重新安装 Windows 后 Flutter 构建失败

Question

我重新安装了 Windows 和 AndroidStudio，现在我的项目出现此构建错误。

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:signingConfigWriterDebug'.
> java.nio.file.AccessDeniedException: E:<theprojectpath>\build\app\intermediates\signing_config\debug\out\signing-config.json

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 1s
Finished with error: Gradle task assembleDebug failed with exit code 1

Answer 1

好的，我修好了：

1. 删除 .android 文件夹中的 build-cache 和缓存文件夹。 通常位于此处 C:\Users\username\.android

2. 删除你的flutter项目文件夹中的build文件夹。 (...)\flutter_project_name\build
