Android 在模块jetified-google-play-services.jar和jetified-play-services-base-17.0.0-runtime.jar中发现重复的类

在重新启动Android Studio后，我在Android Studio中从一秒到另一秒出现了这个错误。现在我不能再建立我的项目了。我使用离子4和电容器为我的android项目

这是ionic cordova插件中的my build.gradle文件：

buildscript {
    repositories {

    }
    dependencies {

这是我的android项目build.gradle：

//顶级生成文件，您可以在其中添加所有子项目/模块通用的配置选项

buildscript {

    repositories {
        google()
        jcenter()

        classpath 'com.google.gms:google-services:4.3.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

apply from: "variables.gradle"

allprojects {
    repositories {
        google()
        jcenter()
    }
}

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

因为我不知道发生了什么，我不知道要给你看什么，所以请问你是否需要更多，我会补充的。不知怎的，我找不到解决这个错误的办法。阅读Android平台没有帮助。

您可以通过将其添加到

build.gradle

中的

Android

块来解决此问题：

configurations {
    implementation.exclude module:'proto-google-common-protos'
    implementation.exclude module:'protolite-well-known-types'
    implementation.exclude module:'protobuf-lite'
}
