Question

我一直在尝试在任何目录中创建一个ANYWHERE文件时遇到很多麻烦，而且我没有运气。

@SuppressWarnings("resource") //Install the modpack and create files
public void installModpack(){
    File f = new File("\\ultima");
    f.mkdirs();
}

这是堆栈跟踪：

Answer 1

堆栈跟踪与您问题中的代码不匹配。 stacktrace表示installModpack正在调用File.createNewFile，但在您的代码中没有此类调用。

异常消息似乎在说它正在尝试创建＆＃34; C：\ Users \ Drew \ AppData \ Roaming＆＃34;，或者在该目录中创建一个文件。这与路径名＆＃34; \ ultima＆＃34;不匹配您显然正在尝试使用它。

如果没有看到实际的代码，我们无法告诉您真正的解决方案是什么，但我会：

检查是否＆＃34; C：\ Users \ Drew \ AppData \ Roaming＆＃34;使用其他工具存在。
检查源代码和/或使用调试器运行代码，找出您实际使用的installModpack方法。

我自己回答了这个问题。我稍后在代码中遇到的一些代码搞砸了：p 正在寻找的任何人的正确用法是：文件f =新文件（System.getenv（“APPDATA”）+“/。multima”）; f.mkdirs（）;
