- Support Java 9, 10, and 11.
- Fix an ExceptionInInitializerError when plugin is used on Java 11 (401)
Integrates revamped support for authentication from docker-client into the plugin, making it possible for the plugin to be more flexible in regards to authentication credentials used when pushing/pulling/building images.
Previous versions of the plugin had the limitation of using the same RegistryAuth header for all images, regardless of what registries they came from.
In this version, the docker-maven-plugin will automatically use any
authentication present in the docker-cli configuration file at ~/.dockercfg
or ~/.docker/config.json.
Additionally the plugin will enable support for Google Container Registry if it
is able to successfully load Google's "Application Default Credentials".
The plugin will also load Google credentials from the file pointed to by the
environment variable DOCKER_GOOGLE_CREDENTIALS if it is defined. Since GCR
authentication requires retrieving short-lived access codes for the given
credentials, support for this registry is baked into the underlying
docker-client rather than having to first populate the docker config file
before running the plugin.
Lastly, authentication credentials can be explicitly configured in your pom.xml
and in your Maven installation's settings.xml file as part of the
<servers></servers> block.
