mvn命令无法在mac OS X Yosmeti上运行

Question

在引用其他堆栈溢出线程和用于安装/配置maven的在线资源之后,我已执行了以下所有必要步骤.这是我做的:

export M2_HOME=/usr/local/apache-maven/apache-maven-3.3.9

export M2=$M2_HOME/bin

我的Java Home变量也设置如下:

echo $JAVA_HOME

/Library/Java/JavaVirtualMachines/jdk1.8.0_60/Contents/Home

export PATH=$M2:$PATH  

尽管如此,当我跑步时mvn --version,我得到了Error: JAVA_HOME is not defined correctly. We cannot execute /Library/Java/JavaVirtualMachines/jdk1.8.0_60/Contents/Home/bin/java.

PATH输出如下:

 echo $PATH
/usr/local/apache-maven/apache-maven-3.3.9/bin:/usr/local/apache-maven/apache-maven-3.2.1/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/git/bin:/usr/local/MacGPG2/bin

Answer 1

export PATH=$M2:$PATH应该是export PATH=$M2/bin:$PATH或export PATH=$M2_HOME/bin:$PATH

JAVA_HOME也应该是这样的

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_60

然后

export PATH=$JAVA_HOME/bin:$PATH

就这样.

一体

export M2_HOME=/usr/local/apache-maven/apache-maven-3.3.9
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_60
export PATH=$JAVA_HOME/bin:$M2_HOME/bin:$PATH
