升级Android Studio Electric Eel后Gradle插件找不到求助

核心问题分析 #

1. Android Studio Electric Eel要求Android Gradle插件（AGP）版本≥7.4.0，你当前使用的7.1.2版本过低，且plugins块未配置Google仓库，导致插件无法被检索到。
2. Gradle版本（8.0.2）与AGP版本（7.1.2）不兼容，同时存在配置冗余、依赖版本不匹配的问题。

正确配置文件 #

1. settings.gradle（需补充/修改）

pluginManagement {
    repositories {
        gradlePluginPortal()
        google()
        mavenCentral()
    }
}
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
    }
}
rootProject.name = "connect_app"
include ':app'

2. android/build.gradle

plugins {
    id 'com.android.application' version '7.4.2' apply false
    id 'com.android.library' version '7.4.2' apply false
    id 'org.jetbrains.kotlin.android' version '1.7.20' apply false
    id 'com.google.gms.google-services' version '4.4.0' apply false
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
    project.evaluationDependsOn(':app')
}

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

3. app/build.gradle

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
    keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '2'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.1'
}

plugins {
    id 'com.android.application'
    id 'org.jetbrains.kotlin.android'
    id 'com.google.gms.google-services'
}

apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

android {
    compileSdkVersion 33

    defaultConfig {
        applicationId "com.elearning.connect"
        minSdkVersion 23
        targetSdkVersion 33
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        multiDexEnabled true
    }

    signingConfigs {
        release {
            keyAlias keystoreProperties['keyAlias']
            keyPassword keystoreProperties['keyPassword']
            storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
            storePassword keystoreProperties['storePassword']
        }
    }

    buildTypes {
        release {
            signingConfig signingConfigs.release
        }
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    kotlinOptions {
        jvmTarget = '1.8'
    }

    buildFeatures {
        viewBinding true
    }
}

flutter {
    source '../..'
}

dependencies {
    implementation 'com.android.support:multidex:1.0.3'
    implementation platform('com.google.firebase:firebase-bom:32.7.0')
    implementation 'com.google.firebase:firebase-analytics'
    implementation 'com.google.firebase:firebase-messaging'
}

关键修改说明 #

• 插件版本适配：将AGP升级到7.4.2（完全兼容Electric Eel），同步升级Kotlin和Google Services插件版本，避免版本冲突。
• 仓库配置：在settings.gradle中配置pluginManagement，确保Gradle能从Google仓库获取AGP插件，解决插件找不到的核心问题。
• 冗余清理：移除app/build.gradle中重复的插件应用、compileOptions配置，将属性配置移到文件开头，避免作用域异常。
• 依赖更新：升级Firebase BOM版本到32.7.0，确保与新版AGP兼容。
