无法解决：com.firebase:firebase-jobdispatcher:0.5.0

Question

我正在尝试构建项目，但这是我收到的错误消息。

    Error:(32, 13) Failed to resolve: com.firebase:firebase-jobdispatcher:0.5.0
    Show in File
    Show in Project Structure dialog

    Error:Failed to resolve: com.android.databinding:compiler:2.2.3

这里是应用模块的构建文件：-

apply plugin: 'com.android.application'

android {
compileSdkVersion 24
buildToolsVersion '24.0.0'

defaultConfig {
    applicationId "com.example.android.sunshine"
    minSdkVersion 10
    targetSdkVersion 24
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
    }
}

dataBinding.enabled = true
}

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:appcompat-v7:24.2.1'

compile 'com.android.support:recyclerview-v7:24.2.1'
compile 'com.android.support:preference-v7:24.2.1'

compile 'com.android.support.constraint:constraint-layout:1.0.0-beta3'

compile 'com.firebase:firebase-jobdispatcher:0.5.0'

// Instrumentation dependencies use androidTestCompile
// (as opposed to testCompile for local unit tests run in the JVM)
androidTestCompile 'junit:junit:4.12'
androidTestCompile 'com.android.support:support-annotations:24.2.1'
androidTestCompile 'com.android.support.test:runner:0.5'
androidTestCompile 'com.android.support.test:rules:0.5'
}

这里是完整项目模块的构建文件：-

buildscript {
repositories {
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:2.2.3'

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

allprojects {
String osName = System.getProperty("os.name").toLowerCase();
if (osName.contains("windows")) {
    buildDir = "C:/tmp/${rootProject.name}/${project.name}"
}
repositories {
    jcenter()
}
}

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

这里是 AndroidManifest.xml 文件：-

我该如何解决这个问题？我也没有在互联网上获得任何资源。

Answer 1

图书馆的github有提到：

如果你没有依赖 com.google.android.gms:play-services-gcm，将以下内容添加到您的 build.gradle 的依赖部分：

compile 'com.firebase:firebase-jobdispatcher:0.5.2'

否则添加以下内容：

compile 'com.firebase:firebase-jobdispatcher-with-gcm-dep:0.5.2'

而且我在你的 gradle 文件上看不到任何对 gms 的依赖。所以你应该使用第二个依赖。

更新（2017 年 5 月）：第二个依赖项已从文档中删除。它现在应该只使用这个依赖： compile 'com.firebase:firebase-jobdispatcher:0.5.2'.
