Using repo pattern with asterisk for application causes YML error

[jogjayr]

Steps to

1. Clone spring-cloud-config
2. Modify spring-cloud-config-server's application.yml with the configuration given in the documentation:

spring: cloud: config: server: git: uri: https://github.com/spring-cloud-samples/config-repo repos: development: pattern: - */development - */staging uri: https://github.com/development/config-repo staging: pattern: - */qa - */production uri: https://github.com/staging/config-repo

(Note: Github has mangled my copy-paste, stripping out all newlines and whitespace. You can find the config here: http://cloud.spring.io/spring-cloud-config/spring-cloud-config.html#_pattern_matching_and_multiple_repositories)

3. Start the server

Expected:

Server starts without issues

Actual:

• Server does not start

Note: Github has also mangled my stack trace a bit, or I couldn't figure out how to format it correctly. My apologies.

[spencergibb]

You need to surround the item with single quotes. This is a yaml requirement.

[jogjayr]

@spencergibb maybe the documentation and example needs to be updated then? Can this issue stay open to track that? My particular test case is a direct copy-paste from the documentation so it should work as-is.
