failOnError doesn't seem to work

[PAStheLoD]

Hello!

According to the docs, the process should be killed on failOnError: true, and with wait: true the task should be failed, but I don't see this happening. (Nor do I actually saw any code related to this in run.js.)

// from a Gruntfile.js
        run: {
            t: {
                options: { failOnError: true, wait: true },
                args: ['t.js']
            },

# t.js
console.log("this goes to stdout ");
console.error(" this goes to stderr ");

And there is output on stderr:

pas@strange:~/$ node t.js  1>/dev/null
 this goes to stderr 

Yet

pas@strange:~/$ grunt run:t
Running "run:t" (run) task
this goes to stdout 
 this goes to stderr 

Done, without errors.

Luckily exit-code checking works wonderfully with wait.

Could you look into this?
Thanks.

Indeed it doesn't work.
You can use grunt fail instead.

const grunt = require('grunt');
grunt.fail.warn('Error message');
