自动化发布-7.Gradle脚本编写

原文日期：2017-01-27

在前面我们使用Jenkins插件执行远程shell，其实我们可以通过不需要ssh插件，所有事情可以放在Gradle脚本中执行。这里我举个典型的案例。

通过Jenkins Gitlab插件可以实现获取代码仓库的项目源代码，并且编译项目源代码。可以在Gradle中引入ssh插件，让Gradle去执行应用重启发布。如下脚本。

buildscript {
  repositories {
    maven {
      url "http://192.168.1.88/nexus/content/groups/public/"
    }
  }
  dependencies {
    classpath 'com.oracle:ojdbc6:11.2.0.3'
    classpath 'mysql:mysql-connector-java:5.1.40'
    classpath "org.flywaydb:flyway-gradle-plugin:4.0.3"
    classpath 'org.hidetake:gradle-ssh-plugin:2.7.0'
  }
}

apply plugin: "org.flywaydb.flyway"
apply plugin: "org.hidetake.ssh"

ext {
	projectName="test"
	tomcatHome = "/app/tomcat/apache-tomcat.8.0.59"
	appHome = "/app/application"
	env = System.getProperty("env")
}
//项目打包
task process (type:Exec) {
	workingDir '.'
	commandLine 'tar','-zcf','test.tar.gz','test'
}

//加载properties属性文件
def loadProperties(){
	def configPath = "../deploy-project-config/sale-support/config/${env}/config.properties"
    def props = new Properties()
	def configFile = file(configPath)
    configFile.withInputStream{stream -> props.load(stream)}
    props
}
//设置flyway插件连接属性
flyway {
	Properties props = loadProperties()
    user = props.'conn1.jdbc.username'
    password = props.'conn1.jdbc.password'
    url = 'jdbc:oracle:thin:@(DESCRIPTION= (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))(LOAD_BALANCE = no)(CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = xszcsrv)(FAILOVER_MODE =(TYPE = SELECT)(METHOD = BASIC)(RETRIES = 180)(DELAY = 5))))'
	locations = ['filesystem:sql']
}

//设置远程服务器地址信息
remotes {
  webServer31 {
    host = '192.168.1.31'
    user = 'test'
    password = 'password'
	//identity = file('/root/.ssh/id_rsa') 
  }
  webServer32 {
    host = '192.168.1.32'
    user = 'test'
    password = 'password'
	//identity = file('/root/.ssh/id_rsa') 
  }
  webServer33 {
    host = '192.168.1.33'
    user = 'test'
    password = 'password'
	//identity = file('/root/.ssh/id_rsa') 
  }
}
//ssh插件设置,并定义方法
ssh.settings {  
  knownHosts = allowAnyHosts
