I'm trying creating a task to check my js, but every time I call the function it fails:

my code (just stripped it down to the essentials):

var gulp = require('gulp');
var jscs = require('gulp-jscs');

gulp.task('lintjs', function(){
  gulp.src(['./app/js/**/*.js','./.tmp/js/**/*.js','./gulpfile.js','./tools/**/*.js'])
    .pipe(jscs())
    .pipe(jscs.reporter())
});

the error:

[11:25:13] Starting 'lintjs'...
[11:25:14] 'lintjs' errored after 305 ms
[11:25:14] TypeError: Cannot convert undefined or null to object

apparently a .jscsrc file is required. Maybe write that down in your docs, it's obligatory to create such a file? With a .jscsrc file I don't get any errors.

Hey @mike-lighthouse,
I have exactly the same issue it doesn't seems working even with the .jscsrc file.
Where did you put your file?

radek11 commented

put the .jscsrc file where the gulpfile.js is (or I think where gulp can find it)
