Maven项目build时出现No compiler is provided in this environment的解决方法

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

错误代码节选:

[ERROR] COMPILATION ERROR :

[INFO] 1 error

解决方法：

        看Eclipse-->Window-->preferences-->Java-->Installed JREs

如果你打开后已经选中了jdk则不需要处理，如果是jre的话，就点击add

点击next，选择你的jdk的位置，最后finish

最后选中jdk,下面的jre也可以删掉

我们看看Maven的环境是如何配置的:先找到Eclipse-->Window-->preferences-->Maven-->Installations

 

在Maven配置中, 我并没有使用Eclipse自带的Maven插件, 而是重新配置的Maven环境, 然后再看Eclipse-->Window-->preferences-->Maven-->User Settings

 

Maven设置使用的是Maven中conf文件夹下的settings.xml

在180行左右的profiles标签内加入这么一段话

      jdk-1.8
      
        true
        1.8
      
      
        1.8
        1.8
        1.8
      

在项目上右键Build Path，进入

然后再编译运行项目即可.
