MyEclipse中更换JDK及工程警告问题

告警提示：

Description ResourcePath LocationType

Build path specifies execution environment JavaSE-1.6. There are no JREs installed in the workspace that are strictly compatible with this environment.test Build pathJRE System Library Problem。

解决办法：

MyEclipse8.6默认用自带的JDK，最高版本是1.6，如果想用自己安装的JDK1.7，设置方法：
菜单window--->Preferences--->Java--->Installed JREs，把默认JDK1.6的改为自己新安装的JDK1.7。


这时在java project中会警告：
Description Resource Path Location Type Build path specifies execution environment JavaSE-1.6. There are no JREs installed in the workspace that are strictly compatible with this environment.      communication  Build  path JRE System Library Problem
去除警告方法：工程名称上右键菜单：Properties--->Java Build Path--->Libraries，选中"JRE System Library[JavaSE-1.6]"，选择右侧按钮“Edit"，打开新界面中选择"Workspace default JRR (JDK1.7......)"即可
