Writing a Consumer Plugin

 For a sample custom consumer, you can checkout the archiva-consumer-plugin at the archiva sandbox in the SVN repository:

+----+
http://svn.apache.org/repos/asf/archiva/sandbox/archiva-consumer-plugin
+----+

 Below are the steps on how to create a custom repository consumer and plug it in Archiva:

 [[1]] Create a project for your component.

 [[2]] Declare your class or in this case, consumer as a component as shown in the example below. This
   should be put at the class level.

+----+
Ex.
@plexus.component role="org.apache.maven.archiva.consumers.KnownRepositoryContentConsumer"
                  role-hint="discover-new-artifact"
                  instantiation-strategy="per-lookup"

where,
  role: the interface that your class implements
  role-hint: the lookup name of the component (your class/consumer)
  instantiation-strategy: how your class will be instantiated
+----+

 [[3]] Make sure to add the snippet below in the <build> section of the project's pom. This is needed to
   generate the components.xml.

+----+
<plugin>
  <groupId>org.codehaus.plexus</groupId>
  <artifactId>plexus-maven-plugin</artifactId>
  <version>1.3.5</version>
  <executions>
    <execution>
      <id>generate</id>
      <goals>
        <goal>descriptor</goal>
      </goals>
    </execution>
  </executions>
</plugin>
+----+

 [[4]] Package your project by executing 'mvn clean package'

 [[5]] Let's say you are using the apache-archiva-1.0-bin.tar.gz to run Archiva. Unpack
   the binaries then go to bin/linux-x86-32/ (assuming you are running on Linux), then execute
   './run.sh console'. Then stop or shutdown Archiva after it started. (This is necessary to unpack
   the war file.)

 [[6]] Copy the jar file you created in step 4 in apache-archiva-1.0/apps/archiva/webapp/lib/

 [[7]] Add the necessary configurations in archiva.xml (in this case, add 'discover-new-artifact' as a
   <knownContentConsumer>)

 [[8]] Start up Archiva again.
