Hi Developers, A new maven module has been created via https://issues.apache.org/jira/browse/AMBARI-24685 to allow us to provide a plugin framework for stack/mpack authors who need to provide their own compiled classes to Ambari. For areas such as upgrade pre-checks and server-side configuration actions, this new SPI module will also be used directly by the ambari-server module for stack-agnostic code which will remain checked into Apache.
Your IDEs may need to include ambari-server-spi now in order to compile correctly.
