原因
As announced in Confluence 7.11 Release Notes, Team Calendars for Confluence became a built-in feature for Confluence Data Center releases. Previous to this, it was needed to install Team Calendars as non-bundled plugin following the steps outlined in Install Team Calendars
If you installed Team Calendars in versions prior to Confluence 7.11, you will have a entry in the PLUGINDATA table that refers to the old JAR library file used by the Team Calendars non-bundled plugin. This entry may look like this:
SELECT plugindataid, pluginkey, filename, lastmoddate
FROM plugindata
WHERE pluginkey='com.atlassian.confluence.extra.team-calendars';
Additionally, in the Confluence startup logs, you may notice that Team Calendars plugins is marked as installed on a specific date in the "Enabled Plugins" section:
--------------------------
Enabled Plugins
--------------------------
...
...
Team Calendars (com.atlassian.confluence.extra.team-calendars, Version: 8.0.7, Installed: Jun 22, 2023)
...
...While the expected entry should explicitly specify that this plugin is "bundled":
Team Calendars (com.atlassian.confluence.extra.team-calendars, Version: 8.0.7, Installed: bundled)ソリューション
In order to get ride of this error message, just follow these steps:
- Stop Confluence
Delete the entry in the PLUGINDATA table regarding the non-bundled plugin:
DELETE FROM plugindata WHERE pluginkey='com.atlassian.confluence.extra.team-calendars'- Start Confluence again
Removing the plugin entry from the database this way won't delete the information associated with them. It will just stop Confluence from loading them.
This means if you choose to re-install a plugin, the data it contains will still be present in the database (as that information is stored elsewhere).
