Gradle学习教程之部署上传项目详解

前言

Gradle,这是一个基于 JVM 的富有突破性构建工具。Gradle 正迅速成为许多开源项目和前沿企业构建系统的选择,同时也在挑战遗留的自动化构建项目。

原先在公司做项目时，写了一个简单的基于gradle部署项目的脚本，今天翻出来记录一下，下面话不多说了，来一起看看详细的介绍吧。

方法如下：　

一、build.gradle

buildscript {
 ext {
 env = System.getProperty("env") ?: "test"
 jvmArgs = "-server -Xms128m -Xmx128m -XX:NewRatio=4 -XX:SurvivorRatio=16 -XX:MaxTenuringThreshold=15 -XX:CMSInitiatingOccupancyFraction=80 -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled -XX:+ExplicitGCInvokesConcurrent -XX:+DoEscapeAnalysis -XX:-HeapDumpOnOutOfMemoryError"
 if (env == "prod") {
 jvmArgs = "-server -Xms2g -Xmx2g -XX:NewRatio=4 -XX:SurvivorRatio=16 -XX:MaxTenuringThreshold=15 -XX:CMSInitiatingOccupancyFraction=80 -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled -XX:+ExplicitGCInvokesConcurrent -XX:+DoEscapeAnalysis -XX:-HeapDumpOnOutOfMemoryError"
 }
 userHome = System.getProperty("user.home")
 osName = System.getProperty("os.name")
 }

 repositories {
 jcenter()
 }
 dependencies {
 classpath 'org.hidetake:gradle-ssh-plugin:2.7.0'
 classpath 'co.tomlee.gradle.plugins:gradle-thrift-plugin:0.0.6'
 }
}

allprojects {
 apply plugin: 'idea'
 apply plugin: 'eclipse'
 apply plugin: 'org.hidetake.ssh'
 group = 'com.mwee.information.core'
 version = '1.0-SNAPSHOT'
 ssh.settings {
 timeoutSec = 60
 knownHosts = allowAnyHosts
 }
 defaultTasks 'clean', 'copyPartDependencies'

 //排除Log4j依赖
 configurations {
 compile.exclude module: 'slf4j-log4j12'
 compile.exclude module: 'org.apache.logging.log4j'
 compile.exclude module: 'log4j'
 all*.exclude group: 'org.apache.logging.log4j'
 all*.exclude group: 'log4j'
 }

}

subprojects {
 apply plugin: 'java'
 sourceCompatibility = 1.8
 targetCompatibility = 1.8
 repositories {
 mavenLocal()
 maven { url "http://114.80.88.52:9001/nexus/content/groups/public/" }
 }
 sourceSets {
 main {
 java {
 srcDirs = ['src/main/java']
 }
 resources {
 srcDirs = ["src/main/resources", "src/main/profile/$env"]
 }
 }
 }

 compile("org.apache.commons:commons-collections4:4.1")
 compile "org.apache.commons:commons-pool2:2.4.2"

 }
 //gradle utf-8 compile
 tasks.withType(JavaCompile) {
 options.encoding = 'UTF-8'
 }

 task copyAllDependencies(type: Copy, dependsOn: jar) {
 description = "拷贝全部依赖的jar包"
 from configurations.runtime
 into 'build/libs'
 }

 task copyPartDependencies(type: Copy, dependsOn: jar) {
 description = "拷贝部分依赖的jar"
 from configurations.runtime
 into 'build/libs'
 doLast {
 file("build/libs").listFiles({ !it.name.endsWith("-SNAPSHOT.jar") } as FileFilter).each {
 it.delete()
 }
 }
 }
}

