如何在插件中显示jdk.nashorn.api.scripting.JSObject [英] How to make jdk.nashorn.api.scripting.JSObject visible in plugin

问题描述

我有一个与Java脚本交互的Eclipse RCP。现在使用Java 8，使用nashorn，并且必须将依赖于org.mozilla.javascript（插件org.mozilla.javascript_1.7.2.v201005080400.jar）的代码更改为使用jdk.nashorn.api.scripting。

I have an Eclipse RCP that interacts with java script. Now with Java 8, nashorn is used and code that depended on org.mozilla.javascript (plug-in org.mozilla.javascript_1.7.2.v201005080400.jar) must be changed to use jdk.nashorn.api.scripting.

但是当我尝试在Eclipse中使用这个导入时，它没有看到它

But when i try to use this import in Eclipse, it does not see it

import jdk.nashorn.api.scripting.JSObject;

我收到错误：

访问限制：类型'JSObject'不是API（对所需库的限制'< ...> \ jre \lib \\\\\\\\\\\\\\\ b $ b

Access restriction: The type 'JSObject' is not API (restriction on required library '<...>\jre\lib\ext\nashorn.jar')

如何在编译时使它在类路径中可见？

How can I make it visible in the classpath at compile time?

推荐答案

jdk.nashorn.scripting是Nashorn公开的API的一部分。请参阅 https：/ /docs.oracle.com/javase/8/docs/jdk/api/nashorn/jdk/nashorn/api/scripting/JSObject.html

jdk.nashorn.scripting is part of Nashorn's exposed API. Please see https://docs.oracle.com/javase/8/docs/jdk/api/nashorn/jdk/nashorn/api/scripting/JSObject.html

它似乎某些Eclipse特定问题。我用Netbeans 8.0.2编译和编译运行以下应用程序，它按预期编译并运行：

It appears to some Eclipse specific issue. I used Netbeans 8.0.2 to compile & run the following application and it compiled and ran as expected:

package javaapplication2;

import javax.script.*;
import jdk.nashorn.api.scripting.*;

public class JavaApplication2 {
    public static void main(String[] args) throws ScriptException {
        ScriptEngineManager m = new ScriptEngineManager();
        ScriptEngine e = m.getEngineByName("nashorn");
        ScriptObjectMirror sobj = (ScriptObjectMirror)e.eval("({ foo: 33 })");
        System.out.println(sobj.getMember("foo"));
    }
}
