Я пытаюсь установить leJOS NXJ на мою MAC OS X и запустить его образец, но после того, как я делаю, что он хочет, и экспортировать файл пути NXJ_Home и т. Д. . и установите плагин netbeans и создайте его пример проекта ( Создание собственного проекта с помощью плагина Netbeans ). Я также следую этой структуре и заменяю desire classes.jar из папки lib установки intsall leJOS NXJ.
Я экспортирую эти 4 строки:
My-macbook-pro:~ AR$ export NXJ_HOME=/Users/AR/Documents/Research-kar/JAVA/lejos_nxj
My-macbook-pro:~ AR$ export DYLD_LIBRARY_PATH=$NXJ_HOME/bin
My-macbook-pro:~ AR$ export JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home
My-macbook-pro:~ AR$ export PATH=$PATH:$JAVA_HOME/bin:$NXJ_HOME/binamirrezas-macbook-pro:~ AR$
Это пример кода leJOS NXJ:
package org.lejos.example;
import lejos.nxt.*;
/**
* Example leJOS Project with an ant build file
*
*/
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World");
Button.waitForPress();
}
}
и это связанный файл build.xml:
