Unable to access jarfile

[DeaD_EyE]

I guess you're running your tool in a different directory and Python is searing at the wrong places.

import subprocess
from pathlib import Path


script_dir = Path(__file__).parent
jar_file = script_dir / "XYZ.jar"

subprocess.call(["echo", "Path", jar_file.absolute()])

Changed in version 3.6: args parameter accepts a path-like object if shell is False and a sequence containing path-like objects on POSIX.

Changed in version 3.8: args parameter accepts a path-like object if shell is False and a sequence containing bytes and path-like objects on Windows.

If your Program have to be stated inside the program directory, you can tell this subprocess to do.

# will print /var
subprocess.call(["pwd"], cwd="/var")
