Launch specific external process in Scala - scala

Question

I've been struggling to launch a specific external process in Scala. It works for most programs, but when I try
Array("gnome-terminal", "--working-directory",
"/mydir", "-x", "bash", "-c", "tmux attach")
it fails. I tried the same using Python's subprocess.Popen and it worked perfectly. Any suggestion?
My code is:
object Test {
def main(args: Array[String]):Unit = {
val source = Source.fromFile("file.txt")
val lines = source.getLines
lines.toList.map(raw => {
val programAndOptions = raw.split('$')
// here I get the Array mentioned above
Process(programAndOptions) run
})
source.close
}
}
Update
My file.txt is something like this:
evince$/path/to/my/pdf
evince$/path/to/other/pdf
nautilus$/path/to/my/working/directory
gnome-terminal$--working-directory$/mydir$-x$bash$-c$tmux attach
Update2
I ran the same code again to test and try some other things and it worked 'as is'.

'Run' is non blocking so it execute the program and continue with the code, which is this case is source.close and exit. Exiting the jvm probably kill the app.
Try using the '!' function instead of 'run' or do something like:
val p = Process(programAndOptions) run
p.exitValue
