Jenkins自动构建部署maven项目的WEB项目

参考文档：https://www.jianshu.com/p/60fb231a160e

• Jenkins安装过程略，参考Jenkins环境构建

• 配置系统工具

配置maven配置文件地址，就在maven的conf目录下的settings.xml文件

配置JDK位置

配置git位置，git是安装的，可以使用下述命令获取git位置

配置maven位置

• 安装插件

目标是将项目打包后发布到tomcat中去，所以现在我们需要安装一个发布到tomcat的jenkins插件点击系统管理，选择管理插件

点击可选插件，然后在右上方搜索框搜索container，选择Deploy to container Plugin，点击安装即可

• jenkins从Git自动下载项目，通过maven编译部署到Tomcat

1.新建项目

点击左上方新建，新建构建项目

填写项目名，选择自由风格

配置源码管理

构建配置

添加tomcat凭证

同时，也需要在E:\tomcat\apache-tomcat-8.0.35\conf\tomcat-users.xml添加权限

<role rolename="manager"/>　  
<role rolename="manager-gui"/>　  
<role rolename="admin"/>　  
<role rolename="admin-gui"/>　  
<role rolename="manager-script"/>  
<user username="tomcat" password="tomcat" roles="admin-gui,admin,manager-gui,manager,manager-script"/>

构建后步骤 选择发布war包到一个容器中

• 开始构建

点击左方的立即构建，下方会出现构建队列

点击进入队列，然后点击Console output 可以看到构建过程中打印的日志信息，可以用来在构建失败时排错

构建之后，会看到输出提示

看一看是否成功发布了

我的tomcat地址是http://localhost:8082/apidoc，之前填写contextpath是apidoc

注意：tomcat服务一定要是开着的，否则会报如下错误
