Would be great if it packages the projects as OSGi bundles out of the box.
The following should be sufficient to do it:
```xml
<profile>
<id>Bundle</id>
<activation>
<file>
<!-- NB - this is all the leaf projects, including
logback-* (with no src);
the archetype project neatly ignores this however
-->
<exists>${basedir}/src</exists>
</file>
</activation>
<build>
<plugins>
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<!-- configure plugin to generate MANIFEST.MF
adapted from
http://blog.knowhowlab.org/2010/06/osgi-tutorial-from-project-structure-to.html
-->
<executions>
<execution>
<id>bundle-manifest</id>
<phase>process-classes</phase>
<goals>
<goal>manifest</goal>
</goals>
</execution>
</executions>
<configuration>
<supportedProjectTypes>
<supportedProjectType>jar</supportedProjectType>
</supportedProjectTypes>
<instructions>
<!-- OSGi specific instruction -->
<!--
By default packages containing impl and
internal
are not included in the export list.
Setting an
explicit wildcard will include all
packages
regardless of name.
In time we should minimize our export
lists to
what is really needed.
-->
<Export-Package>brooklyn.*</Export-Package>
</instructions>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifestFile>
${project.build.outputDirectory}/META-INF/MANIFEST.MF </manifestFile>
</archive>
</configuration>
</plugin>
</plugins>
</build>
</profile>
```
Also the brooklyn's parent POM adds an exclusion specifically for m2e,
though I don't get errors even if it is not present:
```xml
<build>
<pluginManagement>
<plugins>
<plugin>
<!-- This configuration is used for Eclipse settings
only. -->
<groupId>org.eclipse.m2e</groupId>
<artifactId>lifecycle-mapping</artifactId>
<version>1.0.0</version>
<configuration>
<lifecycleMappingMetadata>
<pluginExecutions>
<pluginExecution>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<versionRange>[2.3.4,)</versionRange>
<goals>
<goal>manifest</goal>
</goals>
</pluginExecutionFilter>
<action>
<ignore />
</action>
</pluginExecution>
...
```
