To Reproduce Could reproduce it here: https://github.com/kroeder/gql-gen-custom-plugin-issue-repo Anything I got totally wrong?

It would help if the error message would show a full path instead just the filename

Expected behavior Script in my plugin would be executed

Environment:

• OS: Windows 10
• Codegen: ^0.14.0
• Node: ^10.12.10

@kroeder We recently changed the name of the enums values to math all other naming conventions.
