How to configure eslint with VS2017 to have errors and warnings into the "Error List" window

Question

I want to use eslint with VS2017 and follow these instructions :

• config
• eslint

ESlint seems to works when I call it from the "Task Runner Explorer" VS2017 Window via Gulp (see below), but I want have warnings and errors into the "Error List" VS2017 Window.

How do this ?

I've undertood that this was normally set by default, why i'm quite embarrassed.

My Gulp code :

gulp.task('eslint', function (done) {
gulp.src([
    paths.root + 'js/**/*.js',
    paths.root + 'Modules/**/js/*.js',
    '!' + paths.root + 'js/plugins/**/*.js',
    '!' + paths.root + 'js/lib/**/*.js'
])
    .pipe(eslint('./.eslintrc.json'))
    .pipe(eslint.result(function (result) {
        if (result.warningCount > 0 || result.errorCount > 0) {
            console.log('ESLint error: ' + result.filePath + ' : ');
            console.log(result.messages);
        }
    }))
    .pipe(eslint.failOnError())
    .on('end', done)
 });

What I get from the task runner explorer window :

ESLint error: [FILEPATH] :
[ { ruleId: 'no-unused-vars',
severity: 2,
message: '\'file\' is defined but never used.',
line: 54,
column: 32,
nodeType: 'Identifier',
source: '        removedfile: function (file) {' } ]
Process terminated with code 0.

Thank you for the help.
