Scala io.Source.fromfile not finding my file even with absolute path specified

Question

I am trying to access a file in Scala using io.Source.fromfile.
I have specified the full path, but i am still getting a no such directory or file error.

This is a general version of what my code looks like:

val lines = io.Source.fromFile("~/top/next/source/resources/desiredFile.txt").getLines()

I'm running Ubuntu if that makes any difference.

It probably because you are using tilde sign, use full absolute path. If you want to avoid hard coding your home directory, you can get it from environment variables:

val home = System.getProperty("user.home")
val s = Source.fromFile(s"${home}/.....").getLines()

meaning what exactly? Should I specify home/ instead of ~/?

The compiler was assuming it should start in the project folder I was already in, so when I specified the directories above that folder, it tried to find them all as a sub-directory of my root project folder.
This would obviously cause an error.

I now have:

val lines = io.Source.fromFile("source/resources/desiredFile.txt")

which is working properly
