Linux maven 安装

安装maven：先安装jdk。

下载地址：

https://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/

安装：

tar -xf apache-maven-3.6.2-bin.tar.gz -C /usr/local/
ln -sv apache-maven-3.6.2/ maven

环境变量：

vim /etc/profile.d/maven.sh
export MAVEN_HOME=/usr/local/maven
export PATH=$PATH:${MAVEN_HOME}/bin

source /etc/profile.d/maven.sh

配置本地仓库和远程仓库：

vim /usr/local/maven/conf/settings.xml

设置本地仓库位置：在<localRepository>标签下加入

<localRepository>/usr/local/maven/repository</localRepository>

远程仓库位置：在<mirrors>标签下加入

<mirror>
    <id>alimaven</id>
    <name>aliyun maven</name>
    <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
    <mirrorOf>central</mirrorOf>
</mirror>

查看版本：

mvn -version

为jenkins调用maven创建软连接：jenkins默认从/usr/bin目录下调用maven

ln -sv /usr/local/apache-maven-3.6.2/bin/mvn /usr/bin/mvn

maven编译打包：

pom.xml是依赖管理，如下示例

清理之前的编译：

mvn clean

打包：

mvn package

运行项目：要安装tomcat

mvn tomcat:run
