我发现有人失败了非常相似的问题但是使用 Android Studio/Ubuntu（我使用的是 IntelliJ Community/Windows 10）：other question
我仔细尝试了所有建议，其中 none 解决了我的问题。如果我重新启动 Windows 并且只工作一次，我只会让它恢复工作。
一些建议是：
1 - 关闭工作室并转到问题所在的路径并删除那里的文件夹。
我尝试关闭 IntelliJ，但无法直接删除文件夹
2 - 文件 > 设置 > 构建、执行、部署 > 即时 运行 > 取消选中此复选框（启用即时 运行 热插拔代码）

问题是您有多个 Gradle 进程仍在锁定您的文件。
您可以尝试 运行 gradle --stop，当这恰好停止后台 运行 的任何守护进程时（这通常会有所帮助）。
您还可以通过 运行 gradle --status 检查守护进程的状态。对我来说，这个输出：
No Gradle daemons are running.
Only Daemons for the current Gradle version are displayed.
See https://docs.gradle.org/6.5/userguide/gradle_daemon.html#sec:status
如果你在那里看到什么，那可能是有问题。
使用 --no-daemon 和 --no-parallel 可能会有所帮助，但它们只会隐藏潜在的问题。
在我的情况下，当发生这种情况时，我意识到我在后台有进程 运行，因为测试从未完成。检查所有线程 and/or 协程对未关闭/未完成进程的使用情况。
另一个发生在我身上的案例是当我使用 ProcessBuilder 启动另一个 Java 进程时它没有退出。
我转到我的文件系统并手动删除了该文件。重新启动了我的 android
只需重命名“build”文件夹即可。
就我而言，我在 运行 作为 root 用户在 Linux 中执行 Gradle 命令后遇到了这个错误。
切换回普通用户后，Gradle给我报了上面的错误。当我尝试使用 rm -rf build/ 删除构建目录时，我收到“权限被拒绝”错误。您可以通过以根用户身份删除构建目录来解决此问题。
对我来说，不同用户和组下的文件和权限不足以写入相关目录的文件。
尝试检查项目文件的用户是谁ls -al
如果项目和子目录和文件在不同的用户下。您可以 运行 sudo chown -R [new_owner] [project_folder_name] 标志 -R 递归地更改子文件和子目录的所有者。
您还可以向组添加额外权限（如果用户属于该组）甚至更改组（如果用户不属于该组）。基本思想是给予用户足够的权限 (rwx) 来使用文件。
