Yaml editor fails to validate substituted @[email protected]

In switching to spring-boot 1.3.0.RC1 I also had to update my application.yml file to use @[email protected] for Maven substituted values. The yaml editor however now marks my file as containing an error:

application.yml
{{
info:

1. Maven project properties
   project:
   groupId: @[email protected]
   artifactId: @[email protected]
   version: @[email protected]
   }}

error:
{{
found character @ '@' that cannot start any token. (Do not use @ for indentation) application.yml /my-api/src/main/resources
}}

What can be done to resolve this error?
