FileUtil.createMissingParentDirectories always returns false

[renegat59]

Hi,
I am using LogBack in the company I work for and we encountered an issue with it. The problem is that in line 58 of FileUtil there is a call to parent.exists(), but that returns false if the path is relative. I didn't arrive to the source of the problem, I was trying to set -Duser.dir as is suggested here but it doesn't help. However I see that something like this works:

parent.getAbsoluteFile().exists();

in the image you can see the variables from my debugger:

As you can see the user.dir is correct but still the exists() on relative file is failing.

What do you think about changing that to use getAbsoluteFile()? Do you see anything against? Or maybe you have an idea how to fix it on our side? I'm happy to make this change and prepare PR if needed.

Can you specify the OS, JDK version where this issue occurs?

A test case would be most appreciated. The test case can omit using logback, and involve only the File.exists() method.

@ceki thanks for your answer. I did more tests and I realized that it was Gradle messing around with me. We have multiple modules inside one repo and running gradle from the root of the repo. Some commands had different cwd (of the module) and that's why it was failing. I managed to fix it on our end.
Thanks again!
