Subject Problem trying to use iPOJO Maven plugin
Date Thu, 01 Mar 2007 18:42:00 GMT
I'm attempting to follow the iPOJO tutorial┬╣ in creating an
iPOJO-managed bundle. Specifically, I'm trying to define a factory
component inside this bundle.

The POM declares a packaging-type of "ipojo-bundle". There's an iPOJO
metadata file called "metadata.xml" available at the root of the JAR's
resource directory.

The plugin configuration element is as follows, using version
0.7.0-incubator-SNAPSHOT of the plugin:

      <plugin>
        <groupId>org.apache.felix</groupId>
        <artifactId>org.apache.felix.ipojo.plugin</artifactId>
        <extensions>true</extensions>
        <configuration>
          <osgiManifest>
            <bundleName>${pom.name}</bundleName>
            <bundleDescription>${pom.description}</bundleDescription>
            <!--<exportPackage></exportPackage>-->
            <!--<ipojoMetadata>metadata.xml</ipojoMetadata>-->
          </osgiManifest>
        </configuration>
      </plugin>

I assumed that most of these values would have sensible defaults like
the maven-bundle-plugin. Uncommenting the ipojoMetadata element fails
during "mvn package" with this error:

,----
| org.codehaus.plexus.component.configurator.ComponentConfigurationException:
| Cannot find setter nor field in
| org.apache.felix.ipojo.plugin.OsgiManifest for 'ipojoMetadata'
`----

When I comment that element out and trust the default, I see the
following error:

,----
| org.apache.maven.plugin.MojoExecutionException:
| [iPOJO] Neither iPOJO-Metadata nor iPOJO-Components are in the manifest
`----

Are there some other steps I need to follow to get this to work?
