android项目在…'应用程序“一个已解决的Google Play服务库依赖依赖于另一个精确版本

Question

我有一个应用程序运行良好，但今天它在构建项目时出现了错误。我花了一整天的时间，尝试了太多来自stack的解决方案。什么都没用。

我有以下应用程序-

apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

android {
    compileSdkVersion 29
    defaultConfig {
        applicationId "com.myapp.immuno"
        minSdkVersion 16
        targetSdkVersion 29
        versionCode 1
        versionName "2.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            aaptOptions.cruncherEnabled = false // here
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'com.google.android.material:material:1.0.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'

    implementation 'com.google.code.gson:gson:2.8.5'

    // Firebase libraries
    implementation 'com.google.firebase:firebase-core:17.2.1'

    implementation 'de.hdodenhof:circleimageview:2.2.0'

    // RecyclerView
    //noinspection GradleCompatible
    implementation 'com.android.support:recyclerview-v7:28.0.0'
    //FacebookSdk

    // volley library
    implementation 'com.android.volley:volley:1.1.1'

    implementation 'com.google.android.gms:play-services:17.0.0'
    implementation 'me.dm7.barcodescanner:zxing:1.9.8'

    annotationProcessor 'com.github.bumptech.glide:compiler:4.8.0'

    // To get date and time
    implementation 'net.danlew:android.joda:2.10.1.1'

    // external libraries for mail
    implementation files('libs/activation.jar')
    implementation files('libs/additionnal.jar')
    implementation files('libs/mail.jar')

    // Add the Fabric Crashlytics plugin.
    //classpath 'io.fabric.tools:gradle:1.31.2'
    // Add the Firebase Crashlytics dependency.
    implementation 'com.crashlytics.sdk.android:crashlytics:2.10.1'


    }

    apply plugin: 'com.google.gms.google-services'
`

build.gradle是

buildscript {
    repositories {
        google()
        jcenter()
        maven { url 'https://maven.fabric.io/public' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.3'
        classpath 'com.google.gms:google-services:4.3.3'
        classpath 'io.fabric.tools:gradle:1.31.2'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()

    }
}

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

在建筑项目上，我遇到了这个错误

错误：在项目“app”中，已解析的Google Play services库依赖于另一个精确版本（例如“[20.0.2]”），但未解析为该版本。库显示的行为未知。

依赖项失败：com.google.firebase:firebase消息：20.1.0-

The following dependencies are project dependencies that are direct or have transitive dependencies that lead to the art
ifact with the issue.
-- Project 'app' depends onto com.google.firebase:firebase-iid@{strictly 19.0.0}
-- Project 'app' depends onto com.google.firebase:firebase-core@17.2.1
-- Project 'app' depends onto com.google.firebase:firebase-crash@16.2.1

对于扩展调试信息，请使用从命令行执行Gradle/gradlew--信息：app:assembleDebug以查看工件的依赖路径。此错误消息来自google services Gradle插件，报告问题位于https://github.com/google/play-services-plugins并通过在构建中添加“googleServices{disableVersionCheck=false}”来禁用。gradle文件。

Answer 1

对我来说，重新启动电脑的老把戏成功了，因为在重新启动Android Studio并清除缓存后，我也遇到了同样的问题。

Answer 2

尝试以下两个步骤可以解决许多此类问题-

1. 建造-

干杯...

Answer 3

以下是我做的步骤和解决的问题：

1. 我换了com.google.firebase:firebase消息：20.1.0至com.google.firebase:firebase消息：20.0.1
2. 同步渐变
3. 和回滚更改（将20.0.1更改为20.1.0）
4. 如果同步并运行应用程序，您将看到该问题得到解决

我知道这不是正确的方法，但解决了我的问题。任何正确的都应该被替换。
