第一个gradle工程

1. 下载gradle，并配置

2. 配置idea的gradle（不支持，可以下插件）

3. 创建gradle项目

4 配置依赖

plugins {
    id 'java'
}

group 'com.xf'
version '1.0'

//jdk encode
sourceCompatibility = 1.8
targetCompatibility = 1.8
compileJava.options.encoding = 'UTF-8'
compileJava.options.encoding = 'UTF-8'

//仓库配置
repositories {
    mavenLocal()        //使用本地仓库
    maven { name "Alibaba"; url "https://maven.aliyun.com/repository/public" }
    mavenCentral()      //使用maven中心仓库
}

//版本控制
project.ext {
    hadoopVersion = '2.6.5'
    sparkVersion = '2.4.0'
    scalaVersion = '2.11.8'
    slf4jVersion = '1.7.7'
    log4jVersion = '1.2.17'
    hbaseVersion = '2.2.0'
    esVersion = '7.3.1'
    junitVersion = '4.12'
}
//
dependencies {
    compile group: 'org.apache.spark', name: 'spark-core_2.11', version: sparkVersion
    compile(
            'org.apache.hadoop:hadoop-client:' + hadoopVersion,
            'org.apache.spark:spark-sql_2.11:' + sparkVersion,
            'org.scala-lang:scala-library:' + scalaVersion,
            'org.elasticsearch.client:elasticsearch-rest-high-level-client:' + esVersion,
            'org.apache.hbase:hbase-client:' + hbaseVersion
    )
    runtime(
            'org.slf4j:slf4j-log4j12:' + slf4jVersion,
            'log4j:log4j:' + log4jVersion
    )
    testCompile group: 'junit', name: 'junit', version: junitVersion
}

5 并测试运行
