We have multiple batch jobs we use which have been configured using spring boot 1.2.0 and used with spring batch admin. We are now trying to convert these jobs to tasks so that we can implement them in spring cloud dataflow. For this, I update the spring boot from 1.2.0 to 1.3.2. I added the @EnableTask annotation after which it recognizes it as a task but when the batch job runs and i click the jobs tab on the UI, the scdf server gives an error saying "Spring batch application ran which wasn't a Task". For this, I also added the @EnableBatchProcessing to the main application. After which I am getting the following error:
org.springframework.beans.factory.BeanCreationException: Error
