Flutter 3.29.0升级后运行Android项目报Gradle依赖解析失败

将Flutter从3.27.1升级至3.29.0稳定版后，本地无法运行Android项目，即使新建项目执行以下命令：

mkdir flutt
cd flutt
flutter create . --platforms=android
flutter run

依然构建失败，报错信息如下：

FAILURE: Build failed with an exception.

• What went wrong:

1. 修复项目根目录settings.gradle配置 #

确保文件包含完整的仓库定义，替换为以下内容：

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

2. 修复android/build.gradle配置 #

更新文件中的仓库和依赖配置：

buildscript {
    ext.kotlin_version = '1.9.24'
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath "com.android.tools.build:gradle:8.7.3"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

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

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

tasks.register("clean", Delete) {
    delete rootProject.buildDir
}

3. 清除缓存并重新构建 #

执行以下命令清理缓存后重新运行项目：

flutter clean
rm -rf ~/.gradle/caches
flutter pub get
flutter run

4. 确认Gradle版本兼容性 #

通过Android Studio的File > Settings > Build, Execution, Deployment > Build Tools > Gradle检查本地Gradle版本是否支持8.7.3，若缺失会自动下载对应版本。
