Question

我正在尝试构建我的Android Studio项目，但始终收到此“无法解决：com.android.support”错误。

build.gradle的外观如下：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "app.training.linus.trainingapp"
        minSdkVersion 26
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.exercise_card.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-v7:27.1.1'
    implementation 'com.android.support:design:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.1'
    implementation 'com.android.support:support-v4:27.1.1'
    implementation 'com.android.support:cardview-v7:27.1.1'
    implementation 'com.google.android.gms:play-services-plus:15.0.1'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.exercise_card:runner:1.0.2'
    androidTestImplementation 'com.android.support.exercise_card.espresso:espresso-core:3.0.2'
}

另一个gradle文件：

// 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:3.1.3'


        // 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
}

我不知道为什么无法正确构建，下载了正确的SDK版本以及所有内容。

谢谢！

Answer 1

移除

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

似乎已经解决了！

您会告诉我该错误以体面地了解问题吗？通常，如果您更新工作室，则会发生集成问题重新安装Studio并连接SDK 你应该检查 android studio中的依赖项

'dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:design:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.1'
implementation 'com.android.support:support-v4:27.1.1'
implementation 'com.android.support:cardview-v7:27.1.1'
implementation 'com.google.android.gms:play-services-plus:15.0.1'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.exercise_card:runner:1.0.2'
androidTestImplementation 'com.android.support.exercise_card.espresso:espresso-core:3.0.2'

}'

您需要在所有项目中添加项目级别gradle

 maven {
        url "https://maven.google.com"
    }


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

Build.gradle：无法解决：com.android.support
