This is the default for Jenkins, if a command exits with a non-zero exit code, then the job should already fail.

By default, Jenkins runs "Execute Shell" steps with "/bin/sh -e -x". Due to "-e", the step will fail if any of its commands fail. And if the step fails, the build fails, too.

HTH...

The question is about Linux commands, not Groovy.

Hi,

below is my configuration:

    echo "welcome"
    echo ${var}      ( Note : I am not defined var)
    echo "hello"

expected output status: failure

output:

         

             + echo welcome 

                welcome 

             + echo 

              + echo hello 

                 hello 

              Finished: SUCCESS

`echo ${var}` didn't fail. As you can see, it printed an empty line. By default, bash allows references to undefined variables. Use `set -o nounset` to change this behavior.

This really isn't a Jenkins question, this is a question about shell use, and should be asked in the appropriate forum.

echo NEVER fails. If ${var} is not defined, echo will output an empty string, so you'll see an empty new line in your build's log.

If you want it to fail, you'd need to test whether the variable is defined, maybe like so:

[ -n ${var} ] || exit 1

See "man test" for the details.

Hi ,

The above one I am taking as example but actual configuration is:

                      < python_file> -D&1 2 | tee gen.file.log

above command   return "ValueError: No JSON object could be decoded"

but the job build status is showing success

Thanks

set -o pipefail.

You're still asking in the wrong forum.
