Cannot run shell script from java Command Line

Question

I'm trying to run this script shell from java, but it's not working.

I get this error message:

Process exited with an error: 1 (Exit value: 1)

Can someone help?

String pwd = "blabla";

String s_key = "0000";

String path = "C:/Files/scripts"; 

CommandLine commandLine = CommandLine.parse("C:\\Program Files (x86)\\Git\\bin\\git.exe");

commandLine.addArgument("fileName.sh");

commandLine.addArgument(password);

commandLine.addArgument(s_key);

DefaultExecutor defaultExecutor = new DefaultExecutor();

ByteArrayOutputStream sdtout = new ByteArrayOutputStream();

ByteArrayOutputStream sdterr = new ByteArrayOutputStream();

PumpStreamHandler streamHandler = new PumpStreamHandler(sdtout, sdterr);

defaultExecutor.setStreamHandler(streamHandler);

defaultExecutor.execute(commandLine);

Here is the script

#!/bin/sh

pwd=$1
s_key=$2
....
echo $pwd

it works well with git bash

  $ ./fileName.sh blabla 0000

Have you tried inspecting the Exception or the stderr/stdout of the executor? commons.apache.org/proper/commons-exec/apidocs/org/apache/… — John Weldon

you said "works well with git bash", in order to execute the shell you need to open the Git Bash console ? o you can execute the shell directly on the Windows cmd console ? — reos

@reos yes i use git bash console, i've updated the question with console output. The script doesn't work on windows cmd console... thanks — Prosp

There are some points to be aware of.

If you want to run the git bash command you need to execute the git-bash.exe, on the cmd console you need to execute this command:

%windir%\system32\cmd.exe /c ""C:\Program Files\Git\git-bash.exe" --login -i -- D:\temp\test.sh param1"

If you want to execute it from a java app it's the same, the command you need to execute is git-bash.exe not git.exe. This is an example of running a command from java. I'm not using the objects that you're using but the simple java objects. However you can adapt it to your code.

 public static void main(String[] args) throws IOException {
          String[] command = {"C:\\\\Program Files\\\\Git\\\\git-bash.exe",
                  "D:\\temp\\test.sh",
                  "param1"};
          ProcessBuilder processBuilder = new ProcessBuilder(command);
          processBuilder.redirectErrorStream(true);
          processBuilder.start();
      }

the --login -i part might be important. So you should add it to your command. String[] command = {"C:\\\\Program Files\\\\Git\\\\git-bash.exe", "--login", "-i", "D:\\temp\\test.sh", "param1"};

There are a couple issues with your code:

You don't seem to be inspecting the stderr/stdout of the program, or inspecting the Exception that gets thrown.
Git.exe doesn't take shell scripts as the first argument. As @reos says, you probably need to invoke git-bash.exe rather than git.exe

thanks for your reply; i've updated the code with the stderr/stdout. now the error message is Process exited with an error: 1 (Exit value: 1). where should i put the file "fileName.sh" in the code?

Updated per reos' answer. Try invoking git-bash.exe rather than git.exe
