Grunt files api created unwanted files

I have the following piece of code in my Gruntfile.js:

    less: {
        dist: {
            options: {
                paths: ['less/**/*.less'],
                cleancss: true,
                strictImports: true,
                strictUnits: true
            },
            expand: true,
            cwd: 'src',
            src: 'less/style.less',
            dest: 'tmp/less.css'
        }
    },

My goal is to parse all less files in /src/less/**/*.less (currently only style.less) to a css file in tmp/less.css. Instead the file tmp/less.css/less/style.less is created. I noticed similar behaviour for other grunt plugins, so I don't think this has anything to do with the less plugin itself. I know I don't have to use expand and cwd, but I'm trying to understand the Grunt files api for a more complex configuration. What am I doing wrong?

Typically you will only want to output one or two files (to reduce CSS requests) so it makes more sense for LESS to specify the compile targets explicitly. So a simpler setup similar to yours is probably preferable.

less: {
    dist: {
        files: {
            'src/tmp/less.css': 'src/less/style.less',
            'src/tmp/less2.css': 'src/less/style.less'
        },
        options: {
            cleancss: true,
            strictImports: true,
            strictUnits: true
        }
    }
},

Something like this should take all .less files in a less dir and output them with the same folder structure in a tmp dir:

less: {
    dist: {
        files: [{
            expand: true,
            cwd: 'src',
            src: ['less/**/*.less'],
            dest: 'tmp/',
            ext: '.css'
        }],
        options: {
            cleancss: true,
            strictImports: true,
            strictUnits: true
        },
    }
}
