2.环境搭建

1.安装JDK

JDK：  https://www.injdk.cn/
maven: https://maven.apache.org/
注意： 使用 *.zip 或 *.tar.gz文件

2. 配置环境变量

2.1 windows
win + r ->  sysdm.cpl -> 高级 -> 环境变量

JAVA_HOME  : D:/xxx/jdk1.8.x
CLASSPATH  : .;%JAVA_HOME%/lib/ 
PATH       : %JAVA_HOME%/bin   # 注：PATH后追加,win7前加英文“分号”
MAVEN_HOME : D:/xxx/apache-maven-3.x.x
PATH       : %MAVEN_HOME%/bin  # 注：PATH后追加,win7前加英文“分号”

2.2 linux
vim /etc/profile  ->  source /etc/profile
export JAVA_HOME=/usr/share/jdk1.8.x
export CLASSPATH=.:$JAVA_HOME/lib 
export MAVEN_HOME=/usr/share/maven-3.x.x
export PATH=$JAVA_HOME/bin:$MAVEN_HOME/bin:$PATH

2.3 Java环境测试
java -version
javac
javap
mvn -version

3. maven配置

新建repo目录： xxx/apache-maven-3.x.x/repo
修改默认设置: xxx/apache-maven-3.x.x/conf/settings.xml
