java.io.FileNotFoundException :(没有这样的文件或目录)从eclipse运行时

我正在写一个文件,想要控制台输出,

// TODO Create a game engine and call the runGame() method
public static void main(String[] args) throws Exception { 
    NewGame myGame = new TheGame().new NewGame();
    myGame.runGame();
    PrintStream out = new PrintStream(new FileOutputStream("output.txt"));
    System.setOut(out);
}

这给了我控制台输出,但它抛出以下异常:

java.io.FileNotFoundException: TheGame.txt (No such file or directory)
    at java.io.FileInputStream.open(Native Method)
    at java.io.FileInputStream.<init>(FileInputStream.java:138)
    at game.main(TheGame.java:512)

该文件确实存在.
