[error/question/help] Running mailgun taks from a taks folder.

[marocas]

Hello, im getting this error after i separated my tasks from gruntfile.js to a folder _tasks, ATM im using grunt-load-configs and grunt-load-tasks on my project.
Since i made this change, mailgun stopped working.

// _tasks/mailgun.js
module.exports = {
  mailer: {
    options: {
      key: '<%= cfg.email.key %>',
      sender: '<%= cfg.email.sender %>',
      recipient: '<%= cfg.email.recipient %>',
      subject: '<%= cfg.email.subject %>'
    },
    src: ['html/email.html)] 
// it send the email test but the task never stop running,  i have to cancel it with ctrl+c. 

    src: ['<%= cfg.dist %>'+grunt.option('template')] 
// cmd line : grunt send --template=email.html, i use this method to send test email.
and i get the error below.
  }
};

If i change my module.exports like this to correct the missing grunt call:

// _tasks/mailgun.js
module.exports = function(grunt) {
  mailer: {
    options: {
      key: '<%= cfg.email.key %>',
      sender: '<%= cfg.email.sender %>',
      recipient: '<%= cfg.email.recipient %>',
      subject: '<%= cfg.email.subject %>'
    },
    src: ['<%= cfg.dist %>'+grunt.option('template')]
 // cmd line : grunt send --template=email.html
  }
}; 

i get this error:

Loading _workflow/_tasks/mailgun.js...Loading "Gruntfile.js" tasks...ERROR
>> C:\sites\bymailer\_workflow\_tasks\mailgun.js:5
>>       sender : '<%= cfg.email.sender %>',
>>                 ^

My taks worked fine on Gruntfile.js like this:

// gruntfile.js
'use strict';

module.exports = function(grunt) {

  var globalConfig = {
    cfg: globalConfig,
    email: {
      key:        'key-xpto',
      sender:     '[email protected]',
      recipient:  '[email protected]', 
    },
  };

  grunt.initConfig({

      cfg: globalConfig,
      pkg: grunt.file.readJSON('package.json'),

      // Use Mailgun option if you want to email the design to your inbox or to something like Litmus
      mailgun: {
        mailer: {
          options: {
            key:        '<%= cfg.email.key %>',         // Enter your Mailgun API key here
            sender:     '<%= cfg.email.sender %>',      // Change this
            recipient:  '<%= cfg.email.recipient %>',   // Change this
            subject:    '<%= cfg.email.subject %>'      // Change this
          },
          src: ['html/'+grunt.option('template')]
        }
      },

  });

  grunt.registerTask('send', ['mailgun']);
};

I must be missing something here, can you help me?

Best regards.
