【问题描述】：

当我在我的项目中使用 hilt 时，我遇到了这个问题：

A problem occurred evaluating project ':app'.
    > Failed to apply plugin 'dagger.hilt.android.plugin'.
        > Could not create plugin of type 'HiltGradlePlugin'.
            > Could not generate a decorated class for type HiltGradlePlugin.
                > com/android/build/gradle/BaseExtension

 Unable to load class 'com.android.build.gradle.BaseExtension'.
 This is an unexpected error. Please file a bug containing the idea.log file.

主要问题是：无法应用插件'dagger.hilt.android.plugin'。

这是我的 build.gradle（模块）文件：

plugins 
    id 'com.android.application'
    id 'org.jetbrains.kotlin.android'

apply plugin: 'kotlin-kapt'
apply plugin: 'dagger.hilt.android.plugin'

android 
    compileSdk 30

    defaultConfig 
        applicationId "net.holosen.hiltdaggerapp"
        minSdk 21
        targetSdk 30
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    

    buildTypes 
        release 
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        
    
    compileOptions 
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    
    kotlinOptions 
        jvmTarget = '1.8'
    


dependencies 

    implementation 'androidx.core:core-ktx:1.6.0'
    implementation 'androidx.appcompat:appcompat:1.3.1'
    implementation 'com.google.android.material:material:1.4.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.1.1'
    testImplementation 'junit:junit:4.13.2'
    androidTestImplementation 'androidx.test.ext:junit:1.1.3'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'


    kapt "com.google.dagger:hilt-android-compiler:2.38.1"

    // Dagger Core
    implementation "com.google.dagger:dagger:2.38.1"
    kapt "com.google.dagger:dagger-compiler:2.38.1"

// Dagger Android
    api 'com.google.dagger:dagger-android:2.38.1'
    api 'com.google.dagger:dagger-android-support:2.37'
    kapt 'com.google.dagger:dagger-android-processor:2.38.1'

// Dagger - Hilt
    implementation 'com.google.dagger:hilt-android:2.38.1'
    kapt 'com.google.dagger:hilt-compiler:2.38.1'

    // For instrumentation tests
    androidTestImplementation 'com.google.dagger:hilt-android-testing:2.38.1'
    kaptAndroidTest 'com.google.dagger:hilt-compiler:2.38.1'

    // For local unit tests
    testImplementation 'com.google.dagger:hilt-android-testing:2.38.1'
    kaptTest 'com.google.dagger:hilt-compiler:2.38.1'

kapt 
    correctErrorTypes true

还有我的 build.gradle（项目）文件：

buildscript 
    repositories 
        mavenCentral()
    
    dependencies 
        classpath 'com.google.dagger:hilt-android-gradle-plugin:2.38.1'
    

task clean(type: Delete) 
    delete rootProject.buildDir

这是 settings.gradle 文件：

pluginManagement 
    repositories 
        gradlePluginPortal()
        google()
        mavenCentral()
    
    plugins 
        id 'com.android.application' version '7.1.0-alpha12'
        id 'com.android.library' version '7.1.0-alpha12'
        id 'org.jetbrains.kotlin.android' version '1.5.31'
        id 'dagger.hilt.android.plugin' version '2.38.1'
    

dependencyResolutionManagement 
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories 
        google()
        mavenCentral()
    

rootProject.name = "HiltDaggerApp"
include ':app'

我的参考是 'https://dagger.dev/hilt/gradle-setup.html' 中的 Gradle Build Setup。

gradle-wrapper.properties 文件：

#Sun Sep 26 12:17:22 IRST 2021
distributionBase=GRADLE_USER_HOME
distributionUrl=https\://services.gradle.org/distributions/gradle-7.2-bin.zip
distributionPath=wrapper/dists
zipStorePath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME

【参考方案1】：

这是我遇到同样问题时找到的解决方案，你可以试试吗？

我在 settings.gradle 中添加了一个 resolutionStrategy，如下所示。

 pluginManagement 
        repositories ...
        plugins  ...
     resolutionStrategy 
            eachPlugin 
                if( requested.id.id == 'dagger.hilt.android.plugin') 
                    useModule("com.google.dagger:hilt-android-gradle-plugin:2.39.1")
                
            
        
    

然后，当我将如下所示的 hilt 插件添加到模块级 build.gradle 文件中时，它已正确更新。

plugins
...
id 'dagger.hilt.android.plugin'

这对我有用！但我不明白为什么我们需要这样做......
