Grunt Jade Error

Whenever I run grunt jade I get an error: Warning: pattern.indexOf is not a function Use --force to continue. Now here is my jade task: jade: { options: {

Solution 1:

Your initial issues is that files should be an array of objects, not just an object: files: [{...}].

But then you have other troubles with your file definition:

• if you specify cwd, your src should not repeat it
• your ext needs a starting .
• your ! pattern needs to specify files instead of a dir

So you need:

files: [{
       expand:true,
       cwd: 'src/static/jade/',
       ext: ".html",
       src: ['**/*.jade', '!_includes/**/*.jade'],
       dest: 'build/'
}]
