解决Kotlin部分依赖无法下载的问题

依赖如下:

buildscript {
    ext.kotlin_version = '1.3.2'
    repositories {
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
        maven { url 'http://maven.aliyun.com/nexus/content/repositories/jcenter' }
        maven {url "https://maven.google.com"}
        google()
        jcenter()
        maven { url "https://jitpack.io" }
        mavenCentral()
        jcenter { url "http://jcenter.bintray.com/" }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.0.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

    }

allprojects {
    repositories {
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
        maven { url 'http://maven.aliyun.com/nexus/content/repositories/jcenter' }
        maven {url "https://maven.google.com"}
        google()
        jcenter()
        maven { url "https://jitpack.io" }
        mavenCentral()
        jcenter { url "http://jcenter.bintray.com/" }
    }
}
