Mac系统配置Maven时候，按照配置教程，配置完成后，输入mvn -v命令，出现如下错误：

The JAVA_HOME environment variable is not defined correctly
    This environment variable is needed to run this program
    NB: JAVA_HOME should point to a JDK not a JRE

字面意思就是JAVA\_HOME环境变量错误，经发现，博主刚开始配置的路径是jdk1.8.0,但实际安装的是14.0.1，因此修改jdk版本号即可

//JDK路径
    export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-14.0.1.jdk/Contents/Home/
    export PATH=$PATH:$JAVA_HOME/bin
    export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
     
    //Maven路径
    export MAVEN_HOME=export MAVEN_HOME=/Users/xx(Mac电脑用户名)/Desktop/JavaProject/apache-maven-3.6.3
    export PATH=$PATH:$MAVEN_HOME/bin
     
    //Tomcat路径
    export CATALINA_HOME=/Users/xx(Mac电脑用户名)/Desktop/JavaProject/apache-tomcat-9.0.39
    export PATH=$PATH:CATALINA_HOME/bin
