Could not download okhttp.jar (com.squareup.okhttp3:okhttp:3.10.0)

在gradle里面加上这句

allprojects {
    repositories {
        mavenCentral()
        google()
        jcenter()
        maven { url 'https://maven.google.com' }
        maven {
            url 'https://oss.sonatype.org/content/repositories/snapshots'
        }
        maven { url "https://jitpack.io" }
    }
}

 

然后再加上

repositories {
    google()
    mavenCentral()
}
