# antRunner application entry point

The Ant core plugin declares a main entry point that allows the running of Eclipse's integrated Ant support in a headless environment. An Ant build can then be run directly from the main platform launcher.

This is an example .bat file that shows how to make use of the antRunner application entry point on Windows.
