找不到support-media-compat.aar

Question

尝试将Firebase连接到android gradle应用。一旦添加了Firebase依赖项，我将收到以下构建错误。

FAILURE: Build failed with an exception.

看起来它只是在搜索jcenter。但是jcenter的每个引用都列出了要搜索的其他存储库。

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:3.2.0"

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

        classpath 'com.google.gms:google-services:4.2.0' // google-services plugin
    }
}

allprojects {
    repositories {
        jcenter()
        google()
        maven {
            url 'https://maven.google.com'
        }
    }
}

app / build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    buildToolsVersion "28.0.3"
    defaultConfig {
        applicationId "io.nme.samples.displayingabitmap"
        minSdkVersion 16
        targetSdkVersion 28
        versionCode 181
        versionName "1.0.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    api fileTree(dir: 'libs', include: ['*.jar'])
    androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    api 'com.android.support:appcompat-v7:24.2.1'
    api 'com.android.support:support-v4:24.2.1'

    testImplementation 'junit:junit:4.12'

    dependencies {

        api project(':extension-api')
        api project(':haxe-firebase')
    }

    implementation 'com.google.firebase:firebase-core:16.0.4'
}

// ADD THIS AT THE BOTTOM
apply plugin: 'com.google.gms.google-services'

我在这里想念什么？

Answer 1

我遇到了有关查找库的同一问题。但是，通过调整存储库顺序，此问题已得到解决。

repositories {
    google()
    jcenter()
    // others
}

看起来，由Google托管的Maven网站首先是我们要寻找的。

顺便说一句，Maven的{URL“ https://maven.google.com ”}用于摇篮版本低于4.1和谷歌（）是该较新的形式。另请参阅此文档。

Answer 2

api 'com.android.support:appcompat-v7:24.2.1'
api 'com.android.support:support-v4:24.2.1'

这就是你的问题所在。即使没有 Firebase，这也应该会引起问题。您正在使用 API 28 进行定位和构建，但您的支持依赖项位于 API 24。将它们更改为使用28.0.0.

还要检查您的extension-api项目haxe-firebase并确保它们使用最新的编译和 SDK 版本，以及构建工具版本和支持库版本。
