無法解決：com.android.support:support-compat:27.2.0

Question

我的應用gradle中的依賴項存在問題：

apply plugin: 'com.android.application'

android {
compileSdkVersion 27
defaultConfig {
    applicationId "fr.android.MyApp"
    minSdkVersion 16
    targetSdkVersion 27
    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(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support:appcompat-v7:25.1.1'
implementation 'com.android.support:animated-vector-drawable:27.1.1'
implementation 'com.android.support:support-compat:27.2.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
implementation 'com.google.firebase:firebase-auth:11.6.0'
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'
}
apply plugin: 'com.google.gms.google-services'

出現錯誤的行是：

implementation 'com.android.support:animated-vector-drawable:27.1.1'

它說：無法解決：com.android.support:animated-vector-drawable:27.1.1

和：

我還得到：配置'compile'已過時，並已由'implementation'和'api'代替。 它將在2018年底刪除。

這是我的build.gradle：

// 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:3.1.2'


    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
    classpath 'com.google.gms:google-services:3.1.1'
      }
   }

allprojects {
repositories {
    google()
    jcenter()
   }
}

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

有關如何解決此問題的任何想法？ 提前致謝。

Answer 1

這是因為您使用了舊版本的appcompat庫，即：

implementation 'com.android.support:appcompat-v7:25.1.1'

將其版本從v7：25.1.1更改為27.1.1

例：

dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:animated-vector-drawable:27.1.1'
implementation 'com.android.support:support-compat:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
implementation 'com.google.firebase:firebase-auth:11.6.0'
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'
}

更改后同步項目

Answer 2

所有com.android.support必須使用完全相同的版本規范

您可以使用animated-vector-drawable:27.1.1在版本27.1.1和support-compat的版本為27.2.0 。 您應該使它們具有相同的版本。
