android - 错误：无法解决：浓缩咖啡核心和错误：无法解决：跑步者

问题描述

我要建立一个项目。创建项目时，遇到以下错误

ERROR: Failed to resolve: espresso-core
Affected Modules: mvp-app


ERROR: Failed to resolve: runner
Affected Modules: mvp-app

和我的 build.gradle(module) 文件 

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "ir.sabmanage.mvp"
        minSdkVersion 16
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.android.support:design:28.0.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

    implementation 'com.android.support:exifinterface:28.0.0'
    implementation 'com.ss.bottomnavigation:bottomnavigation:1.5.2'
    implementation 'com.squareup.retrofit2:retrofit:2.4.0'
    implementation 'com.squareup.retrofit2:converter-gson:2.1.0'
    implementation 'com.squareup.okhttp3:okhttp:3.10.0'
    implementation 'com.squareup.picasso:picasso:2.71828'
    implementation 'io.reactivex.rxjava2:rxandroid:2.1.1'
    implementation 'io.reactivex.rxjava2:rxjava:2.1.14'
    implementation 'com.squareup.retrofit2:adapter-rxjava2:2.4.0'
}

和我的 build.gradle(project) 文件

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

buildscript {
    repositories {
        google()
        jcenter()
        mavenCentral()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.0'

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

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

    }
}

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

如何修复此错误？有没有人遇到过这个问题？我找到了一个解决方案，但它没有回答我 android studio failed to resolve: runner and failed to resolve: espresso-core and failed to resolve: monitor

解决方案

如果您使用的是 androidx 依赖项，您可能需要替换以下实现：

androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

用这些：

androidTestImplementation 'androidx.test:runner:1.3.0-alpha03'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0-alpha03'
