我已经在我的机器上安装了 JDK7，我希望将它添加到编译器列表中
I have tried adding JDK 7 in the list of installed JRE but it is still not appearing in the list of compiler compliance level.
我尝试在已安装的 JRE 列表中添加 JDK 7，但它仍然没有出现在编译器合规级别列表中。
Could any one tell me how can I add JDK 7 into new compliance level.
谁能告诉我如何将 JDK 7 添加到新的合规性级别。

Eclipse uses its own compiler (see What is the difference between javac and the Eclipse compiler?), so you won't find it if you use an old version of Eclipse (as probably your RSA is based on). Java 7 support is available for Eclipse 3.7.1 or higher (at the moment current stable is 4.2).
Eclipse 使用它自己的编译器（请参阅javac 和 Eclipse 编译器之间的区别是什么？），因此如果您使用旧版本的 Eclipse（因为您的 RSA 可能基于它），您将找不到它。Java 7 支持可用于 Eclipse 3.7.1 或更高版本（目前稳定版本为 4.2）。
However, if you want to keep that version of Eclipse, you can create a new Builder using your JDK7 as base. To do this, go to Project and add a new Builder specifying where the javac is and the other options.
但是，如果您想保留该版本的 Eclipse，您可以使用 JDK7 作为基础创建一个新的构建器。为此，请转到 Project 并添加一个新的构建器，指定 javac 的位置和其他选项。

Looks like you have to use the 3.8 version of eclipse to get Java 7 support. But I noticed that some later versions of 3.7.x might have it too.
看起来您必须使用 3.8 版本的 eclipse 才能获得 Java 7 支持。但我注意到 3.7.x 的某些更高版本可能也有它。
