Maven, JAVA_HOME is not defined

问题

终端运行 mvn -v

# 原先 JAVA_HOME 配置
$ vim .bash_profile 
export JAVA_HOME=/usr/libexec/java_home
$ source .bash_profile

提示错误信息 :

$ mvn -version
Error: JAVA_HOME is not defined correctly.
We cannot execute /usr/libexec/java_home/bin/java

解决方案 (亲测可用)

对JAVA_HOME进行重新编辑,( )中的为你自己本机javahome的文件路径:

$ vim .bash_profile 

export JAVA_HOME=$(/usr/libexec/java_home)

$ source .bash_profile

再次终端运行 :

$ mvn -v
