### 提示说，连接超时…那可不超时…没个梯子啥的能翻过那厚厚的墙才怪……  ###

**话不多说，直接说解决办法，不用翻墙之类，一个配置搞定全部 **

**配置文件已上传也可以直接下载————> [init.gradle 传送门(点击下载完全免费)][init.gradle]**

在用户/.gradle下（一般目录在：C:\\Users\\\[电脑的用户名称\]\\.gradle），新建一个  **init.gradle  **文件【注意后缀是 **.gradle**】 重启项目就可以了

allprojects {
        repositories {
            maven {
                url 'https://maven.aliyun.com/repository/public/'
            }
            maven {
                url 'https://maven.aliyun.com/repository/google/'
            }
    
            all { ArtifactRepository repo ->
                if (repo instanceof MavenArtifactRepository) {
                    def url = repo.url.toString()
    
                    if (url.startsWith('https://repo.maven.apache.org/maven2/') || url.startsWith('https://repo.maven.org/maven2') 
                        || url.startsWith('https://repo1.maven.org/maven2') || url.startsWith('https://jcenter.bintray.com/')

                        remove repo
                    }
                }
            }
        }

                            remove repo
                        }
