找不到design.jar (com.android.support:design:27.0.0)

Question

每次我试图构建apk时，都会出现以下错误：

> Could not find multidex.jar (com.android.support:multidex:1.0.2).
  Searched in the following locations:
      https://jcenter.bintray.com/com/android/support/multidex/1.0.2/multidex-1.0.2.jar
> Could not find design.jar (com.android.support:design:27.0.0).
  Searched in the following locations:
      https://jcenter.bintray.com/com/android/support/design/27.0.0/design-27.0.0.jar
> Could not find common.jar (android.arch.core:common:1.0.0).
  Searched in the following locations:
      https://jcenter.bintray.com/android/arch/core/common/1.0.0/common-1.0.0.jar

我检查了JCenter状态，它正常工作。

那为什么失败了？

UPD

几天前构建的代码是相同的！

以下是项目级别的build.gradle

buildscript {
    repositories {
        jcenter()
        mavenCentral()
        google()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.0'
        classpath 'com.google.gms:google-services:3.2.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        maven {
            // All of React Native (JS, Android binaries) is installed from npm
            url "$rootDir/reactnative/node_modules/react-native/android"
        }
        jcenter()
        maven { url "https://jitpack.io" }
        maven {url "https://clojars.org/repo/"}
        maven { url "https://maven.google.com" }
        mavenCentral()
    }
}

Answer 1

com.android.support:design:27.0.0不在jcenter()存储库中，而是在google()存储库中。看看您的错误日志，似乎Android正在试图在jcenter()中找到它。要强制它在google()内部查看，请将google()作为您的第一条语句，或者将其放在jcenter()之上的两个repositories{..}块中。

repositories {
    ...
    google()
    jcenter()
    ...
}
