无法删除某些子项。这可能是因为进程打开了文件或在目标目录中设置了其工作目录

Jim*_*m C 7 windows intellij-idea gradle kotlin micronaut

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

我发现有人在使用 Android Studio/Ubuntu（我使用的是 IntelliJ Community/Windows 10）时遇到了类似的问题：其他问题

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 Windows 并且只工作一次，我只会让它恢复工作。

其中一些建议是：

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（启用即时运行到热插拔代码）在我的 IntelliJ 中没有这样的选项

3 - gradlew clean 同样的问题

4 - 右键单击目录，单击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 build 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 build 文件夹

问题是您有多个 Gradle 进程仍然持有对您文件的锁定。

gradle --stop当这种情况发生时，您可以尝试运行以停止在 backgorund 中运行的任何守护进程（这通常会有所帮助）。

您还可以通过运行来检查守护程序的状态gradle --status。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

如果你在那里看到一些东西，那可能是一个问题。

使用--no-daemonand--no-parallel可能会有所帮助，但它们只会隐藏潜在的问题。

就我而言，当发生这种情况时，我意识到我的进程在后台运行，因为测试从未完成。检查所有线程和/或协程使用情况是否有未关闭/未完成的进程。

另一种发生在我身上的情况是，当我使用ProcessBuilder启动另一个 Java 进程但它没有退出时。
