android - 无法使用Firebase性能进行编译。 (无法找到方法...)

Question

我正在尝试将Firebase Performance Monitoring添加到我的Android Studio项目中。在按照有关如何将其添加到我的应用程序中的步骤进行操作之后，我无法编译我的应用程序。这是错误:

Error:(1, 0) Unable to find method 'com.google.common.base.Preconditions.checkArgument(ZLjava/lang/String;Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;)V'.
Possible causes for this unexpected error include:

• Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)Re-download dependencies and sync project (requires network)
• The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.Stop Gradle build processes (requires restart)
• Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.

In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.

项目build.gradle:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-alpha7'
        classpath 'com.google.gms:google-services:3.1.0'
        classpath 'com.google.firebase:firebase-plugins:1.1.0'

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

allprojects {
    repositories {
        jcenter()
        google()
        maven {
            url "https://jitpack.io"
        }
    }
}

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

// Define versions in a single place
ext {
    // Sdk and tools
    minSdkVersion = 16
    targetSdkVersion = 26
    compileSdkVersion = 26
    buildToolsVersion = '26.0.0'

    sourceCompatibility = JavaVersion.VERSION_1_8
    targetCompatibility = JavaVersion.VERSION_1_8

    // Version
    versionCode = 1;
    versionName = "0.0.1";

    ...

    // Firebase
    firebaseVersion = '11.0.2'

    ...
}

应用程序build.gradle:

apply plugin: 'com.android.application'
apply plugin: 'com.google.firebase.firebase-perf'

android {
    compileSdkVersion rootProject.ext.compileSdkVersion
    buildToolsVersion rootProject.ext.buildToolsVersion

    defaultConfig {
        applicationId "REMOVED"
        minSdkVersion rootProject.ext.minSdkVersion
        targetSdkVersion rootProject.ext.targetSdkVersion
        versionCode rootProject.ext.versionCode
        versionName rootProject.ext.versionName
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

        vectorDrawables.useSupportLibrary = true
        dataBinding.enabled = true
    }
    compileOptions {
        sourceCompatibility = rootProject.ext.sourceCompatibility
        targetCompatibility = rootProject.ext.targetCompatibility
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    ...
    
    // Firebase
    compile "com.google.firebase:firebase-core:$rootProject.firebaseVersion"
    compile "com.google.firebase:firebase-perf:$rootProject.firebaseVersion"

    ...
}

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

您的buildscript依赖项中可能有firebase。

问题是我的buildscript依赖项中有firebase，所以看起来像这样:

buildscript {
    ext.kotlin_version = '1.1.3-2'
    apply from: 'dependencies.gradle'
    repositories {
        ...
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-alpha6'
        classpath ('com.google.firebase:firebase-plugins:1.1.0') //the firebase line
        ....
    }
}

以此替换firebase classpath行:

classpath ('com.google.firebase:firebase-plugins:1.1.0') {
    exclude group: 'com.google.guava', module: 'guava-jdk5'
}

然后，您必须清理项目，杀死gradle守护程序，然后重新启动android studio。
