为什么AS要在flutter更新后编译项目

Question

FAILURE：构建失败并出现异常。 刚刚更新到 1.5.4-hotfix.2 现在我的项目没有编译，但我的同事使用相同的版本没有问题

控制台输出

Launching lib\main.dart on SM G955F in debug mode...
Initializing gradle...
Resolving dependencies...
Running Gradle task 'assembleDebug'...

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:processDebugResources'.
> Android resource linking failed

• 尝试： 使用 --stacktrace 选项运行以获取堆栈跟踪。使用 --info 或 --debug 选项运行以获得更多日志输出。运行 --scan 以获得完整的见解。

• 通过gradle url获得更多帮助

Gradle 失败可能是因为这个 Flutter 应用中的 AndroidX 不兼容。 请参阅 [googleHref][2] 了解有关该问题以及如何解决该问题的更多信息。

在您的项目中执行flutter clean 命令，以清除以前编译缓存中的所有内容
