The Update Center is the place for keeping the Sonar platform up to date. It allows to:

• List already installed plugins
• Check and install plugin updates
• List available plugins and install new ones
• Check Sonar platform updates

To take effect, most actions taken in the Update Center (updating a plugin...) will require Sonar to be restarted. The Update Center is only accessible to administrator: Settings > System > Update Center.

Installed Plugins

This tab displays the list of installed plugins and the list of system plugins. System plugins are the one that are built in Sonar core. They cannot be updated nor uninstalled. Non-system plugins can be uninstalled by clicking on the 'Uninstall' button:

Available Plugins

This tab displays available plugins for your Sonar version. They are grouped by category such as 'Additional Languages', 'Visualization/Reporting', etc. and can be installed by a simple click on 'Install':

Plugins Updates

This tab shows new versions of installed plugins. When an update is available, it can be installed by a simple click on 'Upgrade to...':

System Updates

This tab shows new version available for Sonar and path to migration in terms of plugins update (plugins need to be upgraded, uninstalled, etc.) to the new version of Sonar. Installation of the new Sonar version is manual.

Pending Operations

When taking an action in the update center (installing, updating or uninstalling a plugin), a yellow area appears on each tab. The area contains pending operations that will be executed when restarting Sonar. Pending operations can be canceled until Sonar is restarted:

Using the Update Center behind a Proxy

Update Center uses HTTP connection to external servers to provide these services. If Sonar is located behind a proxy, additional information must be provided in the 'sonar.properties' configuration file:

http.proxyHost=<your.proxy.host>
http.proxyPort=<yout.proxy.port>
