How to run bash script from Java

Question

I've seen many similar posts but I am still stumped. I want to run this shell script with a Java program :

C:\\Users\\pro-services\\Desktop\\projects\\github\\cygwin\\TEST.sh

Here's what the code looks like:

ProcessBuilder pb = new ProcessBuilder("C:\\Users\\pro-services\\Desktop\\projects\\github\\cygwin\\TEST.sh");
Process p = pb.start();

I am trying to use Process Builder but I'm not sure how to get it to work - I keep getting the error:

Cannot run program "C:\Users\pro-services\Desktop\projects\github\cygwin\TEST.sh": CreateProcess error=193, %1 is not a valid Win32 application

I know there are other fields of ProcessBuilder that I'm not using. I also know that there may be syntax issues here. I wrote my script for Cygwin. Any help please?

Instead of passing the script as an executable to ProcessBuilder, pass in the path to bash binary and pass your script as argument:

ProcessBuilder pb = new ProcessBuilder("C:\\path\\to\\bash.exe", "C:\\Users\\pro-services\\Desktop\\projects\\github\\cygwin\\TEST.sh");
Process p = pb.start();
