When you build your OSGi bundle using Maven -- you can use the following Maven plug-in to automatically deploy the bundle:
<profile>
<id>autoInstallBundle</id>
<build>
<plugins>
<plugin>
<groupId>org.apache.sling</groupId>
<artifactId>maven-sling-plugin</artifactId>
<executions>
<execution>
<id>install-bundle</id>
<goals>
<goal>install</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
</profile>
