How to get local repository location (URI) from within Maven 3.x plugin? Use Aether as described in this blog post . /** * The current repository/network configuration of Maven. * * @parameter default-value="${repositorySystemSession}" * @readonly */ private RepositorySystemSession repoSession; now get the local Repo through RepositorySystemSession.getLocalRepository() : LocalRepository localRepo = repoSession.getLocalRepository(); LocalRepository has a getBasedir() method, which is probably what you want. This one worked for me in Maven v3.6.0: @Parameter(defaultValue = "${localRepository}",

I would create programmatically the effective model from a pom file to get all inherited attributes in the pom model instance. I would analyze some attributes of a pom - but I need for it all attributes - incl. inhertied. What have I to do? I have tried Sonatype Aether but I did not find a example. Check out this Gist https://gist.github.com/reiz/6203767 . It shows a method which builds a MavenProject inside of a maven plugin. On the MavenProject you can call methods like project.getDependencies() and so on. You could just run mvn help:effective-pom to get the pom that maven is actually using,

The 3.1.0 release of Maven relies on Eclipse Aether (org.eclipse.aether) instead of Sonatype Aether (org.sonatype.aether). This seems to break compatibility for plugins relying on Sonatype aether : try running such plugins and you'll run into : java.lang.NoClassDefFoundError: org/sonatype/aether/* Caused by: java.lang.ClassNotFoundException: org.sonatype.aether.* As documented in https://cwiki.apache.org/confluence/display/MAVEN/AetherClassNotFound Now, is it possible to make a mojo relying on aether classes (such as org.sonatype.aether.RepositorySystemSession) run both with Maven 3.0.x and

Maybe this is going to be a larger task than I had originally thought, but regardless, I'm trying to load a MavenProject from a file and then resolve its dependencies. I've got the code for both bits but I'm missing some object references that I need; specifically I need to get instances of RepositorySystemSession and RepositorySystem . Any tips? Note: I have tagged this question with maven-plugin , but this is not a Maven plugin. I am happy to mandate Maven 3 (think I already have anyway..) Here's the code I have so far: Constructing the MavenProject : public static MavenProject loadProject

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.

I am using the maven indexer to fetch the maven index from the maven central repository. Since I updated from org.sonatype.aether to org.eclipse.aether and from maven 3.0.5 to maven 3.1.0 I am getting this Exception.
