集成Android Alarm Manager Plus后构建失败：appcompat-1.7.0.aar转换错误

集成Android Alarm Manager Plus插件时的构建错误问题
我开发了一款重复提醒应用Rem，在尝试集成Android Alarm Manager Plus Flutter插件时遇到构建错误。该插件的环境要求如下：
- Flutter >=3.3.0
- Dart >=2.18.0 <4.0.0
- Android
compileSDK34 - Java 17
- Android Gradle Plugin（AGP）>=8.3.0
- Gradle wrapper >=8.4
我已满足大部分要求：更新了Flutter版本，修改gradle-wrapper.properties中的distributionUrl为Gradle 8.4，在项目根目录的build.gradle的dependencies中添加classpath "com.android.tools.build:gradle:8.3.0"以更新AGP。此时项目构建正常，但添加插件相关代码后，构建失败，报错信息如下：

我的app模块build.gradle配置如下：
plugins { id "com.android.application" id "kotlin-android" id "dev.flutter.flutter-gradle-plugin" } def localProperties = new Properties() def localPropertiesFile = rootProject.file('local.properties') if (localPropertiesFile.exists()) { localPropertiesFile.withReader('UTF-8') { reader -> localProperties.load(reader) } } def flutterVersionCode = localProperties.getProperty('flutter.versionCode') if (flutterVersionCode == null) { flutterVersionCode = '1' } def flutterVersionName = localProperties.getProperty('flutter.versionName') if (flutterVersionName == null) { flutterVersionName = '1.0' } android { namespace "rem.reminds.you" compileSdkVersion 34 ndkVersion flutter.ndkVersion compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 } kotlinOptions { jvmTarget = '1.8' } sourceSets { main.java.srcDirs += 'src/main/kotlin' } defaultConfig { // TODO: Specify your own unique Application ID applicationId "rem.reminds.you" minSdkVersion 24 targetSdkVersion flutter.targetSdkVersion versionCode flutterVersionCode.toInteger() versionName flutterVersionName } buildTypes { release { // TODO: Add your own signing config for the release build. // Signing with the debug keys for now, so `flutter run --release` works. signingConfig signingConfigs.debug } } } flutter { source '../..' } dependencies {}
我尝试过以下解决方案，但均未彻底解决问题：
- 添加multidex支持
- 尝试降级appcompat版本，但不知道具体操作方法
- 将minSdkVersion从21升级到24，仅部分缓解错误
此外，VS Code弹出以下警告：
Project android: Unsupported Java Runtime: The Java version: 17, that is selected for the project is not supported by Gradle 7.2.The IDE will attempt to use Gradle 8.7 to gather the project information. Possible solutions: * Upgrade your Gradle version on your project * Select Java Runtime 16 (or below), on Build > Gradle Execution settings, to avoid this problem!
我明明已经配置了Gradle 8.4，但警告显示项目使用的是Gradle 7.2，这可能是问题根源，但我不清楚具体原因。
