无法解决 com.google.android.gms:play-services-measurement-base:[18.0.0]。

Question

我对Flutter相对陌生，该项目两天前还能正常运行。今天尝试运行时，遇到了这个错误。以下是错误信息：

FAILURE: Build failed with an exception.

这是我应用程序的 "app\build.gradle" 的代码。

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'com.google.gms.google-services'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

android {
    compileSdkVersion 29

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    lintOptions {
        disable 'InvalidPackage'
    }

    defaultConfig {
        applicationId "com.project.project"
        minSdkVersion 21
        targetSdkVersion 29
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        multiDexEnabled true
    }

    buildTypes {
        release {
            signingConfig signingConfigs.debug
        }
    }
}

flutter {
    source '../..'
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation platform('com.google.firebase:firebase-bom:26.1.1')
    implementation 'com.google.firebase:firebase-analytics'
    implementation 'com.android.support:multidex:1.0.3'
}

我尝试更新firebase-bom和google-services，但仍然遇到同样的问题。 非常感谢您的任何帮助！

你在 android/build.gradle 中加入了 classpath 'com.google.gms:google-services:4.3.8' 吗？ - Ananda Pramono

我试过了。我使用的是 classpath 'com.google.gms:google-services:4.3.4'，但即使更新后也没有起作用。 - DoggyStick

有什么解决办法吗？ - Dhanraj Verma

@DhanrajVerma 你可以尝试MrZero的答案，这对我很有效。如果对你仍然无效，那么一个临时的解决方法是在构建应用程序时关闭WiFi。之后可以再打开它。 - DoggyStick

Answer 1

在gradle-wrapper.properties文件中，将distributionUrl改为

distributionUrl=https://services.gradle.org/distributions/gradle-6.5.1-all.zip

对于未来的读者，请查看此处以获取更多关于此内容的信息以及如何获取当前版本。 - Tom Doodler

我也遇到了同样的问题。我正在使用以下依赖项 { classpath 'com.android.tools.build:gradle:3.5.0' classpath 'com.google.gms:google-services:4.3.5' } - Janaka

我有类似的问题。我正在使用以下依赖项 { classpath 'com.android.tools.build:gradle:3.5.0' classpath 'com.google.gms:google-services:4.3.5' } 我应该使用什么 distributionUrl？ - Janaka

Answer 2

请删除此行，这是Firebase插件添加的。

implementation platform('com.google.firebase:firebase-bom:26.1.1')

implementation 'com.google.firebase:firebase-analytics'

将gradle版本设置为4.1.0

并将发行版url设置为distributionUrl=https://services.gradle.org/distributions/gradle-6.5-all.zip

谢谢，它像魔法一样工作。你让我的一天！！ - Loc Le Xuan

对我来说有效，但需要额外的步骤将 compileSdkVersion 28 更改为 compileSdkVersion 31。 - DaReal
