Bamboo throws file not found exception Java nio (file is present in central sharepath)

[RDF WnL]

I have a code to read the sharepath text file  and write some content to it after my tests finish.. my  local code(windows) Java nio- works in fine in sts without any issues .. but when I pushed the code to bamboo. It says no such file found exception even though the path and file both are correct and present . I check for spaces etc... Everything still same issue .
