在Android Studio 3.1.2中添加Volley的问题

Question

我想在Android Studio 3.1.2中为我的项目添加Volley。我正在尝试使用implementation 'com.android.volley:volley:1.1.0'。

这是项目的Gradle：

buildscript {
    ext.kotlin_version = '1.2.41'
    repositories {
         google()
         jcenter()
    }
    dependencies {
         classpath 'com.android.tools.build:gradle:3.1.2'
         classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven { url "https://jitpack.io" }
        mavenCentral()
        maven {
            url "https://maven.google.com"
            name 'Google'
        }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

但它失败并出现以下错误：

Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve com.android.volley:volley:1.1.0.

这是错误的形象，希望能更好地理解问题。

我在这里缺少什么？

Answer 1

事实证明，Invalidate Caches / Restart做了伎俩！

Answer 2

将其替换为implementation 'com.android.volley:volley:1.1.1'

这肯定会解决问题。
