Create Multiple Bundles in an AEM Maven Project

In AEM, Maven provides multi-module architecture.

What does it mean?

It means that we can have different modules like bundles and content(core,ui.apps) in a single project.

In this blog, we will discuss how can we create multiple bundles in the same project.

Initially, when we create an AEM Project, we always see two modules:

1. Bundle
2. Content

These modules are defined under parent Pom.xml.

Problem Statement: I want to create multiple bundles in the same AEM Project. The use cases of doing this can be:

• Need a bundle to run in publish instance only or need to deploy a bundle on the basis of specific locations.
• Want to create multiple bundles in a single project on the basis of big functionalities like Login Module, Payment Module, etc.

Solution: It is very easy, you just need to follow the below steps:

• Create the new bundle by just copying the existing bundle of a project.

• Rename the bundle1 ( i.e., test). Now In Pom.xml of Test bundle change the ArtifactID (Because artifact should be unique for each module of the project).

• Change the “Bundle-SymbolicName”  in the Test Module Pom.xml.

• Add a new module in parent Pom.xml.

• Content Pom.xml  contains the dependency of all the bundles, so we need to add the dependency of the new bundle(test-module) in this Pom.xml

• For deploying the bundles at any specific location we need to specify the location in the "target" (like install) and bundle ‘s groupId and artifactid in the embedded section.

• Now you just need to build the code and you can find the bundle’s jar at the expected location as you configured in content Pom.xml in embedded section.

By following the above steps you can create n number of bundles in a single AEM project.
