When working with the Fuse ESB JBI Maven tooling, you create a top-level project that can build all of the service units and then package them into a service assembly. Using a top-level project for this purpose has several advantages:
It allows you to control the dependencies for all of the parts of an application in a central location.
It limits the number of times you need to specify the proper repositories to load.
It provides you a central location from which to build and deploy the application.
The top-level project is responsible for assembling the application. It uses the Maven assembly plug-in and lists your service units and the service assembly as modules of the project.
Your top-level project contains the following directories:
A source directory containing the information required for the Maven assembly plug-in
A directory to store the service assembly project
At least one directory containing a service unit project
Tip
You will need a project folder for each service unit that is to be included in the generated service assembly.
To use the Fuse ESB JBI Maven tooling, add the elements shown in Example 24 to your top-level POM file.

...These elements point Maven to the correct repositories to download the Fuse ESB Maven tooling and to load the plug-in that implements the tooling.
The top-level POM lists all of the service units and the service assembly that is
generated as modules. The modules are contained in a modules
element. The modules element contains one module element for each service unit in the assembly. You also need a module element for the service assembly.
The modules are listed in the order in which they are built. This means that the service assembly module is listed after all of the service unit modules.
Example 25 shows a top-level POM for a project that contains a single service unit.
