docker-manifest-collectosaur-plugin · This plugin is designed to be used in artifacts that generate docker images. babysaur will create a manifest file in artifacts that create docker images and you should use mamasaur in the reactor that controls them. It depends on the "modules" section and will walk down through your POM files looking for submodules of submodules. Given this does not work with Maven when building differences, you should generally NOT use multiple levels of submodules with maven reactors.
