Я могу создать java-программу на ant, и она была правильно настроена. Однако мне интересно, как я могу увидеть System.out.println / System.out.print на консоли с помощью Ant?
Примечание: я не использовал муравей и пытаюсь изучить его. Надеюсь, мой вопрос не глуп?
Простая программа
package antTesting;
public class Helloworld
{
/**
* @param args
*/
public static void main( String[] args )
{
System.out.println( " hello there !!!! " );
}
}
build.xml для того же
