I'm attempting to follow the iPOJO tutorial¹ 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
`----
