Retrieving Maven Artifact from Repository using Maven Java API


If I have a Maven Artifact information (GroupId, ArtifactId, Version) how can I programmatically (using Java) retrieve that Artifact from my local repository?

Specifically, I need to be able to connect to the Maven Repository and create/retrieve a org.apache.maven.artifact.Artifact so I can retrieve the file associated with the Artifact.

I have looked into m2e source code, but the MavenImpl.java (which provides Artifact resolution) is way more complex than what I need and it is difficult to understand how the connection to the repository works.


Solution

  • You'll probably want to look at Aether. See the Wiki for examples.
