问题描述
我正在尝试让Oracle的Nashorn在Java 7下运行。
I'm trying to get Oracle's Nashorn running under Java 7.
我克隆了repo并编译了源代码。我需要做的就是编译：
I've cloned the repo and compiled the source. All I had to do to get it to compile was:
- 将jdk.internal.org.objectweb.asm。*更改为org.objectweb .asm。*
- 更改一行有Long.hashCode（）静态的行。
一切似乎都很开心，Java 7将Nashorn视为脚本引擎;但是当我尝试获取一个实例时：
Everything seems happy, and Java 7 sees Nashorn as a scripting engine; but when I try and get an instance:
NashornScriptEngineFactory factory = new NashornScriptEngineFactory();
ScriptEngine engine = factory.getScriptEngine();
我得到例外：
jdk.nashorn.internal.objects.Global在我的类路径中。 Nashorn可能会使用不同的类加载器吗？
jdk.nashorn.internal.objects.Global is in my class path. Does Nashorn use a different class loader maybe?
推荐答案
我试过让它在7之前工作并遇到同样的错误就像你一样。我认为这与Nashorn在Java 8中使用一些新功能这一事实有关。
I tried getting it to work under 7 previously and was met by the same error as you have. I think it has to do with the fact that Nashorn makes use of some new features in Java 8.
有一个 for bitbucket上的JDK 7;我写了一篇博文，详细介绍了如何在我的作品博客上使用它。您还可以查看以获取更多信息。
There is a backport of Nashorn for JDK 7 on bitbucket; I wrote a blog post detailing how to use it on my works blog here. You can also look at this stack overflow question for more information.
该bitbucket项目在一段时间内没有更新，我建议你如果你想和Nashorn一起玩，可以使用的预览。
That bitbucket project hasn't been updated in some time, I'd recommend that you use the preview of Java 8 if you want to play with Nashorn.
