WARNING: Tried to load angular more than once

[dejan7]

Only after i inject the 'directives.customvalidation.customValidationTypes to my app module, i get
"WARNING: Tried to load angular more than once" in console. I'm using gulp to load (concat) the files, this is the order:

return gulp.src([
    'source/js/*.js',
    'node_modules/angular/angular.min.js',
    'node_modules/angular-animate/angular-animate.min.js',
    'node_modules/ui-router/release/angular-ui-router.min.js',
    'node_modules/angular-ui-form-validation/dist/angular-ui-form-validation.js',
    'source/main.js',
    'source/routes.js',
    'source/services/*.js',
    'source/models/*.js',
    'source/controllers/*.js',
])

At the very top you see source/js/ folder being loaded, that's where jQuery is. Then i load angular, then i load ui-form-validation. I tried with both jQuery 1.11.3 and 2.1.4 and it's the same. Any ideas?
Thanks
