Compile less files with grunt-contrib-less won't work

Question

I\'m using Grunt for building my web project. I installed grunt-contrib-less package und added a task to my grunt.initConfig({..});

Answer 1

The glob pattern js/base/*.css does not match any files, therefore there is no destination. Usually, tasks like this expect multiple inputs to combine into a single output. Also, bear in mind that less is a multi-task, and putting files as a child of less is not doing what you expect. (it is treating it as a target, not a src/dest map)

If you want a 1-1 transform of .less into .css, you can use dynamic expansion. (or you can define each src/dest pair manually, but who wants to do that?)

In your case:

less: {
    options: {
        paths: ['js/base']
    },
    // target name
    src: {
        // no need for files, the config below should work
        expand: true,
        cwd:    "js/base",
        src:    "*.less",
        ext:    ".css"
    }
}
