在 Android 中查找 google services 类路径时出错

Question

在将classpath 'com.google.gms:google-services:3.3.1'添加到build.gradle时，我收到此错误。有什么解决方案吗？

几件事。

项目级别生成。格拉德尔

dependencies {
classpath 'com.android.tools.build:gradle:3.1.2'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.2.31"
classpath 'com.google.gms:google-services:3.2.1' 
}

我建议将您的版本降低到 3.2.1，因为 3.3.1 中存在已知问题，会影响围绕模块、风格等进行编译。

其次，请证明您在模块build.gradle中也正确应用了该插件。

示例如下：

模块级构建。格拉德尔

dependencies {
implementation 'com.google.firebase:firebase-crash:15.0.2'
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
kapt "com.android.databinding:compiler:3.1.2"
//to compile @synchronized things and java references
implementation "org.jetbrains.kotlin:kotlin-stdlib-jre8:1.2.31"
implementation 'com.android.support:design:27.1.1'
implementation 'com.android.support:support-v4:27.1.1'
implementation 'com.android.support:cardview-v7:27.1.1'
implementation 'com.android.support:recyclerview-v7:27.1.1'
implementation 'com.github.barteksc:android-pdf-viewer:2.7.0'
implementation 'com.wajahatkarim3.EasyFlipView:EasyFlipView:2.0.5'
// [START firebase]
implementation 'com.google.firebase:firebase-core:15.0.2'
implementation 'com.google.firebase:firebase-messaging:15.0.2'
implementation 'com.google.firebase:firebase-appindexing:15.0.1'
implementation 'com.google.android.gms:play-services-base:15.0.1'
// [END   firebase]
implementation('com.crashlytics.sdk.android:crashlytics:2.7.1@aar') {
transitive = true
}  
apply plugin: 'com.google.gms.google-services'
}

当然，您只关心谷歌GMS部分，因此请确保您拥有该插件和依赖项。
