无法使用Java删除Windows中的文件

Question

我一直在尝试使用Java IO file.delete()API 删除Windows操作系统中的文件.但是它失败并返回false.相同的代码就像Ubuntu中的魅力一样.

我已经验证该文件的权限允许程序删除它.此外,文件的所有输入和输出流都已尝试使用资源打开.

try (InputStream in = new FileInputStream(localFile); OutputStream out = new FileOutputStream(destinationFileName))

使用我已经测试过的调试器,发现在代码行中我删除了它true为以下API调用返回的文件.

file.exists()
file.canRead();
file.canWrite();
file.canExecute();

我甚至尝试System.gc()在调用delete之前添加,以确保所有流都关闭.

不确定这是否是有用的信息,但我甚至尝试使用Apache commons FileUtils.forceDelete(file)方法,它也失败了.

那我在这里错过了什么？

更新:

通过使用Files.delete(Paths.get(file.getAbsolutePath()))我得到以下错误.

java.nio.file.FileSystemException: C:\Users\thuvvareka\Desktop\temp\in\sd.xml: The process cannot access the file because it is being used by another process.

Answer 1

使用Files.delete(filePath)而不是file.delete()asfile.delete()在 Windows 上的权限方面存在一些问题。
