安装maven 并配置到jenkins配置里 下载地址 https://maven.apache.org/download.cgi wget http://mirror.bit.edu.cn/apache/maven/maven-3/3.5.2/binaries/apache-maven-3.5.2-bin.tar.gz tar zxvf apache-maven-3.5.2-bin.tar.gz mv apache-maven-3.5.2 /usr/local/ /usr/loca/apache-maven-3.5.2/bin/mvn --version jenkins -> 系统管理 -> 全局工具配置 Maven Configuration -> Settings file in filesystem -> File Path /usr/local/apache-maven-3.5.2/conf/settings.xml Global settings file on filesystem -> File Path 同上 下拉到Maven，Maven安装，Name（自定义，如maven3.5.2），MAVEN_HOME填 “/usr/local/apache-maven-3.5.2” 左下角“save”
安装maven 也可以参考：http://www.cnblogs.com/weifeng1463/p/8920765.html
安装jdk
jenkins -> 系统管理 -> 全局工具配置
JDK安装
JDK 别名 JDK1.8
自动安装
从java.sun.com 安装
版本 Java SE Development Kit 8u162
最后测试可以成功构建：
