helloworld.java

利用ant进行java编程的例子

package src;

import org.apache.tools.ant.Task;
import org.apache.tools.ant.BuildException;


public class HelloWorld extends Task {
	String message;
    public void setMessage(String msg) {
        message = msg;
        System.out.println(message);
    }

    public void execute() {
        // use of the reference to Project-instance
        String message1 = getProject().getProperty("ant.project.name");

        // Task's log method
        log("Here is project '" + message1 + "'.");

        // where this task is used?
        log("I am used in: " +  getLocation() );
        
        if (message==null) {
            throw new BuildException("No message set.");
        }
        log(message);

    }
}
