Tutorial on Creating Adobe Experience Manager (AEM) Maven Project Part III

Maven AEM Project Archetype 23 was recently released. To use, set up your local development environment for AEM as a Cloud Service SDK or use one of the following AEM versions: 6.5.0+, 6.4.4.0+ or 6.3.3.4+. Additionally, Java 8 or 11 and Maven 3.3.9+ is also required. Here is an overview of a few of the changes.

Project Generation

The number of prompts for property values when generating the project has been reduced. By default, artifactId will use the appId value and package will use the groupId value. You can change these to use different values if you prefer by adding them to you generate command line.

This is a minimal example for batch mode project generation:

mvn -B archetype:generate \

 -D archetypeGroupId=com.adobe.granite.archetypes \

 -D archetypeArtifactId=aem-project-archetype \

 -D archetypeVersion=23 \

 -D aemVersion=6.5.0 \

 -D appTitle="My Project" \

 -D appId="myproject" \

 -D groupId="com.myproject" \

 -D frontendModule=general \

 -D includeExamples=n
