5 个解决方案

This usually happens in Windows environments when the target folder is "locked".当目标文件夹被“锁定”时，这通常发生在 Windows 环境中。 Eg when you are running your web application (looks like you do) and want to perform a mvn clean .例如，当您运行 Web 应用程序（看起来像您这样做）并想要执行mvn clean 。 The application server/servlet engine locks the files so that mvn clean cannot delete the files because they are locked.应用程序服务器/servlet 引擎锁定文件，以便mvn clean无法删除文件，因为它们已被锁定。 Try to run this command when the web application is not running.尝试在 Web 应用程序未运行时运行此命令。

Edit: This also may happen if you have the target folder open in explorer or editing a text file from target folder, etc.编辑：如果您在资源管理器中打开目标文件夹或编辑目标文件夹中的文本文件等，也可能发生这种情况。

在 Glassfish 服务器的情况下，您只需停止服务器并在运行项目后进行清理和构建，它肯定会工作。确认

If you are using windows system, close all applications (eg file explorer, any file opened in eg notepad which is part of the "target" folder etc.).如果您使用的是 windows 系统，请关闭所有应用程序（例如文件资源管理器、在记事本中打开的任何文件，这些文件是“目标”文件夹的一部分等）。 Basically, Maven is trying to Delete the file but as it is "locked" by some other application, Maven can't access it and hence can't delete it.基本上，Maven 试图删除该文件，但由于它被其他应用程序“锁定”，Maven 无法访问它，因此无法删除它。

Clean the project once and rebuild it.清理一次项目并重建它。 If it is not working just kill the java process and restart the studio如果它不起作用，只需杀死java进程并重新启动工作室

系统重新启动对我有用。请尝试。
