Flutter生成的Android项目集成Chaquopy后Gradle Sync失败求助

我在Flutter生成的Android项目里尝试使用Chaquopy插件，由于Chaquopy暂无Flutter直接支持，所以选择在Android子项目中集成。我已经逐行按照Chaquopy官方文档操作，但仍出现Gradle同步失败、无法下载Chaquopy插件的问题。以下是我的配置文件及错误日志，恳请帮忙排查（我是编程新手，对这类问题了解有限）。

Settings.gradle内容 #

include ':app'

def localPropertiesFile = new File(rootProject.projectDir, "local.properties")
def properties = new Properties()

assert localPropertiesFile.exists()
localPropertiesFile.withReader("UTF-8") { reader -> properties.load(reader) }

def flutterSdkPath = properties.getProperty("flutter.sdk")
assert flutterSdkPath != null, "flutter.sdk not set in local.properties"
apply from: "$flutterSdkPath/packages/flutter_tools/gradle/app_plugin_loader.gradle"

项目级Build.gradle内容 #

buildscript {
    ext.kotlin_version = '1.6.10'
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.2.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}
plugins {
    id 'com.chaquo.python' version '12.0.1' apply false
}


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

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

解决步骤 #

1. 修复插件仓库配置
   错误显示Gradle尝试从已停止服务的JCenter下载插件，需在项目级build.gradle中明确指定插件仓库为MavenCentral：

   pluginManagement {
       repositories {
           gradlePluginPortal()
           mavenCentral()
           google()
       }
   }
   
   plugins {
       id 'com.chaquo.python' version '12.0.1' apply false
   }
   

2. 移除重复配置
   应用级build.gradle的defaultConfig中重复设置了buildPython，保留一行即可：

   python {
       buildPython "C:/Users/super/AppData/Local/Programs/Python/Python310/python.exe"
   }
   

3. 检查网络连接
   "Read timed out"说明网络请求超时，确保网络能正常访问Maven仓库，必要时切换网络或配置代理。

4. 清理Gradle缓存
   删除项目根目录下的.gradle文件夹，重新执行Gradle同步，避免缓存干扰。
