mac 配置jdk maven

1.从oracle下载jdk

链接：http://www.oracle.com/technetwork/java/javase/downloads/index.html

然后安装jdk

2.下载Maven，链接：http://maven.apache.org/download.cgi  

这里有好几种格式，比如下载apache-maven-3.3.9-bin.zip，将改压缩文件解压到自己的文件夹路径中，如

/Users/apple/tools/apache-maven-3.3.9

3.配置环境变量：打开mac的终端： Finder－>应用程序－>实用工具－>终端

／／查看java版本

appledeMacBook-Air:note apple$ java -version
java version "1.8.0_77"

／／打开系统配置文件，渐入密码

appledeMacBook-Air:note apple$ sudo vim /etc/profile
Password:＊＊＊＊＊＊

／／在最后一行，插入jdk和maven的环境配置信息

JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.8.0_77.jdk/Contents/Home/"

CLASS_PATH="$JAVA_HOME/lib"

MAVEN_HOME=/Users/apple/tools/apache-maven-3.3.9

PATH=".;$PATH:$JAVA_HOME/bin" 

export MAVEN_HOME

export PATH=${PATH}:${MAVEN_HOME}/bin

／／按esc键，输入“:qw!”，保存并退出编辑

4.测试

／／查看java和maven配置路径

appledeMacBook-Air:~ apple$ echo $JAVA_HOME

/Library/Java/JavaVirtualMachines/jdk1.8.0_77.jdk/Contents/Home/

appledeMacBook-Air:~ apple$ echo $MAVEN_HOME

／／键入java，javac，maven －version，查看是否配置成功

appledeMacBook-Air:~ apple$ mvn -version
