本文介绍了在jenkins中maven的安装及配置（安装maven及jdk的方法），以及如何在jenkins中创建maven任务。

有三点需要注意的地方。

maven一定要安装在jenkins服务器上。
maven安装之前要先安装jdk。
建任务前，需要有git环境，并配置好用户名密码。

1. JDK的安装

centos7是自带OPEN JDK1.8的，但是不建议用，因为后面在jenkins中配置JDK目录的时候，自带的OPEN JDK无法识别，还是建议到官网下载安装。

1）到oracle官网下载JDK1.8文件，并上传至服务器解压缩，无需安装，直接使用。

2）执行java文件，看下版本。

2. maven的安装

1）到apache官网下载maven 包，并上传至服务器，无需安装，解压直接使用。

2）配置maven文件settings.xml，在/app/maven-3.0.5/conf下。

主要修改2个地方，localRepository目录以及 MIRRORS镜像的URL（国外的太慢，改为阿里云的）。

localRepository目录修改方式：

默认在m2下，我们自己新建一个目录/app/maven-3.0.5/mvnrepository，重新添加一行


  /app/maven-3.0.5/mvnrepository

依赖包镜像的下载地址URL修改方式：


  
    
  
      alimaven
      aliyun maven
      http://maven.aliyun.com/nexus/content/groups/public/
      central

3. 服务器系统环境变量的设置

1）编辑环境变量文件 vi /etc/profile

2）添加如下变量（根据自己的安装目录设置）

export JAVA_HOME=/app/jdk1.8.0_201
export MAVEN_HOME=/app/maven-3.0.5
export PATH=$JAVA_HOME/bin:$PATH:$MAVEN_HOME/bin

3）生效环境变量，source /etc/profile

4）验证环境变量是否生效。能正确显示版本、home路径即可。

4.jenkins中的变量设置

1）设置全局工具配置

新增JDK设置，目录为上面讲的安装目录。（不能用系统自带的OPENJDK，不然会提示报错）

新增MVN设置

2）设置系统配置，增加环境变量，共3个，根据自己的安装目录填写。

5. 在jenkins中新建maven项目

1) 构建一个maven项目

2）源码部分，根据自己的情况填写。

3）PRE STEP部分，"ROOT POM"还是使用pom.xml文件，"Goals and options"根据maven的命令填写，具体可以看提示Specifies the goals to execute, such as "clean install" or "deploy". This field can also accept any other command line options to Maven, such as "-e" or "-Djava.net.preferIPv4Stack=true".

4）Post Steps我们先不填，先运行下看看是否可以编译成功。

5）运行任务，第一次运行会下载大量的java依赖包。

最后会出现success，说明编译成功。

在会在maven设localRepository目录下，生成war包。
