ACS (Adobe Consulting Services) AEM Commons is an open-source library of pre-built AEM tools and functionalities that can help editors and developers to perform different operations on AEM servers, from deployment to cache management.
Operations done with ACS Commons can often be performed in other ways, however there are some advantages in using ACS Commons tools. For example a lot of operations can be done by simply going in the right ACS Commons page and set the needed configurations.
ACS Commons come in one package that can be installed on the AEM server in two ways:
1. embedding ACS Commons in the AEM project as a Maven dependency,
2. manually deploying the ACS Commons package with package manager.
The package contains all ACS Commons tools, so it’s not possibile to install only the needed features.
