问题描述
我尝试从jre6和jdk6升级到jre7和jdk7。
我使用eclipse的程序，我下载并安装了jre7和jdk7：
C：\program files\java\
现在当我进入eclipse我想更改使用的编译器所以我去：
窗口>首选项> java>编译器
但是只出现1.3,1.4,1.5和1.6
我也输入：
window> preferences> java >安装的JRE
并添加了jre7版本。但编译器我不能改变。
如何更改我的eclipse编译器？

推荐答案
您需要升级至少，已经推出了一个多月。另请参见 Eclipse宣布完全支持Java 7。
You need to upgrade to at least Eclipse Indigo SR1, which has been out for over a month. See also Eclipse announces full Java 7 support.
作为证据，这里是我的Indigo SR1偏好设置的屏幕：
