Hello, I’ve been having some difficulty trying to add a reference to the AWSCredentialsProviderControllerService in my code. Essentially I can add it as a property to my controller, all compiles fine and I can deploy and start Nifi. But then when I go to add reference to it in the Controller Settings, it says: "No controller service types found that are applicable for this property."
In case this was something strange in my code, I tried to revert to a more simple example. If download the code discussed in the tutorial at http://www.nifi.rocks/developing-a-custom-apache-nifi-controller-service/ I add this to StandardPropertiesFileService: public static final PropertyDescriptor AWS_CRED_SERVICE = new PropertyDescriptor.Builder() .name("AWS Credentials Service") .description("The credentials provider service") .required(true) .identifiesControllerService(AWSCredentialsProviderControllerService.class) .build(); and of course add the property in the static initializer: props.add(AWS_CRED_SERVICE); and add the only available dependencies for aws at sample-controller-service-api/pom.xml: <dependency> <groupId>org.apache.nifi</groupId> <artifactId>nifi-aws-nar</artifactId> <version>${nifi.version}</version> <type>nar</type> </dependency> <dependency> <groupId>org.apache.nifi</groupId> <artifactId>nifi-aws-processors</artifactId> <version>${nifi.version}</version> </dependency> if I build with tests I get ControllerServiceProcessorTest.testOnTrigger:65 Processor has 1 validation failures: 'Properties Service' validated against 'propertiesServiceTest' is invalid because Controller Service is not valid: 'AWS Credentials Service' is invalid because AWS Credentials Service is required If I build with skipTests and deploy I will get the "No controller service types found that are applicable for this property." I notice that the AWS bundle doesn't split itself out into an API and implementation like the pattern discussed in the tutorial and the way it seems the other NIFI services are done. Is that an issue? Any help appreciated, Thanks, Tim
