解決方法:
安裝maven 並配置到jenkins配置裏 下載地址 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 -> 系統管理 -> 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安裝，Name（自定義，如maven3.5.2），MAVEN_HOME填 “/usr/local/apache-maven-3.5.2” 左下角“save”
安裝maven 也可以參考：http://www.cnblogs.com/weifeng1463/p/8920765.html
安裝jdk jenkins -> 系統管理 -> 全局工具配置 JDK安裝 JDK 別名 JDK1.8 自動安裝 從java.sun.com 安裝 版本 Java SE Development Kit 8u162
最後測試可以成功構建：
