Rescans the plugin directory and refreshes the list of available plugins. Requires PLUGIN ADMIN permission.

Syntax​

SCAN PLUGINS;

Description​

SCAN PLUGINS walks the directory configured by cairo.plugin.root and registers any new .jar files it finds. It also removes stale entries for plugins that are no longer in the directory and are not currently loaded.

The scan runs automatically at server startup. Run it manually after copying a new plugin JAR into the plugin directory while the server is running. After scanning, use LOAD PLUGIN to activate the newly discovered plugin.

Already-loaded plugins are not affected by a rescan.

Example​

Discover and load a newly copied plugin
SCAN PLUGINS;
SHOW PLUGINS;
LOAD PLUGIN 'my-plugin-1.0.0';
