无法删除部分子项。这可能是因为进程打开了文件或将其工作目录设置在目标目录中

【中文标题】无法删除部分子项。这可能是因为进程打开了文件或将其工作目录设置在目标目录中

【英文标题】：Failed to delete some children. This might happen because a process has files open or has its working directory set in the target directory

【问题描述】：

由于某种未知原因，每当我在启动笔记本后运行gradle clean build 时，它都会按预期工作。当我第二次尝试时，我总是得到

Unable to delete directory 'C:\_d\mycompany\WSs\demo\build'
  Failed to delete some children. This might happen because a process has files open or has its working directory set in the target directory.

我发现有人在使用 android Studio/Ubuntu（我正在使用 IntelliJ Community/Windows 10）时遇到了非常相似的问题：other question

我仔细尝试了所有建议，但没有一个能解决我的问题。如果我重新启动我的 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（启用即时运行以热交换代码） 我的 IntelliJ 中没有这样的可选项

3 - gradlew 清洁 同样的问题

4 - 右键单击​​目录，单击将出现的上下文菜单上的属性，然后取消选中“只读”属性。之后，单击“应用”以应用更改。 我是管理员，但我无法更改此类文件夹属性。

5 - 在 Windows 中以管理员身份运行 android studio 对我有用。 同样的问题

以及在 IntelliJ 中看到的构建文件夹

***已编辑

我没有找到如何解决它。现在正在发生一个我刚刚从micronaut克隆的项目

虽然我是 Windows 管理员，但我无法删除构建文件夹

【参考方案1】：

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，当这种情况发生时会停止在后台运行的任何守护程序（这通常会有所帮助）。

您还可以通过运行gradle --status 检查您的守护进程的状态。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，那可能是个问题。

使用--no-daemon 和--no-parallel 可能会有所帮助，但它们只会隐藏根本问题。

在发生这种情况时，我意识到我有进程在后台运行，因为测试从未完成。检查您的所有线程和/或协程使用情况是否有未关闭/未完成的进程。

当我使用 ProcessBuilder 启动另一个 Java 进程但它没有退出时，我遇到了另一种情况。

【讨论】：

谢谢，但它仍在发生。有趣的是，以前从未发生过相同的笔记本和 gradle 安装。它开始只发生在 micronaut 项目中

那么很可能是Micronaut资源泄露导致某些进程无法停止。

完全不知道出了什么问题。我的公司笔记本电脑遇到了这个问题，我无法以管理员身份登录。今天我的个人笔记本电脑也遇到了同样的问题，显然我是管理员。我安装了一个免费工具，以找出哪个进程阻止了这个文件夹，它指向 java.exe 我杀死了这个进程，但我仍然无法删除该文件夹。只有在我关闭 IntelliJ 和 Visual Studio Code 之后，我才终于设法删除了该文件夹。很奇怪的问题。顺便说一句，我只对包含 micronaut 依赖项的 gradle 项目有这个问题。

哦，如果你在IDEA中开启了增量编译，就会出现这个问题。

【参考方案2】：

尝试重新启动系统。有时没有其他问题，但会出现上述错误

【讨论】：

对我来说是它的作品。尝试接受答案后，所以我发布了。

【参考方案3】：

我转到我的文件系统并手动删除了该文件。重启了我的安卓
