Logback configuration reload.

Implementation notes:

Plugin hooks into ch.qos.logback.core.joran.GenericConfigurator.doConfigure(URL) call. All configuration URL’s are registered and watched for change. After the file change, full reconfiguration via the same method is executed.


  • The plugin registers directly to the file URL. This is usually target/classes/logback.xml. If used together with watchResources property in hotswap-agent.properties, the change may be only in src/main/resources/logback.xml and hence not triggered. Usually this is solved by IDE’s copy resources on save feature.
