Mac下配置Maven

1.Java环境变量设置就不说。 但是配置Maven需要检查下Java环境变量的设置。需要检查JAVA_HOME环境变量以及Java命令

wanyakundeMacBook-Pro:Library wanyakun$ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.7.0_60.jdk/Contents/Home
wanyakundeMacBook-Pro:Library wanyakun$ java -version
java version "1.7.0_60-ea"
Java(TM) SE Runtime Environment (build 1.7.0_60-ea-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode)
wanyakundeMacBook-Pro:Library wanyakun$ 

2.接着到http://maven.apache.org/download.html下载Maven安装文件，如apache-maven-3.2.3-bin.tar.gz，然后解压到本地目录

接下来，我们需要设置M2_HOME(IntelliJ默认为M2_HOME)环境变量指向apache-maven-3.2.3，并且把Maven安装目录下的bin/文件夹添加到系统环境变量PATH中去：

vim打开/etc/profile文件 加入如下代码：    

export M2_HOME=/Users/wanyakun/Documents/apache-maven-3.2.3

export PATH=$PATH:$M2_HOME/bin

至此，安装完成，我们可以运行以下命令检查Maven安装：

 echo $M2_HOME

 mvn –version

wanyakundeMacBook-Pro:~ wanyakun$ echo $M2_HOME
/Users/wanyakun/Documents/apache-maven-3.2.3
wanyakundeMacBook-Pro:~ wanyakun$ mvn -version
