Hi,
I am trying to run your project on my machine but I get the following errors:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.5.1:compile (default-compile) on project kafka-streams-stockstats: Compilation failure: Compilation

If you could just help me resolve these errors it will help me out to move ahead. Thank you!
