Maven安装和配置

Maven安装

官网下载：http://maven.apache.org/download.cgi

Maven 3.3 的JDK最低要求JDK7

cd /usr/local
下载压缩包：
wget http://mirrors.cnnic.cn/apache/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz
解压：
tar zxvf apache-maven-3.3.9-bin.tar.gz
修改目录名，默认的太长了：
mv apache-maven-3.3.9/ maven/

vim /etc/profile
# Maven
MAVEN_HOME=/usr/local/maven
PATH=$PATH:$MAVEN_HOME/bin
MAVEN_OPTS="-Xms256m -Xmx356m"
export MAVEN_HOME
export PATH
export MAVEN_OPTS

刷新配置文件：source /etc/profile

测试是否安装成功：mvn -version

Error: JAVA_HOME is not defined correctly.
  We cannot execute /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.171-8.b10.el7_5.x86_64/bin/java
报错的话，重新编译下vi /etc/profile

cat /etc/profile | tail -10
