症状

JIRA is unable to find any user on trying to change project roles ( _Administration > Project Administration > Project Roles > People Tab). The user picker always says No Matches

原因

This is occurring because the tag jira.ajax.autocomplete.userpicker.limit has a small number than the amount of existing users in the instance.

ソリューション

1. Check how many users are present in the instance. The following SQL command could be helpful 

   
   

   1. For JIRA 4.4.x or later (this setting is not present after 5.x)

      select count(*) from cwd_user

2. As outlined in Advanced JIRA Configuration, open the file JIRA_HOME/jira-config.properties to change the related tag value. If it doesn't exist, please create a new one.
3. Set the related tag to a value greater than the number of existing users.
