一、新建Gradle Project，点下一步输入项目名

1、在Gradle distribution选择Local installation directory，填写Gradle Home路径

E:\gradle-2.11

2、在Advanced options里填写Gradle user home directory，这只存放gradle下载的jar包的路径，默认在C盘的User文件夹下

E:\gradle

3、点下一步，在点击finish就完成项目创建

二、build.gradle文件

apply plugin: 'java'// In this section you declare where to find the dependencies of your projectrepositories {    // Use 'jcenter' for resolving your dependencies.    // You can declare any Maven/Ivy/file repository here.    jcenter() //gradle默认的中央仓库    mavenCentral() //自己添加的Maven中央仓库}// In this section you declare the dependencies for your production and test codedependencies {    // The production code uses the SLF4J logging API at compile time    compile 'org.slf4j:slf4j-api:1.7.14'    compile 'com.google.code.gson:gson:2.6.2' //添加自己要用的jar包依赖        // Declare the dependency for your favourite test framework you want to use in your tests.    // TestNG is also supported by the Gradle Test task. Just change the    // testCompile dependency to testCompile 'org.testng:testng:6.8.1' and add    // 'test.useTestNG()' to your build script.    testCompile 'junit:junit:4.12'}

右键项目，选择Gradle--》Refresh Gradle Project将自动下载依赖

至此，就可以使用gson包了
