Problem Definition

Since User and Group management is handled by REST APIs since Bamboo 6.2, for external groups whose names include "special" characters for URLs, such as # and ?, the functionality fails to add the groups because the REST URL stops reading at those characters

Suggested Solution

Encode the Group (and User) calls to use the URL encoding for these characters.

Why this is important

Some companies have corporate group naming schemes that require these characters.

Workaround

Use cURL to send a REST API call
Example: Adding a group called #testgroup with all Administration privileges:

curl -XPUT \
-H'Content-Type: application/json' \
-u<user>:<pass> 'http://<bamboo-url>/rest/api/latest/permissions/global/groups/%23testgroup' \
-d '["ADMINISTRATION","CREATE","CREATEREPOSITORY","READ"]'
