Answer 1

You need to have spring-boot-configuration-processor, e.g.,

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-configuration-processor</artifactId>
</dependency>

Also, if you are using SCDF 2.6 or above, dataflow-configuration-metadata-whitelist.properties is deprecated in favor of dataflow-configuration-metadata.properties.
