分析
java安装正常

>java -versionjava version "1.8.0_381"
Java(TM) SE Runtime Environment (build 1.8.0_381-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.381-b09, mixed mode)>/usr/libexec/java_home -VMatching Java Virtual Machines (3):1.8.381.09 (arm64) "Oracle Corporation" - "Java" /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home1.8.0_381 (arm64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk-1.8.jdk/Contents/Home1.8.0_202 (x86_64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home
/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

mvn -v 查看 runtime 环境

mvn -v
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: /Users/manka/software/apache-maven-3.6.3
Java version: 1.8.0_381, vendor: Oracle Corporation, runtime: /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
Default locale: zh_CN, platform encoding: UTF-8
OS name: "mac os x", version: "14.6.1", arch: "aarch64", family: "mac"

解决

删除掉 JavaAppletPlugin.plugin 这个插件即可。

进入 /Library/Internet Plug-Ins/ 目录，删除 /Library/Internet Plug-Ins/JavaAppletPlugin.plugin

> rm -rf JavaAppletPlugin.plugin

重新执行 mvn -v runtime 正确

 mvn -v
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: /Users/manka/software/apache-maven-3.6.3
Java version: 1.8.0_381, vendor: Oracle Corporation, runtime: /Library/Java/JavaVirtualMachines/jdk-1.8.jdk/Contents/Home/jre
Default locale: zh_CN, platform encoding: UTF-8
OS name: "mac os x", version: "14.6.1", arch: "aarch64", family: "mac"

补充知识
MAC OS X环境的所有配置以及加载顺序如下：

# 系统级别
/etc/profile
/etc/paths # 用户级别
~/.bash_profile 
~/.bash_login 
~/.profile ~/.bashrc（或者~/.zshrc）

前两个环境配置在系统启动时候就会加载，针对所有用户生效，后面四个属于具体用户级别的配置。

Maven会按照以下顺序来确定使用哪个JDK：

Maven配置：Maven允许你通过maven-compiler-plugin插件指定使用的JDK版本。如果你在项目的pom.xml文件中配置了这个插件，并指定了JDK版本，Maven会尝试使用这个版本。
环境变量：如果Maven配置中没有指定JDK版本，它会查找环境变量JAVA_HOME。如果JAVA_HOME被设置，Maven会使用这个环境变量指向的JDK版本。
系统路径：如果JAVA_HOME没有被设置，Maven会退回到系统路径（PATH环境变量）来查找java和javac命令。系统路径中列出的第一个java命令将被使用。
JDK安装：如果系统上安装了多个版本的JDK，并且PATH环境变量中包含了多个JDK的bin目录，那么系统会根据PATH中目录的顺序来决定使用哪个版本的java命令。
系统默认JDK：如果以上都没有指定，Maven将使用系统默认的JDK版本，这通常是操作系统安装时附带的JDK版本。
