如何解决如何让maven使用已安装的java创建jar文件？

我正在尝试从我的 spring 项目创建一个 jar 文件。我使用命令 mvn package。这些是我的pom.xml-

源和目标已设置为 java 1.8，但是当我使用 java -jar 运行 jar 文件时，出现 UnsupportedClassversion 错误。

我知道这是因为编译项目的 java 版本与我用来运行 jar 文件的版本不同，但我的 java 版本是 1.8.0_51，我也尝试将其作为目标和源pom 文件，结果相同。

JAVA_HOME 和 PATH 变量已设置为正确的目录。

如何配置 maven 使其仅使用已安装的 java？

解决方法

该错误意味着 com/cgny/apm/ApmApplication 是用 Java 16 编译的，因此不能用于 Java 8。

,

编译好的 jar 很好，我刚刚安装了 java 8，它以某种方式覆盖了 JAVA_HOME 和 Path 变量。 java -version 现在显示 16 而不是 1.8。
