Duplicate plugin found (installed version is the same or older) and could not be unloaded: 'com.atlassian.jira.plugin.ext.subversion'

updated the subversion plugin in JIRA 5.2.5 and I am getting the following exception after system restart.

I reckon that the plugin may still exist in $JIRA_INSTALL/atlassian-jira/WEB-INF/lib directory; since versions before 0.10.12 is a version 1 plugin.

Try this:

1. Shutdown JIRA
2. Search for the old plugin inside the directory mentioned above, and delete it:
   • atlassian-subversion-plugin-*.jar
   • javasvn-*.jar (if any)
   • svnkit-*.jar (if any)
   • ganymed-*.jar (if any)
   • trilead-*.jar (if any)
3. Remove the subversion-jira-plugin.properties file from WEB-INF/classes.
4. Remove the plugin's index files by going to the plugins directory in JIRA's index directory. Then remove the atlassian-subversion-revisions directory.
5. Ensure that the new plugin resides in $JIRA_HOME/plugins/installed-plugins
6. Remove the following:
   • $JIRA_HOME/plugins/.osgi-plugins
   • $JIRA_HOME/plugins/.bundled-plugins
   • $JIRA_HOME/.jira-home.lock (if exists)
   • $JIRA_INSTALL/work
7. Start JIRA up.

Hope this helps!
