访问限制：“应用程序”类型不是API（对所需库rt.jar的限制）

Question

这是代码：

package mscontroller;

import javax.swing.*;

import com.apple.eawt.Application;

public class Main {

    public static void main(String[] args)

    {

        Application app = new Application();

        app.setEnabledAboutMenu(true);

        AMEListener listener = new AMEListener();

        app.addApplicationListener(listener);

        JFrame mainFrame = new JFrame("Application Menu Example");

        mainFrame.setSize(500, 500);

        mainFrame.setVisible(true);

    }

}

这是错误：

Exception in thread "main" java.lang.Error: Unresolved compilation

problems:   Access restriction: The type 'Application' is not API

(restriction on required library

'/Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Home/jre/lib/rt.jar')

    Access restriction: The constructor 'Application()' is not API

    Access restriction: The type 'Application' is not API (restriction on

    Access restriction: The method

'Application.setEnabledAboutMenu(boolean)' is not API (restriction on

required library

    AMEListener cannot be resolved to a type    AMEListener cannot be

resolved to a type

    at mscontroller.Main.main(Main.java:9)

eclipse说这个：

访问限制：“应用程序”类型不是API（对必需库'/Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Home/jre/lib/rt.jar'的限制）

我遇到了同样的问题。当我最初在Eclipse中创建java项目时，我指定了JRE 8.当我进入项目的构建路径并编辑JRE系统库时，选择了Java 8执行环境。当我选择使用“Alernate JRE”（仍然是java 8）时，它为我修复了错误。

在eclipse氧气中添加javafx可访问权限转到项目>属性> java构建路径>库>然后展开库并双击>访问规则，在那里设置权限解决方案：可访问规则模式：javafx / **
