Diagnostic Steps

• Check atlassian-jira.log to verify that the add-on specific to Trello is not disabled during started.
• Check from Manage add-on page whether there is any disabled add-on.

• Run the following query to check from database to find any disabled plugin which is related to JIM or Trello:

  SELECT * FROM pluginstate where pluginenabled = 'false';

• The following may appear in the atlassian-jira.log

原因

These are the potential causes:

1. Add-on responsible for Trello export is disabled.
2. If you are using a Jira version between 8.4 and 8.17, this is due to the fact that Trello Importer is decommissioned starting from 8.4 as part of End of support announcements.
3. If you are using a Jira version equals to or later than 8.17.0, then this functionality will not show in your system since it was completely removed starting from Jira 8.17.

ソリューション

原因 1

          Resolution 1:

• Open your Manage add-on page and list all add-on from the add-on option. By default, JIRA only displays user add-ons.
• Look for any plugin which contains "Trello" in its name.
• Enable it and try to open your External System Import.

• If this does not work, please follow the steps below:

• Resolution 2:
  
  

• Stop your JIRA.
• Run the SELECT * FROM pluginstate where pluginenabled = 'false'; query in your JIRA's database.
• Execute the DELETE from pluginstate WHERE pluginkey='<pluginkey of trello plugin from query above>'; query by replacing parameter in "'<pluginkey of trello plugin from query above>".
• Restart your JIRA and verify whether Trello option is available in External System Import.

原因 2

You may bring back the functionality by enabling the following dark features:

• jim.feature.show.deprecated.importers
• jim.feature.show.unavailable.importers

That said, please note that this external importer is no longer supported in your current Jira version so Atlassian Support might not be able to help much in case you run through issues.

原因 3

The functionality was completely removed and enabling the dark features from the resolution for cause 2 will have no effect. In this case, you still can use the JSON export in Trello and import the JSON file in Jira.