二、对应模块下的build.gradle

def mainClass = "com.hzgj.information.rest.user.run.UserServiceProvider"
def appHome = "/home/appsvr/apps/rest_user"
def javaCommand = "nohup java $jvmArgs -Djava.ext.dirs=$appHome/libs -Denv=$env $mainClass >$appHome/shell.log 2>&1 &"
def index = System.getProperty("index")

def remote = remotes {
 test_0 {
 role 'test_0'
 host = '10.0.21.152'
 if (file("$userHome/.ssh/id_rsa").exists()) {
 user = 'appsvr'
 identity = file("$userHome/.ssh/id_rsa")
 } else {
 user = 'appsvr'
 password = 'xxx'
 }

 }

 test_1 {
 role 'test_1'
 host = '10.0.146.20'
 if (file("$userHome/.ssh/id_rsa").exists()) {
 user = 'appsvr'
 identity = file("$userHome/.ssh/id_rsa")
 } else {
 user = 'appsvr'
 password = 'xxx'
 }
 }
 home {
 role 'home'
 host = '192.168.109.130'
 user = 'appsvr'
 password = 'xxx'
 // identity = file('id_rsa')
 }

}
task deploy << {
 description = "拷贝jar包并启动java服务"
 def roles = remote.findAll {
 def currentEnv = index == null ? "$env" : "$env" + "_" + index
 it['roles'][0].toString().contains(currentEnv)
 }
 ssh.run {
 roles.each {
 def role = it['roles'][0].toString()
 session(remotes.role(role)) {
 try {
 execute("ls $appHome")
 } catch (Exception e) {
 println("#############目录[$appHome]不存在,将自动创建############")
 execute("mkdir -p $appHome")
 }
 finally {
 def r = '$1'
 def pid = execute("jps -l |grep '$mainClass' |awk \'{print $r}\'")
 if (pid) {
 execute("kill -9 $pid")
 }
 put from: 'build/libs', into: "$appHome"
 println("###############准备启动java服务[$javaCommand]####################")
 execute("$javaCommand")
 sleep(10000)
 pid = execute("jps -l |grep '$mainClass' |awk \'{print $r}\'")
 if (pid) {
 println("#####$mainClass [$pid] 启动成功...######")
 execute("rm -f $appHome/shell.log")
 } else {
 println("#$mainClass 启动失败...输出日志如下:#")
 execute("cat $appHome/shell.log")
 }
 }
 }
 }

 }
}

task stop << {
 def roles = remote.findAll {
 def currentEnv = index == null ? "$env" : "$env" + "_" + index
 it['roles'][0].toString().contains(currentEnv)
 }
 ssh.run {
 roles.each {
 session(remotes.role("$env")) {
 def r = '$1'
 def pid = execute("jps -l |grep '$mainClass' |awk \'{print $r}\'")
 if (pid) {
 execute("kill -9 $pid")
 }
 }
 }
 }
}
task start << {
 def roles = remote.findAll {
 def currentEnv = index == null ? "$env" : "$env" + "_" + index
 it['roles'][0].toString().contains(currentEnv)
 }
 ssh.run {
 roles.each {
 def role = it['roles'][0].toString()
 session(remotes.role(role)) {
 def r = '$1'
 def pid = execute("jps -l |grep '$mainClass' |awk \'{print $r}\'")
 if (pid) {
 execute("kill -9 $pid")
 }
 println("###############准备启动java服务[$javaCommand]####################")
 execute("$javaCommand")
 sleep(10000)
 pid = execute("jps -l |grep '$main Class' |awk \'{print $r}\'")
 if (pid) {
 println("#$mainClass [$pid] 启动成功...#")
 execute("rm -f $appHome/shell.log")
 } else {
 println("#$mainClass 启动失败...输出日志如下:#")
 execute("cat $appHome/shell.log")
 }
 }
 }
 }
}

三、使用方式

1.先运行gradle copyAll -x test 进行打包操作，该操作会将该模块所有的依赖的jar

2.进入到对应的模块下 运行gradle deploy -Denv=xxx -Dindex=xxx ,什么意思呢？-Denv代表哪一个环境 -Dindex指定该环境下哪个节点进行发布

3.gradle start -Denv=xxx -Dindex=xxx 运行当前环境下的应用
