JAVA_HOME路径未指向正确的路径

如何解决JAVA_HOME路径未指向正确的路径

我正在使用VPN环境编写代码。一切正常，但是现在我无法执行maven命令。

我得到的错误是：

NB: JAVA_HOME should point to a JDK not a JRE

现在，当我运行以下命令时：%JAVA_HOME%我得到以下消息：C:\Program Files\apache-maven-3.6.3\bin而不是C:\Program Files\Java\jdk1.8.0_251

正在运行：java -XshowSettings:properties version

Java_Home路径似乎是一个管理员设置，我无法更改自己。那么，对于我来说，有什么我可以解决的问题吗？

解决方法

更改了

环境变量

希望问题会得到解决

新系统变量

在我的情况下，看起来像

您可以覆盖JAVA_HOME变量，在Maven脚本文件中对其进行设置。

为此，请编辑mvn.cmd并将以下行添加到文件的开头：

set JAVA_HOME="C:\Program Files\Java\jdk1.8.0_251"

将jdk物理路径添加到环境变量。应该可以解决问题
