Using Jenkins

Hey,
I have a problem:
When I create a project and click on “Build” and select Execute shell and build the project -
I got an error in the console output

There is a syntax error in your shell script. The first line that you show has a space character in it that is unexpected.

Instead of:

#! /bin/bash -ex

you want

#!/bin/bash -ex
