Build the bundle and deploy it to the releases repository. Here's a reminder of the build and deploy command:
mvn clean deploy
...
[INFO] Deploying file:/C:/projects/felixbook/releases/com/packtpub/felix/com.packtpub.felix.bookshelf-service/1.7.0/com.packtpub.felix.bookshelf-service-1.7.0.jar
[INFO] Writing OBR metadata
[INFO] Uploading repository.xml
[INFO] UNLOCK file:///C:/projects/felixbook/releases/repository.xml
[INFO] ----------------------------------------------------------------------
[INFO] BUILD SUCCESSFUL
If the build is successful, the bundle will be deployed to the releases repository and the OBR repository file will be updated. Next, we install the bundle to Felix.
