Plugin migration to Maven 3.1+ dependencies

Most important changes:

• switch from Sonatype Aether to Eclipse Aether ( contains a package change in several Maven APIs)
• support of JSR330 in plugins ( javax.inject)

Generating descriptors

For performance, Maven doesn't do classpath scanning. Instead Maven expects a descriptor containing all components.

With Maven 3.1.0+ we can switch from plexus-component-metadata to sisu-maven-plugin

        <plugin>
          <groupId>org.eclipse.sisu</groupId>
          <artifactId>sisu-maven-plugin</artifactId>
          <version>0.3.4</version>
          <executions>
            <execution>
              <id>index-project</id>
              <goals>
                <goal>main-index</goal>
                <goal>test-index</goal>
              </goals>
            </execution>
          </executions>
        </plugin>

Testing

In case org.apache.maven.plugin-testing:maven-plugin-testing is used, it should be changed to 3.1.0 to be Maven 3.1.0 compatible.

PlexusTestcase

In order to make it possible to test with javax.inject in unit tests, one might need to add the following:

    @Override
    protected void customizeContainerConfiguration( ContainerConfiguration configuration )
    {
        configuration.setClassPathScanning( "INDEX" );
    }
