Problem

Integration with Bamboo stops working - i.e. triggers, creation of new branches - and the following appears in the atlassian-bitbucket.log:

Cause

The RemoteEvent class from the dev-summary-plugin was not loaded correctly during the last startup.

Resolution

  1. Shut Bitbucket Server down.
  2. Backup and remove the following directories. They will be rebuilt when Bitbucket Server starts again.
    1. $BITBUCKET_HOME/plugins/.bundled-plugins/
    2. $BITBUCKET_HOME/plugins/.osgi-cache/
  3. Restart Bitbucket Server.
