Re: [mojo-dev] Question: Installing artifacts from within reactor

[Robert Scholte]

Have a look at the invoker:install, looks like it is doing the same thing.

Hi,
i'm currently trying to solve a problem, which i don't understand:

I have the following code:

     /**
      * The project currently being build.
      */
     @Component
     private MavenProject mavenProject;

     /**
      * The current Maven session.
      */
     @Component
     private MavenSession mavenSession;

     @Component
     private ArtifactResolver artifactResolver;

     @Component
     protected ArtifactRepositoryFactory artifactRepositoryFactory;

     @Component( role = ArtifactRepositoryLayout.class )
     private Map<String, ArtifactRepositoryLayout> repositoryLayouts;

     @Component
     private ArtifactInstaller artifactInstaller;

     @Parameter( property = "localRepository", required = true, readonly  
= true )
     protected ArtifactRepository localRepository;

     public void execute()
         throws MojoExecutionException
     {
         ArtifactRepository targetRepository =
 artifactRepositoryFactory.createDeploymentArtifactRepository( "local",  
getFolder().toURI().toString(),
     repositoryLayouts.get( "flat" ), false /* uniqueVersion */);

         ProjectDependencyGraph projectDependencyGraph =  
mavenSession.getProjectDependencyGraph();
         List<MavenProject> sortedProjects =  
projectDependencyGraph.getSortedProjects();

         for ( MavenProject sortedMavenProject : sortedProjects )
         {
             getLog().info( "---> " + sortedMavenProject.getId() );
             Artifact artifact = sortedMavenProject.getArtifact();
             try
             {
                 artifactInstaller.install( artifact.getFile(),  
artifact, targetRepository );
             }
             catch ( ArtifactInstallationException e )
             {
                 getLog().error( "Error during installation of  
artifacts", e );
             }
         }
     }

The problem i have is during the following code:

artifactInstaller.install( artifact.getFile(), artifact,  
targetRepository );

artifact.getFile() is null, cause the artifact is comming from the  
reactor. In this case i need to access the artifacts based on the  
sortedProjects list.

So the question is: How can i use an artifact which is within the  
reactor and how can i install (copy) this artifact to a particular  
location without the aboved described problem?

Apart from that is it possible to control if maven-metadata-local.xml is  
installed into that repository or not?

Thanks in advance.

Kind regards
Karl-Heinz Marbaise
