Overview
These are some generic tips and techniques to help resolve plugin installation or licensing problems. In many cases, installation problems are not specific to the plugin, but instead relate to general usage or issues with the Atlassian Universal Plugin Manager (UPM) or the underlying plugin system. Generally speaking, most recent versions of plugins on this site are built using Atlassian's plugin 2 framework and all paid plugins use Atlassian licensing support. Installation is provided by UPM. Licensing support is also provided by UPM except for older versions of UPM. If these tips don't resolve your issue, it is likely you will need to open an Atlassian support ticket.

Previously, most plugins shipped as jar files. Now it seems many are obr files. What is the difference and what do I need to know about this?
- An obr is an OSGi Bundle Repository. In simple terms, it contains the normal plugin jar file plus jar files for component plugins that are required
- It is installed via UPM the same as a jar file
- Most Bob Swift Software Confluence plugins contain a number of component plugins that are required for the plugin to work
- The UPM manages the installation of all the required plugins provided they are not already installed at minimum level required by the using plugin
- When installed, these component plugins show up in UPM like other plugins
- While these component plugins can be updated independently, normally plugin administrators should just worry about installing the primary plugin
- Plugin administrators should not disable these component plugins as will cause the using plugin to be disabled or not work as expected
What are these RB plugins?
For Confluence, Bob Swift Software takes advantage of some base enablers provided by a set of RB (formerly randombits) components supported by ServiceRocket. When a plugin gets installed, the RB components also get installed. Think of them as necessary plumbing. Generally, you should not have to worry about them. Never downgrade them!
Current, the following RB components are needed by most Bob Swift Software Confluence plugins.
