      Description

      Problem Definition

      Often, on startup or on Add-on update Confluence has errors with Add-Ons that have versions that clash with each other. This often causes issues for customers and support tickets.

      Please also see related bug

      In atlassian-confluence.log we can see errors like

      2017-07-22 21:28:39,769 WARN [localhost-startStop-1] [osgi.container.felix.FelixOsgiContainerManager] doLog Unable to resolve bundle 226: Unresolved constraint in bundle net.customware.confluence.plugin.scaffolding [226]: Unable to resolve 226.0: missing requirement [226.0] package; (&(package=org.randombits.confluence.metadata)(version>=7.4.1)(!(version>=8.0.0))) [caused by: Unable to resolve 229.0: missing requirement [229.0] package; (&(package=org.randombits.supplier.core.annotate)(version>=1.0.9)(!(version>=1.1.0)))]
      

      Another example is when running version 4 of ScriptRunner and upgrading to version 5.

      Only clearing the plugin cache does not always resolve this issue.

      Suggested Solution

      Have better version checks in the plugin loader for incompatible versions.

      Workaround

      This is documented here for the ScriptRunner issue

      For other plugins, remove the plugin from the database directly

      1. Shutdown Confluence
      2. Check the logs and query the database to determine the correct plugin to remove
        select plugindataid, pluginkey, filename, lastmoddate from plugindata;
        
      3. Remove the plugin from the database
        delete from plugindata where pluginkey = '<pluginkey>';
        
      4. Update bandana table (if required)
        update bandana set bandanavalue = '<map/>' where bandanakey = 'plugin.manager.state.Map';
        
      5. Clear the plugin cache
      6. Restart Confluence
