How can we redirect a Java program console output to multiple files?

Question

How can we redirect the eclipse console output to a file? I can:

1. Run Configuration->Commons->Select a file.
2. Use System.setOut(PrintStream) and System.setErr(PrintStream).

The problem with 1) is that I need to record console output to different files instead of one file.

The problem with 2) is that it only stores console output generated by System.out.println() or stacktrace of an exception thrown. It does not capture other kind of outputs e.g. log4j warnings etc.

How can we redirect console output to different files programmatically?

Answer 1

Go to run as and choose Run Configurations -> Common and in the Standard Input and Output you can choose a File also.
