Question

我使用FileSystem修改zip文件中的属性文件

public boolean processZip()
{
    boolean wasModified = false;
    Path zipFilePath = Paths.get(this.getZipFileName());

    try (FileSystem fs = FileSystems.newFileSystem(zipFilePath, null))
    {
        Logger.info("Processing zip: #0",
            this.getZipFileName());

        Path source = fs.getPath(
            "/some/path/some.properties");

        // Delete old properties file.
        Files.delete(source);
        this.createPropertiesFile(source);
        wasModified = true;
    }
    catch (NoSuchFileException e)
    {
        Logger.info("Properties file not found.");
    }
    catch (Exception e)
    {
        Logger.error("There was an error updating the properties in zip: " +
                this.getZipFileName(),
            e);
    }

    return wasModified;
}

protected void createPropertiesFile(Path dst) throws IOException
{
    try (BufferedWriter bw = new BufferedWriter(
            new OutputStreamWriter(Files.newOutputStream(dst))))
    {
        bw.write(this.getProperties().getValues());
    }
    catch (Exception e)
    {
        Logger.error("There was an error creating the properties in zip: " +
                this.getInputJarFileName(),
            e);
    }
}

但是偶尔会出现以下堆栈跟踪的窗口失败：

ERROR: There was an error updating the properties in zip: C:\Apps\Test\some.zip
java.nio.file.FileSystemException: C:\Apps\Test\some.zip: The process cannot access the file because it is being used by another process.

问题是，该文件被先前的进程复制（该进程在修改zip文件时结束）。所以我不知道在Windows中可以使用该文件的内容。起初我认为可能是防病毒软件，但即使关闭防病毒软件也会发生这种情况。

我不确定是否还有其他措施可以防止这种情况发生。它不是那么频繁，但偶尔会发生。

它有管理员权限，我试过爆炸拉链，修改文件并将其压缩回来。这只会使问题更加频繁。我也尝试过Apache commons FileUtils.forceDelete（file）。

我有什么遗失的东西吗？

无法使用Java
