what I want is like code below, but this does not solve the problems above.

GavCalculator calculator = mavenRepository.getGavCalculator();

Gav gav = calculator.pathToGav(path);

Dependency dependency = Utils.createDependencyFromGav(gav, null);

CollectRequest collectRequest = new CollectRequest(dependency,

repositories);

DependencyRequest dependencyRequest = new DependencyRequest(

collectRequest, null);

DependencyResult result = getRepositorySystem()

.resolveDependencies(getRepositorySession(), dependencyRequest);

List<ArtifactResult> artifactResults = result

.getArtifactResults();

Any pointer?

At this stage point 1 is the more important.

Buenas Oscar

mavenRepository?
repositories?
getRepositories()?
getRepositorySession()?
nexus-indexer version?

Saludos!

Hi Martin,

Below refactored code that also show the details. Take note that getRepositories() was a copy/paste mistake in my first email. The real resolveDependencies call is in the code below.

@Named

public class DeployRecorder2 extends ComponentSupport implements

EventSubscriber {

private final NexusAether nexusAether;

private final RepositoryRegistry repositoryRegistry;

@Inject

public DeployRecorder2(final NexusAether nexusAether,

final RepositoryRegistry repositoryRegistry) {

this.nexusAether = checkNotNull(nexusAether);

this.repositoryRegistry = checkNotNull(repositoryRegistry);

}

@Subscribe

public void onDeployEvent2(RepositoryItemEventStoreCreate event)

throws Exception {

final StorageItem item = event.getItem();

final String path = item.getPath();

if (item instanceof StorageFileItem && path.endsWith(".pom")) {

MavenRepository mavenRepository = (MavenRepository) event

.getRepository();

GavCalculator calculator = mavenRepository.getGavCalculator();

Gav gav = calculator.pathToGav(event.getItem().getPath());

Dependency dependency = Utils.createDependencyFromGav(gav, null);

// building repository list, "public" is a nexus repository group

List<RemoteRepository> repositories = new ArrayList<>();

Repository repository = repositoryRegistry.getRepository("public");

M2GroupRepository repoGroup = (M2GroupRepository) repository;

List<Repository> members = repoGroup.getMemberRepositories();

for (Repository member : members) {

repositories.add(new RemoteRepository(member.getId(),

"default", repository.getLocalUrl()));

}

CollectRequest collectRequest = new CollectRequest(dependency,

repositories);

DependencyRequest dependencyRequest = new DependencyRequest(

collectRequest, null);

DependencyResult result = nexusAether.getRepositorySystem()

.resolveDependencies(

nexusAether.getDefaultRepositorySystemSession(),

dependencyRequest);

List<ArtifactResult> artifactResults = result.getArtifactResults();

// / etc.

}

}

}

Regards

Oscar
