未解析的 RxJava 依赖项无法下载 RxJava.jar

Question

我从未使用过这个库。它无法正确同步，但我的互联网运行良好，可以下载该.jar文件

这是我的错误：

这是我 build.app 毕业生：

apply plugin: 'com.android.application'
android {
compileSdkVersion 27
defaultConfig {
applicationId "com.tekemuradov.aman.ulgmada"
minSdkVersion 18
targetSdkVersion 26

vectorDrawables.useSupportLibrary = true
}

}

apply plugin: 'com.google.gms.google-services'
configurations.all{
resolutionStrategy.eachDependency{DependencyResolveDetails details ->
def requested = details.requested
if(requested.group == 'com.android.support'){
if (!requested.name.startsWith("multidex")){
details.useVersion('27.0.2')
}
}
}
}

这是我的 build.project gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.4'


// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
classpath 'com.google.gms:google-services:4.1.0'
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
