Gradle进阶：5:结合Jenkins进行持续集成

结合Jenkins进行gradle的持续构建有多种方式，可以在Jenkins的容器种直接安装gradle并直接使用，也可以通过jenkins的gradle插件进行使用，也可以通过调用gradle的镜像来进行使用。这篇文章以jenkins的gradle插件使用方式为例，介绍如何在jenkins中使用gradle。

Jenkins的gradle插件

插件安装方式

可以通过命令行install-plugins.sh gradle方式进行插件安装，也可以通过Jenkins的界面直接安装gradle

安装gradle

gradle插件只是负责调用gradle，当然也可以通过gradle插件安装，无论哪种方式，在jenkins中能够调用到gradle这件事情是整个集成的前提和条件。因为这里示例的jenkins是运行在容器中的，所以在jenkins的镜像中需要确保能够执行gradle的命令（如果不是镜像方式，只需要保证安装在同一台机器上，并且具有权限即可）

~ # /usr/local/share/gradle/bin/gradle --version

设定gradle

在Jenkins的Global Tool Configuration中设定如下Gradle的信息

使用jenkins执行构建

gradle的spring boot的demo应用

将gradle的demo应用上传到自行搭建的gitlab，包括gitlab和svn相关的版本管理等请参看：https://blog.csdn.net/liumiaocn/article/details/82286778

创建一个free style的jenkins的job

创建一个free style的jenkins的job，注意如下两项设定：

• 设定gitlab的代码仓库信息
  

• 设定gradle信息
  注意此处选定上文中已经设定的名为gradle的工具信息，而此gradle的HOME目录则位于jenkins的/usr/local/share/gradle/下。
  

执行构建

这样即可执行构建，执行构建的日志信息如下所示：

• 确认结果
  进到jenkins的构建目录中可以确认，build相关的目录下的内容均已完成，包括spring boot的jar文件以及jacoco的单体测试覆盖率报告的信息等。
