export MAVEN_HOME=/Users/lcc/soft/maven/apache-maven-3.5.4
export PATH=$PATH:$MAVEN_HOME/bin
執行mvn命令查詢
lcc@lcc ~$ mvn -version

然後報錯
發現還是使用老的，然後查看一下
lcc@lcc ~$ ll /usr/local/bin/mvn
lrwxr-xr-x 1 lcc admin 48 Jun 24 14:47 /usr/local/bin/mvn@ -> /usr/local/Cellar/maven/3.5.0/bin/mvn
還是指向老的
改下就可以了
lcc@lcc ~$ ll /usr/local/bin/mvn
lrwxr-xr-x 1 lcc admin 48 Jun 24 14:47 /usr/local/bin/mvn@ -> /Users/lcc/soft/maven/apache-maven-3.5.4/bin/mvn
