Maven构建项目报No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK? 问题的解决方案
在编译SSM项目时,碰到如下问题,希望能给遇到相同问题的小伙伴们帮助 O(∩_∩)O~
Eclipse导入Maven项目后,选中父项目,执行Run AS——>Maven install后,出现如下错误:
说的是执行编译失败,你是不是在JRE环境下运行而不是JDK?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。
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).


配置好之后,选中项目,refresh(或F5)下,重新执行Maven install.本来以为就可以了,还是部分子模块还是报之前的错误。

分析了一下,Maven项目,多模块相互依赖,简单的F5还是不行的,直接Update Maven Project,记得勾选Force Update。

然后在执行Maven install后,这次可以执行成功了。
