Symptoms

Uninstalling a plugin, from the plugin repository, will fail with a window pop-up such as "Could not delete plugin [KB:Plugin Name]." The following appears in the atlassian-confluence.log:

com.atlassian.plugin.PluginException: Could not delete plugin [Attachment Checkout Plugin].
	at com.atlassian.plugin.loaders.ClassLoadingPluginLoader.removePlugin(ClassLoadingPluginLoader.java:171)
	at com.atlassian.confluence.plugin.DatabaseClassLoadingPluginLoader.removePlugin(DatabaseClassLoadingPluginLoader.java:114)

	at java.lang.reflect.Method.invoke(Unknown Source)

When installing the outdated plugin, the log file shows:

Cause

The plugin is outdated or incompatible with the version of Confluence.

Resolution

Always backup your data before performing any modifications to the database.

  1. Find the Plugin's pluginkey from Administration >> Plugins >> (Select the Plugin). The pluginKey is displayed in the URL.

  2. Run the following SQL statement in your database:

    select plugindataid, pluginkey,filename,lastmoddate from plugindata;

  3. After you have found the plugindataid for the offending plugin, run the following:

    delete from plugindata where plugindataid='XXXXXX';

    where XXXXXX is the plugindataid value.

  4. Restart Confluence after performing the database update.
  5. In addition, you might need to go to <confluence-home>/plugin-cache and remove the offending plugin. You can clear the entire plugin cache directory safely; it will rebuild.
