Error : Warning: Task "less" not found. Use --force to continue. about assemble-less

Sounds like the task isn't being loaded. Are you using something like load-grunt-tasks? If so, it will only load tasks with the name grunt, so you have to add it to the gruntfile. e.g

grunt.loadNpmTasks('assemble-less');

Ok, it's work ! :)
But now i have the following error with assemble-less : "Warning: An error occurred while processing a template (Cannot read property 'dest' of undefined). Use --force to continue" but not with grunt-contrib-less

It sounds like a lodash template issue. something in your config is defined wrong. Do a search for .dest in the gruntfile (and any config files that you have, e.g. grunt.file.readJSON('foo.json')), you might see the inconsistency.

If you can't find it, try using real filepaths for dest values, instead of config templates until you find which one is causing it. (e.g. do foo/bar/*.html instead of <%= foo.bar %>/*.html.
