【问题描述】：
我正在尝试在 AppCenter.ms 中构建颤振应用程序，但我遇到了清理中间文件夹的 gradle 命令。
我已按照这些教程进行设置：
- https://www.rocksolidknowledge.com/articles/using-appcenter-for-flutter-projects
- https://buildflutter.com/deploying-flutter-apps-via-appcenter/
- https://medium.com/@subodhpushpak/flutter-continuous-build-deployment-using-appcenter-e105d00e6f9c
我添加了一个名为 appCenter 的 productFlavor 来容纳这个库：https://pub.dev/packages/flutter_appcenter_bundle
这是我的appcenter-post-clone.sh：
#!/usr/bin/env bash
#Place this script in project/android/app/
cd ..
# fail if any command fails
set -e
# debug log
set -x
cd ..
git clone -b stable https://github.com/flutter/flutter.git
export PATH=`pwd`/flutter/bin:$PATH
flutter channel stable
flutter doctor
# prevent missing flutter.jar error
flutter precache `pwd`/flutter/bin/cache/artifacts/engine
# Set APP_CENTER_VERSION_MODIFIER if you want to modify the version name
# to x.y.z-${APP_CENTER_VERSION_MODIFIER}
BUILD_NAME=$(grep -E '^version' pubspec.yaml | cut -d':' -f2 | tr -d '[:space:]')
if [ ! -z "$APPCENTER_BUILD_ID" ]
then
BUILD_NAME=${BUILD_NAME}.${APPCENTER_BUILD_ID}
fi
if [ ! -z "$APP_CENTER_VERSION_MODIFIER" ]
then
BUILD_NAME=${BUILD_NAME}-${APP_CENTER_VERSION_MODIFIER}
fi
flutter build apk --debug --flavor appCenter
flutter build apk --release --flavor appCenter --build-name=${BUILD_NAME} -t lib/main.dart
mkdir -p android/app/build/outputs/apk/
mv build/app/outputs/flutter-apk/app-appcenter-release.apk $_
appcenter-post-clone.sh 脚本完成后运行 gradle 时出现错误：

问题：
Transform's input file does not exist: /.../intermediates/flutter/appCenterDebug/libs.jar
我遇到了这个 SO 帖子： Generate signed apk fails with build\app\intermediates\flutter\profile\libs.jar (The system cannot find the path specified) 指向https://github.com/flutter/flutter/issues/58247#issuecomment-636500680
“解决方案”是先运行flutter build apk --debug，然后运行flutter build apk --release
理论上，这将为appCenterDebug 和appCenterRelease 生成带有所需文件的intermediates 目录。
通过运行gradlew lintAppCenterDebug 在本地对其进行测试，然后运行gradlew lintAppCenterRelease。
两个颤振命令都成功构建。
问题出在 gradle 开始运行时这一行：
[command]/.../android/gradlew -DAPPCENTER_BUILD_VERSION=42 -DMOBILECENTER_BUILD_VERSION=42 -p android clean :app:assembleAppCenterRelease :app:lintAppCenterRelease
它在命令中进行了清理，删除了intermediates 目录（所以这个/.../appCenterDebug/libs.jar 不再存在）并且只构建:app:...Release 版本。然后它继续并中断并给出input file does not exist 错误。
如何解决这个问题？
如何从 gradle 命令中删除 clean 部分？ （我在任何地方都找不到）
- 我已经在本地测试了这个确切的命令，但失败了。
- 通过运行两个 gradle lint 命令重新生成
intermediates内容 - 运行相同的 gradle 命令但没有
clean并且它可以工作。
在本地和 appcenter 中调试、发布构建工作正常（直到 gradle 运行并删除所需的文件）
