I need to add a custom form (new, view and display forms) in a SharePoint Hosted app.  I did follow these two articles [article1][1]  and [article2][2].

Steps so far

 - Created a SharePoint App project
 - Added a custom list (Employee) to the app
 - Added a custom new form and set the deployment type of the aspx to element file
 - Added the following line in the list schema.xml file

    '<'Form Type="NewForm" Url="NewEmployee.aspx" Path="NewEmployee.aspx" WebPartZoneID="Main"Template="NewEmployee.aspx"/>'


 When I change the original form tag to the one shown above as suggested by the solution does not build and fails when I try to deploy it.

The error in the Output window is as below

  App installation encountered the following errors:
  05/04/2017 00:12:02
  
  

    @"Error 1
