Android开发环境配置问题
全局build.gradle配置：

buildscript {
    repositories {
    	//建议直接使用maven镜像
        mavenCentral()
        maven{
            url 'http://maven.aliyun.com/nexus/content/groups/public/'
        }
    }
    dependencies {
    	//此版本是idea或者AndroidStudio中gradle插件框架版本
    	//与编译时gradle不是同一个
        classpath 'com.android.tools.build:gradle:2.2.2'
	}
	
}


allprojects {
    repositories {
    	//建议直接使用maven镜像
        mavenCentral()
        maven{
            url 'http://maven.aliyun.com/nexus/content/groups/public/'
        }
    }
}
task clean(type: Delete) {
    delete rootProject.buildDir
}

工程根目录下gradel/gradle-wrapper.properties配置：

#Mon Dec 28 10:00:20 PST 2015
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
#可以先下载好gradle
#然后通过file:///路径 引用本地包
distributionUrl=file:///D:/android/gradle/gradle-2.14.1-all.zip

app下build.gradle配置：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 29//导入sdk的版本
    buildToolsVersion "29.0.3"
    defaultConfig {
        applicationId "com.example.administrator.a9"
        minSdkVersion 21
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    //引入第三方jar包时会报错
    //加上lintOptions后就可以了
    lintOptions{
        abortOnError false
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    //com.android.support:appcompat-v7:+
    //这样联网更新解决版本不兼容会快点
    compile 'com.android.support:appcompat-v7:+'
    testCompile 'junit:junit:4.12'
}
