This sample project showcases what the maven setup of a typical AEM project could look like. The main focus is on the usage of maven plugins and on inheriting the optional build profiles installBundle and installPackage.

There are lots of comments in the pom files further explain the approach taken.

The project structure is as follows:

aem-sample-project-setup
+- aem-parent
|  +- pom.xml     # the parent pom defines shared plugin configurations
+- bundles
|  +- commons
|  |  +- pom.xml  # an OSGi bundle that could contain utility code
|  +- core
|  |  +- pom.xml  # an OSGi bundle that could contain the core functionality (or a specific feature)
+- package
|  +- pom.xml     # a content-package that embeds the two bundles

Make sure you have the following installed:

• Java 7 or higher (Java 6 may work)
• Maven 3.2.3 or higher (lower versions may work)
• Running AEM 6 instance (other versions should work)

The maven build should run successfully and without side-effects:

mvn clean install

You can install the content-package produced by the build into your local AEM instance (http://localhost:4502 by default):

mvn clean install -P installPackage

To install on a local publish instance (http://localhost:4503):

mvn clean install -P installPackage -Dserver.port=4503

Other parameters can also be used for maximum flexibility, e.g.

mvn clean install -P installPackage -Dserver.url=http://example.local:8080 -Dpassword=secret

To only build the content-package use:

mvn clean install -PinstallPackage -pl package

For more details, take a look at the properties section in aem-parent/pom.xml.

After installing the content-package it is possible to install the bundles individually. This can speed up development when only code in a single bundle is affected. E.g. to install only the core bundle run the following command:

mvn clean install -PinstallBundle -pl bundles/core

Of course it is also possible to install all bundles by running without the -pl option:

mvn clean install -PinstallBundle

Or pick the two bundles you want to build and install

mvn clean install -PinstallBundle -pl bundles/commons,bundles/core
