Mac配置Java开发环境_mac java开发环境配置

一、配置JDK

1、下载JDK

一般使用jdk 8，下载地址：Java Downloads | Oracle，官网上只显示1.8.0_351版本，我就下载了它

2、安装jdk

下载后直接安装，都点下一步就好，这里就不截图了。

3、检查jdk安装是否成功

Mac-mini ~ % java -version
java version "1.8.0_351"
Java(TM) SE Runtime Environment (build 1.8.0_351-b10)
Java HotSpot(TM) 64-Bit Server VM (build 25.351-b10, mixed mode)

4、找到jdk安装路径

Mac-mini ~ % /usr/libexec/java_home
/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

5、配置环境变量

编辑.profile文件，输入以下内容

vi ~/.profile
 
JAVA_HOME="/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home"
CLASS_PATH="$JAVA_HOME/lib"
PATH=".$PATH:$JAVA_HOME/bin"
export JAVA_HOME
export PATH
export CLASS_PATH
 
 
保存后再重加载该文件
source ~/.profile 

6、查看是否生效

Mac-mini ~ % echo $JAVA_HOME       
/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

二、安装Maven环境

1、下载maven

Maven – Download Apache Maven下载最新版本

2、解压到自己指定目录

ac-mini apache-maven-3.8.6 % pwd
/Users/songyun/tool/apache-maven-3.8.6

 3、配置环境变量

vi .bash_profile
 
export M="/Users/songyun/tool/apache-maven-3.8.6"
export PATH="$M/bin:$PATH"
 
source .bash_profile

4、查看是否配置成功

Mac-mini ~ % mvn -v
