我在项目级别的毕业生

buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.2'
classpath 'com.google.gms:google-services:3.3.1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}

您需要从浓缩咖啡核心中排除支持库，如下所示：

androidTestImplementation('com.android.support.test.espresso:espresso- 
core:3.0.2') {
exclude group: 'com.android.support', module: 'support-annotations'
}

您还需要确保您的appcompat库和design库具有相同的最新版本，如下所示：

implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:design:27.1.1'
