診断
Notice the message in the error: Multiple entries with same key: SOFP=10000 and SOFp=10000It shows the project keys (SOFP and SOFp) and the project ID (10000)
The issue described here happens when the project keys differ only in the character case. In this example, the last character.
原因
Jira allows changing the project key, as documented in Changing the project key format.
When loading the project keys from the project_key table into the cache, there are entries that differ only in case. In the example, "SOFP" and "SOFp".
If we allow lower case characters and at some point change only the case in the project key, Jira understands that the entries in the project_key table are duplicates, causing these errors.
ソリューション
- Notice the message in the error:
Multiple entries with same key: SOFP=10000 and SOFp=10000It shows the project keys (SOFPandSOFp) and the project ID (10000) - Find the entries in the database:
SELECT * FROM project_key WHERE project_ID=10000例:
| ID | project_id | project_key |
|---|---|---|
| 10200 | 10000 | SOFP |
| 10000 | 10000 | SOFp |
- Choose the one to be removed and remove it. Following the example above:
DELETE FROM project_key WHERE id=10000;
COMMIT;
Make sure to always have a backup before making database changes.
- Shutdown all the nodes.
- Start Jira again.
