android - IOException 无法删除路径

Question

我在我的一个项目中遇到了这个错误。

FAILURE: Build failed with an exception.

• What went wrong:

  Execution failed for task ':app:transformClassesWithDesugarForDevServerDebug'. com.android.build.api.transform.TransformException: java.io.IOException: Could not delete path 'D:\Android\Projects\uralenergo\app\build\intermediates\transforms\desugar\devServer\debug\1.jar'.

• 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 9s

我经常在这个项目上工作，当我尝试在手机上运行我的应用程序时，我厌倦了在 40% 的情况下看到这个错误。

如果我执行 Rebuild Project，错误就会消失并编译应用程序。
但是在构建应用程序2-3次后，再次出现此错误。

这个项目很大，我不能把时间浪费在重建项目上。
我试图手动删除此文件夹。但这对我没有帮助。

发生这种情况是由于多种原因，例如当您升级操作系统或更改项目路径或再次下载工作室时，需要删除构建文件夹中的先前文件。因此，在这种情况下，启动 Android studio as --> 以管理员身份运行 .

然后右键单击工作室项目中的构建文件夹，然后单击在资源管理器中显示。 现在删除构建文件夹 .如果需要管理员权限，请单击复选框并将其删除。现在重建项目并运行项目。
