No exercise files under staging/08-creating-a-source

[ksenia0822]

I am trying to follow instructions in https://developer.confluent.io/courses/flink-java/creating-a-flink-data-source-exercise/ and I do not see any exercise under staging/08-creating-a-source. Is that expected? For example, instructions say:

The first step is to create a consumer configuration to read from Kafka. The simplest way to do this is to copy from the producer.properties.

Create a new file: src/main/resources/consumer.properties.
Copy the configuration from src/main/resources/producer.properties.

However, there is no src/main/resources/producer.properties.

What am I missing?
