Diagnosis
When doing a directory listing of ls -la in <Confluence Home and other important directories>/plugins-osgi-cache/felix you can see that the jar files in this directory are owned by different users. A typical scenario is they are owned by root and 'confluence' users.
Cause
Confluence is not able to load/delete some of the plugin jar files in the <confluence home>/plugins-osgi-cache/felix folder because of permission issue.
Solution
Resolution
Remove the
<confluence home>/plugins-osgi-cache/felixfolderYou may need to How to clear the apps (plugins) cache in Confluence Data Center, not just the
<confluence home>/plugins-osgi-cache/felix
Depending on the OS, perform the following:
For Linux: Restart Confluence as a 'confluence' user. Which is a non-root user created by your system admin to start Confluence.
For Windows: Right click on
<Confluence_Home>and hit Properties. Navigate to the Security Tab and make sure that the user running Confluence has Full Control of this folder. Then startup Confluence again
