这是我的pom.xml。当我运行该程序时，我得到如下错误。

Answer 1

无法在以下位置找到Javac编译器：[ERROR] C：\ Program Files （x86）\ Java \ jre6 .. \ lib \ tools.jar [错误]请确保您正在使用 JDK 1.4或以上，[ERROR]不是JRE（com.sun.tools.javac.Main）上课是必需的）。 [错误]在大多数情况下，您可以更改位置通过设置JAVA_HOME环境安装Java [ERROR] 变量

错误表明您使用的是JRE而不是JDK。设置Eclipse / maven以使用JDK，你应该有这个工作。
