如何在Java 7中使用org.json Java库

我需要在我的应用程序中进行一些简单的JSON解析， Douglas Crockford库似乎正是我所需要的。

I need some simple JSON parsing in my application and the Douglas Crockford library seems exactly what I need.

但是，我似乎遇到了问题。我收到以下错误：

However, I seem to be running into a problem. I'm getting the following error:

线程main中的异常java.lang.UnsupportedClassVersionError：org / json / JSONObject：不支持的major。次要版本52.0

我搜索了一下，我得到的印象是这是由于某些版本不兼容。我试过改变Java版本，但似乎没有帮助。我在我的程序中使用Java 7和Java 7功能，最终我想使用Java 7.

I Googled around a bit and I get the impression that this is due to some version incompatibility. I've tried changing Java versions but it doesn't seem to help. I'm using Java 7 and Java 7 features in my program and ultimately I want to use Java 7.

如何解决此问题？

PS：我看过Jackson和GSON，绝对不想使用它们，所以请不要建议作为替代。

PS: I looked at Jackson and GSON and definitely don't want to use either so please don't suggest as an alternative.
