当我执行mvn -version时，我收到以下错误消息仅供参考： - 我看到其他相关帖子，但没有一个能解决我的问题

我的bash个人资料设置如下：

export JAVA_HOME=/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
export M2_HOME=/Users/ashvithavenkateshkumar/Downloads/apache-maven-3.3.9
export PATH=$PATH:$M2_HOME/bin

有人可以看看这里出了什么问题。

如果路径以JAVA_HOME = / Library / Java / JavaVirtualMachines / jdk1.6.0_65.jdk / Contents / Home给出，我也会收到错误java home not found 但如果我给出JAVA_HOME = / Library / Java / JavaVirtualMachines / 1.6.0.jdk / Contents / Home那么它可以正常工作。（区别在于我删除了版本前面的_65和jdk）

maven安装设置bash配置文件
