android - 错误 :Unable to resolve dependency for ':app@debugAndroidTest/compileClasspath' : Could not resolve junit:junit:4. 12

Question

我创建了一个新的 android 项目，它在构建时显示错误

我尝试了现有的答案

• Failed to resolve: com.android.support:appcompat-v7 24.0.1
• 我试图使 android studio 无效并重新启动

错误是

Error:Unable to resolve dependency for ':app@debugAndroidTest/compileClasspath': Could not resolve junit:junit:4.12.

Error:Unable to resolve dependency for ':app@releaseUnitTest/compileClasspath': Could not resolve junit:junit:4.12.

Error:Unable to resolve dependency for ':app@debugUnitTest/compileClasspath': Could not resolve junit:junit:4.12.

Error:Unable to resolve dependency for ':app@debugAndroidTest/compileClasspath': Could not resolve com.google.code.findbugs:jsr305:2.0.1.

我的 gradle 文件的依赖部分

 dependencies 
    {
       implementation 'androidx.appcompat:appcompat:1.0.2'
    testImplementation 'junit:junit:4.12'

    }

我不明白这是我的第一个项目。

我的项目gradle是

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

buildscript {
    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.1'

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

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

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

我的应用程序 gradle 是

apply plugin: 'com.android.application'

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.0"
    defaultConfig {
        applicationId "com.example.myapplication"
        minSdkVersion 28
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}
android
        {
            configurations.all
                    {
                        resolutionStrategy.force 'com.google.code.findbugs:jsr305:1.3.9'
                    }
        }

dependencies
        {
    implementation 'androidx.appcompat:appcompat:1.0.2'
    testImplementation 'junit:junit:4.12'


}

Answer 1

在您的 build.gradle 文件中添加以下存储库，

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

你忘了把这个添加到你的依赖项中

androidTestCompile 'com.google.code.findbugs:jsr305:3.0.0' 

问题是由 espresso library 引起的，如果你不能删除它，请将它添加到你的应用程序 gradle

android
{ 
 configurations.all 
  { 
    resolutionStrategy.force 'com.google.code.findbugs:jsr305:1.3.9' 
  }
}
