    jsvalidate: {
      options:{
        globals: {},
        esprimaOptions: {},
        verbose: true
      },
      targetName:{
        files:{
          src:[
            '*.js',
          ]
        }
      }
    },

PhoneNumber.js is a folder, '*.js' match it, grunt-jsvalidate try to read it as a file.

Here is stdout:

➜  repo git:(master) ✗ grunt jsvalidate
Running "jsvalidate:all" (jsvalidate) task

Warning: Unable to read "PhoneNumber.js" file (Error code: EISDIR). Use --force to continue.

Aborted due to warnings.

Why do you need to name your folder with a file extension?
