How do I use a custom controller service in 2 sepa...

I have a custom controller service (nifi-cacheSinkService) created with the below structure:   ├── nifi-cacheSinkService │ ├── pom.xml │ └── src │ ├── main │ │ ├── java │ │ │ └── com │ │ │ └── sample │ │ │ └── cacheSinkService │ │ │ └── IgniteCacheService.java │ │ └── resources │ │ └── META-INF │ │ └── services │ │ └── org.apache.nifi.controller.ControllerService ├── nifi-cacheSinkService-api │ ├── pom.xml │ └── src │ └── main │ └── java │ └── com │ └── sample │ └── cacheSinkService │ └── LocalCacheService.java ├── nifi-cacheSinkService-api-nar │ ├── pom.xml ├── nifi-cacheSinkService-nar │ ├── pom.xml ├── pom.xml   I have pushed the `nifi-cacheSinkService-api-nar` and `nifi-cacheSinkService-nar` into lib folder of nifi. I have 2 custom processors created. One of them called nifi-transformMapper. ├── nifi-transformMapper-nar │ ├── pom.xml ├── nifi-transformMapper-processors │ ├── pom.xml │ ├── src │ │ ├── main │ │ │ ├── java │ │ │ │ └── com │ │ │ │ └── sample │ │ │ │ └── processors │ │ │ │ └── transformMapper │ │ │ │ └── TransformMapperProcessor.java │ │ │ └── resources │ │ │ └── META-INF │ │ │ └── services │ │ │ └── org.apache.nifi.processor.Processor ├── pom.xml The processors pom has this added in dependencies: <dependency> <groupId>com.sample</groupId> <artifactId>nifi-cacheSinkService-api</artifactId> <version>1.0-SNAPSHOT</version> </dependency> I have added a property that identifies the interface that extends my ControllerService : static final PropertyDescriptor CACHE_SINK = new PropertyDescriptor.Builder() .name("cache-sink") .displayName("Cache Service") .description("Specifies the Controller Service to use for performing cache tasks") .identifiesControllerService(LocalCacheService.class).required(true).build(); Now I place my nifi-transformMapper-nar file as well inside the lib folder. In nifi, I am able to create the controller service, but it doesn't allow me to choose that same controller service in my custom processor:   My objective is to use the same instance of the controller service in both the processors. ...
