随机“没有编译器提供”错误Maven

Question

我尝试使用maven构建项目。每次我可以不小心收到错误

No compiler is provided in this environment. perhaps you are running on a jre rather than a jdk? 

而且我可以再次运行生成，一切都很好。

我有这样的错误使用CMD（MVN封装）和使用Eclipse（Maven构建）的约40％

解决的90％：

下载最新的JDK，更新JAVA_HOME，更新Window->Preferences->Java->Installed JREs

Answer 1

如错误所示，您在jre上运行它，请选择您的jdk路径。

窗口 - >首选项 - > Java的>安装JREs-> jre1.8.0_40

你应该有一个JDK有一个条目。如果没有指向JDK。

然后，

右击项目 - >的Maven - >更新项目

Answer 2

安装JDK并设置JAVA-HOME到你的JDK路径。
