Jenkins 常用的项目构建工具集成 02 Gradle

gradle相对于maven项目来说，打包速度会快一些（这个工具也需要Java的环境）和之前maven创建项目一样，这个不变。

下载gradle构建工具

创建gradle项目 

将项目推送到gitlab上面

[root@jenkins-master ~]# cd devops-gradle-service-master
[root@jenkins-master devops-gradle-service-master]# ls
build.gradle  gradle  gradlew  gradlew.bat  Jenkinsfile  settings.gradle  src

安装配置

unzip gradle-6.8.3-bin.zip -d /usr/local/
export GRADLE_HOME=/usr/local/gradle-6.8.3/
export PATH=$GRADLE_HOME/bin:$PATH
gradle -v

gradle项目的构建

常用命令

• gradle build  构建项目
• gradle build -x test 构建项目跳过测试
• gradle clean 清空构建目录

我们这里使用远程的Jenkinsfile，也就是将Jenkinsfile存放在远程的版本系统里面，添加一个Jenkinsfile 

配置仓库地址

  配置SCM这里会多出代码下载的步骤  

现在要跳过这个阶段，下面生成代码

options {
  skipDefaultCheckout true
}

 gradle在build的时候会去做测试，gradle buid会去做测试，如果gradle build -x test就会跳过测试

[root@jenkins-master devops-gradle-service-master]# gradle build
Starting a Gradle Daemon (subsequent builds will be faster)
