Fatal error: Cannot read property 'files' of undefined #559

Since a year has passed without an answer, I create a new issue:

I use grunt watch with the following modules to minify the code in my website:

  • grunt-contrib-uglify
  • grunt-contrib-compass
  • grunt-contrib-htmlmin

Everytime I launch grunt watch and modify some file, i got this error:

Fatal error: Cannot read property 'files' of undefined

Even with grunt watch --verbose I don't get any other useful info than the error
If I launch the tasks separately (eg. grunt uglify) they work with no problems.

Here's the package.json:

module.exports = function(grunt) {

  // Project configuration.
  grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),
    htmlmin: {
      build: {
        options: {
          removeComments: true,
          collapseWhitespace: true,
          ignoreCustomFragments: [
            /\{\{[\s\S](.*?)\}\}/,
            /\{\%[\s\S](.*?)\%\}/,
            /<\?[\s\S]*?\?>/
          ]
        },
        files: [
          {
            expand: true,
            cwd: 'dev/html/layout',
            src: ['*.html'],
            dest: 'theme/layout',
            ext: '.liquid',
            extDot: 'last'
          },
          {
            expand: true,
            cwd: 'dev/html/snippets',
            src: ['*.html'],
            dest: 'theme/snippets',
            ext: '.liquid',
            extDot: 'last'
          },
          {
            expand: true,
            cwd: 'dev/html/templates',

    },

  });

  // Load the plugins that provides the tasks.
  grunt.loadNpmTasks('grunt-contrib-htmlmin');
  grunt.loadNpmTasks('grunt-contrib-uglify');
  grunt.loadNpmTasks('grunt-contrib-compass');
  grunt.loadNpmTasks('grunt-contrib-watch');

  // Default task(s).
  grunt.registerTask('default', ['watch']);
  grunt.registerTask('build', ['compass','uglify','htmlmin']);
};

Here's the environment I'm working with:
