[aether-users] How to download an artifact from a Maven repository using aether

Hello All,

 

I’m new to Eclipse Aether and I wonder if is possible to download artifacts from a remote repository, similar to maven dependency:get (http://maven.apache.org/plugins/maven-dependency-plugin/get-mojo.html); So far I figured how to get the latest version of an artefact from a remote repository and I guess I need to use install to get a copy on the local repository:

 

Version newestVersion = rangeResult.getHighestVersion();            

Artifact newestArtifact = new DefaultArtifact(artifact.getGroupId(), artifact.getArtifactId(), artifact.getClassifier(), artifact.getExtension(), newestVersion.toString());

Artifact pomArtifact = new SubArtifact(newestArtifact, "", "pom");

InstallRequest ins = new InstallRequest();

ins.addArtifact(newestArtifact).addArtifact(pomArtifact);

system.install(session, ins);

 

But it seems than I’m missing some glue to tell my client to fetch it from the remote repository:

 

INFO: Installing XXX:YYY.jar:jar:ZZZZ-PRODUCTION to C:\projects\.m2 (enhanced)

INFO: Installed XXX:YYY.jar:jar:ZZZZ-PRODUCTION to C:\projects\.m2 (enhanced)

Exception in thread "main" org.sonatype.aether.installation.InstallationException: Failed to install artifact XXX:YYY.jar:jar:ZZZZ-PRODUCTION: null

      at org.sonatype.aether.impl.internal.DefaultInstaller.install(DefaultInstaller.java:279)

      at org.sonatype.aether.impl.internal.DefaultInstaller.install(DefaultInstaller.java:201)

      at org.sonatype.aether.impl.internal.DefaultInstaller.install(DefaultInstaller.java:158)

      at org.sonatype.aether.impl.internal.DefaultRepositorySystem.install(DefaultRepositorySystem.java:436)

 

Is this something that Aether can do or should I look to the Maven API directly? If so, does anybody know where to look?

 

Thanks in advance,

 

--Jose
