No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

1、错误提示:
　　No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

2、原因分析：
　　从翻译可知 Eclipse 不知道是用 JRE 还是使用 JDK 对源码进行编译了；

3、解决办法：
　　eclipse 是使用 JDK 对源码进行编译的，JRE 是字节码的运行环境，无法编译 Java 源码，故我们将配置的 JRE 换成 JDK 即可。
