无法在NetBeans中导入sun.org.mozilla.javascript.internal

Question

在我的java程序中,我大量使用了Rhino脚本引擎的Suns implmentation.然而,最近,我的JDK在编译时似乎不再自动导入rt.jar文件.

奇怪的是,NetBeans报告了0个实时错误,它们仅在执行完整的清理和构建时出现.在我导入NativeArray之前没有发生这种情况,所以我真的很困惑为什么它突然停止工作.

眼镜:

• 操作系统 - Windows
• Java版本 - java版"1.6.0_20"
• Javac版本 - javac 1.6.0_20
• NetBeans版本 - 6.9

检查它是否存在:

C:\Documents and Settings\LordQuackstar\Desktop\TestApp\src>javap sun.org.mozill
a.javascript.internal.WrappedException
Compiled from "WrappedException.java"
public class sun.org.mozilla.javascript.internal.WrappedException extends sun.or
g.mozilla.javascript.internal.EvaluatorException{
    static final long serialVersionUID;
    public sun.org.mozilla.javascript.internal.WrappedException(java.lang.Throwa
ble);
    public java.lang.Throwable getWrappedException();
    public java.lang.Object unwrap();
}

好吧它存在,所以这里是一些测试代码:

package testapp;

import sun.org.mozilla.javascript.internal.WrappedException;

public class Main {
    public static void main(String[] args) {
        WrappedException e = new WrappedException(null);
    }
}

Netbeans输出:

那么什么会导致这种情况突然失败？昨天工作得很好.除了从同一个包中导入另外两个类之外,我没有改变任何东西.我的所有依赖项都没有改变.

将在linux中测试,看看问题是否仍然存在.

在你说之前:不,我不是分开下载rhino,不,我不是在改变IDE,

有两种迹象表明你不应该使用这个类:sun并且internal- 这意味着这是一些不应被第三方使用的内部类.因为它可以在将来的版本中更改或删除 - 即这不是API的一部分.所以 - 单独下载Rhino.

如果您使用脚本API - 仅使用API​​类/接口 - 即 javax.script
