Ant profile deployment - You cannot deploy to a required field Object_Name__c.Field_Name__c

Question

I am getting the below error when I am trying to deploy a new profile:

You cannot deploy to a required field Object_Name__c.Field_Name__c.

I saw the solution posted here: Force.com IDE profile deployment - You cannot deploy to a required field Object_Name__c.Field_Name__c

But I have used an existing .profile file and I am trying to give read only access to all the fields and objects for an app.

There are a lot of objects and fields and hence not able to detect the required fields and remove them from the file.

Any solution for this? Any help is greatly appreciated.

Answer 1

"Since API version 30.0 a change set or ant deployment will fail if a field that is required in the field definition is included in a profile or permission set that is being deployed.

If you create a new custom field and check 'Required', Field Level Security automatically becomes 'Visible' for all profiles. Similarly, if you edit the definition of a custom field which is not visible to all profiles and check 'Required' then it automatically becomes visible to all profiles. Therefore there is no need to reference it in a permission set. Try it!"

It means, that you need to remove from profile metadata fieldPermissions of this field.
