android - 找不到 com.android.tools.build :gradle:4. 4

Question

我刚刚将 gradle 从 3.0.1 迁移到 4.4。现在 Android Studio 显示 gradle build failed 显示以下错误。

Caused by: org.gradle.internal.resolve.ModuleVersionNotFoundException: Could not find com.android.tools.build:gradle:4.4. Searched in the following locations: https://jcenter.bintray.com/com/android/tools/build/gradle/4.4/gradle-4.4.pom https://jcenter.bintray.com/com/android/tools/build/gradle/4.4/gradle-4.4.jar https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/4.4/gradle-4.4.pom https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/4.4/gradle-4.4.jar

项目级 build.gradle 文件如下

 buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        //classpath 'com.android.tools.build:gradle:3.0.1'
        //replaced by 4.4 below
        classpath 'com.android.tools.build:gradle:4.4'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
        mavenCentral()
        jcenter()
        google()
    }
}

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

项目结构如下图。

您混淆了插件版本和 distributionUrl。插件版本应为 classpath 'com.android.tools.build:gradle:3.0.1' 或 com.android.tools.build:gradle:3.1.0。阅读 Android Plugin for Gradle Release Notes .

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
    }
}

和 distributionUrl 到 GradleWrapper。

distributionUrl = https\://services.gradle.org/distributions/gradle-4.4-all.zip

Android 上当前最新的版本 3 gradle 插件可用，您必须使用 classpath 'com.android.tools.build:gradle:3.1.0'。
