android - 将 Android Studio 更新到 3.1.3 后依赖项出现一些错误

Question

您好，我在构建时遇到了一些错误... 我是 android studio 的新手 在我将我的 android studio 更新到 3.1.3 之前我没有问题...... 现在我在 gradle build 上播报关于 Unable to resolve dependency for ... 的错误

这是我的 build.gradle(Module: app)

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.example.shoaib.newsletters"
        minSdkVersion 18
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.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-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.0'
    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'

    compile 'com.tomerrosenfeld.customanalogclockview:custom-analog-clock-view:1.1'
    compile 'com.android.volley:volley:1.1.0'
    compile 'com.squareup.picasso:picasso:2.5.2'
}

和我的 build.gradle(Project:)

// 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
}

还有错误

Configuration 'compile' is obsolete and has been replaced with 'implementation' and 'api'.
It will be removed at the end of 2018. For more information see: http://d.android.com/r/tools/update-dependency-configurations.html

请告诉我如何解决这些问题...

Answer 1

当您使用 appcompact-v7:26.1.0 时

你的约束布局版本必须是

implementation 'com.android.support.constraint:constraint-layout:1.0.2'

测试应该是

androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
