我正在尝试将一个安卓应用程序(С++/Qt)从Windows编译到一个虚拟的Android上。 Android SDK：31 (Android 12) NDK：21.3.6528147 Qt：5.15.2 语言：C++17 显然，编译是针对x86_64处理器的。 Android包生成时编译中断，编译输出如下： 05:00:15: The process "C:\Users\adzol\AppData\Local\Android\Sdk\ndk\21.3.6528147\prebuilt\windows-x86_64\bin\make.exe" exited normally. 05:00:15: Starting: "D:\Qt\5.15.2\android\bin\androiddeployqt.exe" --input C:/Users/adzol/Projects/build-posiflora-pos-Android_Qt_5_15_2_Clang_Multi_Abi_x86_64-Debug/florist/android-florist-deployment-settings.json --output C:/Users/adzol/Projects/build-posiflora-pos-Android_Qt_5_15_2_Clang_Multi_Abi_x86_64-Debug/florist/android-build --android-platform android-31 --jdk "C:/Program Files/java-se-8u42-ri" --gradle Generating Android Package Input file: C:/Users/adzol/Projects/build-posiflora-pos-Android_Qt_5_15_2_Clang_Multi_Abi_x86_64-Debug/florist/android-florist-deployment-settings.json Output directory: C:/Users/adzol/Projects/build-posiflora-pos-Android_Qt_5_15_2_Clang_Multi_Abi_x86_64-Debug/florist/android-build/ Application binary: florist Android build platform: android-31 Install to device: No Warning: QML import could not be resolved in any of the import paths: Pos.Controllers Warning: QML import could not be resolved in any of the import paths: Pos.Managers Warning: QML import could not be resolved in any of the import paths: Pos.Helpers Warning: QML import could not be resolved in any of the import paths: Pos.Models Warning: QML import could not be resolved in any of the import paths: Pos.Enums Warning: QML import could not be resolved in any of the import paths: Pos.DateTimeUtils Warning: QML import could not be resolved in any of the import paths: QZXing Warning: QML import could not be resolved in any of the import paths: Clipboard Warning: QML import could not be resolved in any of the import paths: QtQuick.Extras.Private.CppUtils Warning: QML import could not be resolved in any of the import paths: QtQuick.Extras.Private.CppUtils Starting a Gradle Daemon, 1 incompatible and 11 stopped Daemons could not be reused, use --status for details FAILURE: Build failed with an exception. * What went wrong: A problem occurred configuring root project 'android-build'. > Could not resolve all files for configuration ':classpath'. > Could not resolve com.android.tools.build:gradle:3.6.3.
