Eclipse中的I / O重定向？ [英] I/O redirection in Eclipse?

问题描述

可以在Eclipse中使用I / O重定向吗？

Is it possible to use I/O redirection in Eclipse?

我想在命令行上重定向标准输入/输出，如 java MyProgram< input.txt> output.txt ，但我似乎无法让它在Eclipse中工作。我尝试将<'作为程序参数的一部分，这被忽略，并且在VM参数中，它只是抛出一个未找到的类错误。如何做到这一点？

I want to redirect standard input/output on the command line like java MyProgram <input.txt >output.txt, but I can't seem to get it to work in Eclipse. I tried including the <'s as part of the program arguments, which was ignored, and also in the VM arguments, which just threw up a class not found error. How can I do this?

推荐答案

为了真正重定向两者，最简单的方法是将程序定义为外部脚本

To truly redirect both, the simplest way is still to define your program as an external script

 "java %1 %2 %3 %4 < %5 > %6"

（适应您的特定程序的参数数量）

(adapt the number of parameters to your particular program)

在运行菜单中，单击外部工具... /打开外部工具对话框，并定义外部启动配置，您将在其中指定参数和输入和输出文件。

In the Run menu, click 'External Tools.../Open External Tools Dialog" and define an external launch configuration in which you will specify both the arguments and the input and output file.

这不是一个理想的解决方案，因为您无法直接调试您的代码（使用调试启动器配置）。

相反，您必须远程调试（在您的通用Java启动器中添加' -Xdebug -Xrunjdwp：transport = dt_socket，server = y，suspend = n，address = 8000 '脚本）

It is not an ideal solution though, as you cannot debug directly your code (with a "debug" launcher configuration).
Instead you have to remote debug it (add '-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000' in your generic Java launcher script)

启动外部工具后，通过调试启动器Remote J启动远程调试会话ava应用程序部分：

Once you have launched your external tool, launch a remote debug session through the "debug launcher 'Remote Java Application'" section:
