我昨天更新了Gradle插件，现在android studio无法构建我的应用了。该应用程序显示以下错误。

我的应用程序级别build.gradle文件如下：

    apply plugin: 'com.android.application'
apply plugin: 'io.fabric'
android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.mvp1stockmeter"

    }
    buildTypes {

        }

    dataBinding
            {
                enabled true
            }
}

我的项目级别的build.gradle文件如下：

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

buildscript {
    repositories {
        google()
        jcenter()
        maven {
            url 'https://maven.fabric.io/public'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.2'
        classpath 'com.google.gms:google-services:4.2.0'
        classpath 'io.fabric.tools:gradle:1.26.1'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

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

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

我也在StackOverflow和google上进行了搜索。但是没有找到任何信息。请帮忙。我被困在这里。

Answer 1

在项目级别build.gradle文件的allprojects {}部分中添加mavenCentral（）已为我解决了此问题。

Answer 2

删除此行：-testInstrumentationRunner“ android.support.test.runner.AndroidJUnitRunner” ...对我有用

Answer 3

在项目级别build.gradle文件的buildScript {}部分中添加mavenCentral（）已为我解决了此问题。感谢您的支持。

Answer 4

我不知道为什么会这样，但是自从昨天（2019年3月21日）以来一直在发生。我认为这是Maven存储库中的问题吗？因为android studio尝试获取该库的网址已关闭。

无论如何，解决方法是“手动”将AS指向缺少的依赖项，并将此行添加到build.gradle的依赖项中{...}

implementation group: 'io.grpc', name: 'grpc-core', version: '1.16.1'

然后同步，然后您可以删除该行。

好吧，我希望有人能解释发生了什么事。

Answer 5

我遇到了以下三种类型的构建错误：

Unable to resolve dependency for ':app@debugUnitTest/compileClasspath': Could not resolve io.grpc:grpc-core:[1.28.0].

与许多与android studio相关的问题一样，

File -> Invalidate Caches / Restart...

是我的把戏。

Answer 6

将mavenCentral（）添加到buildscripts->存储库和allprojects->存储库中，并同步项目。
