最近给电脑升级了内存和SSD硬盘，安装好JDK后，之接把免安装的eclipse和代码复制到SSD，mavn clear成功，但是mavn install失败报如下错误：

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

点击eclipse菜单“Window/Java/Installed JREs”发现左侧面板中的jre指向的路径是C:\Program Files\Java\jre1.8.0_261，把其修改为C:\Program Files\Java\jdk1.8.0_261，就一切OK了。
