How to create an Adobe Experience Manager (AEM) project using Archetype?

[JensTi]

We are trying to create a basic AEM Project using the current archetype version 52. Folders and files are created but we receive an error in the groovy post-generation script.

We are using the following command:

mvn -B org.apache.maven.plugins:maven-archetype-plugin:3.3.1:generate \
-D archetypeGroupId=com.adobe.aem \
-D archetypeArtifactId=aem-project-archetype \
-D archetypeVersion=52\
-D appTitle="Test Project" \
-D appId="testproject" \
-D groupId="com.testproject"

This is the error message:

----------------------------------------------------------------------------------------------------------------

Any help is highly appreciated.

Hi @JensTi 

The remote repository seems unable to download resources from new version maven-archetype-plugin:3.3.1. It is still trying to access the older versions 

Can you try using maven-archetype-plugin:3.2.1:generate. Please refer below link

https://github.com/adobe/aem-project-archetype/blob/aem-project-archetype-52/README.md#usage

Hope this helps

Thanks

Hello @PRATHYUSHA_VP ,

yes, it works with maven-archetype-plugin:3.2.1

Thanks for Your help.

Kind Regards,

Jens.
