Java mvn compile-[ERROR]此环境中未提供编译器。也许您运行的是JRE而不是JDK？

我正在从命令行运行mvn compile，并得到以下结果：

[ERROR] COMPILATION ERROR :
[INFO] -------------------------------------------------------------
[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?
[INFO] 1 error

我已经看到了这个答案，但它是针对Eclipse的

任何建议

将JDK而不是JRE设置为环境，如有必要，请下载

JDK=JRE+codingstaff，包括一个编译器

将JDK而不是JRE设置为环境，必要时下载它

JDK=JRE+codingstaff，包括一个编译器

您需要更新环境变量，并在ENV变量中给出JDK路径

在这里如何设置

您需要更新环境变量ENV变量中的JDK路径
