Process not exited with code 1

// To have the process exit with an error code (1) on
// lint error, return the stream and pipe to failAfterError last.

It's not working, I have a task

gulp.task('checkJS', function (){
    return gulp
        .src(['src/app/**/*.js', '!**/*tests.js'])
        .pipe(plugins.eslint())
        .pipe(plugins.eslint.format('table'))
        .pipe(plugins.eslint.failAfterError());
});

But in TeamCity process not exited with code 1
