Magnolia 6.0 reached end of life on June 26, 2019. This branch is no longer supported, see End-of-life policy.
A module descriptor is a Magnolia-specific file that identifies and defines the module.
src/main/resources/META-INF/magnolia/<module-name>.xml
.$magnolia-resources.dir/<module-name>/module.yaml
.Please be aware that the YAML-based file does not support all features which are possible with the XML-based module descriptor. For more details please have a closer look at the detail pages.
