Build Error: `Failed to resolve: leakcanary-android` after updating to Gradle 4.4

Failed to resolve: leakcanary-android

升级到 Grade 到 4.4 后出现此构建错误。

我启动了一个全新的 Android Studio 项目,但遇到了同样的错误。还有其他人遇到同样的问题吗?

我正在使用 Android Studio 3.1。以下是我全新项目的代码。

build.gradle 应用插件:'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.xi_zz.myapplication"
        minSdkVersion 21
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:27.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'

    debugImplementation 'com.squareup.leakcanary:leakcanary-android:1.5.4'
    releaseImplementation 'com.squareup.leakcanary:leakcanary-android-no-op:1.5.4'
}

build.gradle(顶级) 构建脚本{

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.0'


        // 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
}

gradle-wrapper.properites

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip

我添加到这个新项目的唯一代码是下面的代码,在 https://github.com/square/leakcanary 中有说明。

debugImplementation 'com.squareup.leakcanary:leakcanary-android:1.5.4'
releaseImplementation 'com.squareup.leakcanary:leakcanary-android-no-op:1.5.4'

这是 leakcanary 中的错误吗?

不太确定。这可能是 Gradle 4.4 的问题,因为我在更新到 Gradle 4.5 后解决了它。

问题是空格

试试这个

调试实现'com.squareup.leakcanary:leakcanary-android:1.5.4' 发布实施'com.squareup.leakcanary:leakcanary-android-no-op:1.5.4'
