Java Module jdk.compiler Package com.sun.source.util Interface Plugin（JDK11）

The javac plug-in mechanism allows a user to specify one or more plug-ins on the javac command line, to be started soon after the compilation has begun. Plug-ins are identified by a user-friendly name. Each plug-in that is started will be passed an array of strings, which may be used to provide the plug-in with values for any desired options or other arguments.

Plug-ins are located via a ServiceLoader, using the same class path as annotation processors (i.e. ANNOTATION_PROCESSOR_PATH or -processorpath).

It is expected that a typical plug-in will simply register a TaskListener to be informed of events during the execution of the compilation, and that the rest of the work will be done by the task listener.
