gradle一个错误处理

Could not find com.android.tools.build:gradle:2.2.3.
Could not resolve com.android.tools.build:gradle:2.2.3.

下面几个方法可能有用

1、删除.gradle目录重新下载，C:\Users\Lenovo\.gradle

2、清理编译目录，重新编译。

3、修改build.gradle,重新编译i，这个方法用用。

buildscript {

    repositories {

    maven { url 'https://maven.aliyun.com/repository/central' }

            maven { url 'https://maven.aliyun.com/repository/jcenter' }

            maven { url 'https://maven.aliyun.com/repository/google' }

            maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }

            maven { url 'https://maven.aliyun.com/repository/public' }

            maven { url 'https://jitpack.io' }

            maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }

            jcenter()

    }

    dependencies {

        classpath 'com.android.tools.build:gradle:2.2.3'

    }

}

allprojects {

    repositories {

    maven { url 'https://maven.aliyun.com/repository/central' }

            maven { url 'https://maven.aliyun.com/repository/jcenter' }

            maven { url 'https://maven.aliyun.com/repository/google' }

            maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }

            maven { url 'https://maven.aliyun.com/repository/public' }

            maven { url 'https://jitpack.io' }

            maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
