Abstract

AEM Developers, Infrastructure Engineers regularly come across a challenge on building the AEM code & dispatcher module use to get failed while mvn build. The article addresses in a simple way on how to understand the mechanisms of dispatcher module build, and gives a detailed explanation of how it can be resolved.

This is use full for building the code for a deployment via Pipeline either it is Adobe Cloud manager or Jenkins.
This error is caused as the dispatcher owner does not not want you to change/modify few of its default files which are marked as immutable in dispatcher server.
You can find full list of immutable files on of dispatcher provided by Adobe.

Issue :- In AEM while doing the deployment it is being seen , user get the exception , Maven mandatory check failed.

Solution :- To make sure you do not modify the default files the maven dispatcher module forces the file checksum verification method.

All these checksum values can be find in the.
