问题说明

Eclipse导入Maven项目后，执行 mvn clean install后，出现如下错误：

[INFO] ------------------------------------------------------------------------

大致阅读了一下，说的是执行编译失败，你是不是在JRE环境下运行而不是JDK？闹闹头想了想，JDK已安装、各种环境变量配置木有问题，为什么会出现这种状况呢？寻思了一会儿，知道了原来Eclipse运行是需要一个JRE，而这个JRE并不是系统环境变量中的javac目录下的JRE，而是JDK安装时候自带的JRE目录，此目录下并无javac，故无法进行java的编译，问题找到了，下面说一下具体解决方案。

解决方案

在Eclipse的菜单中，进入 Window > Preferences > Java > Installed JREs > Execution Environments，选择JavaSE-1.x, 在右侧选择JDK的安装目录（注意不要选择JRE的目录）.
no-jdk

然后，进行maven install的时候就会找得到javac了。
