A service can be converted to a light one

Reports services registered in plugin.xml that can be converted to light ones.

A service that is not intended for overriding is not required to be registered in the plugin.xml file. Instead, annotate the service class with the @com.intellij.openapi.components.Service annotation. For project-level services, specify @Service(Service.Level.PROJECT).

Requirements:

• IntelliJ Platform 2019.3 or newer.

• Service class must be final.

• serviceInterface is not specified.

• If the application-level service is a com.intellij.openapi.components.PersistentStateComponent, roaming must be disabled (roamingType = RoamingType.DISABLED).

• None of these attributes is specified: os, client, overrides, id, preload.

Also reports services registered in plugin.xml whose classes are already annotated with @Service.

See Services in IntelliJ Platform Plugin SDK docs for more details.
