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?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。

解决步骤

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),如下图:

在进行maven install的时候,就不会出现该情况了
