Sbt cannot synchronize the project because it cannot be compiled

Question

I am quite at the beginner level so I would gladly accept some help to solve this problem...

I am using IntelliJ IDEA 2018.2.5 Sbt version: 1.2.6 JDK version: 1.8.0_191-b12 Scala is used as IntelliJ plugin (the most recent).

When I load the sbt project downloaded from coursera webpage with InteliJ the project is not synchronizing and I see lots of error messages. Also in build.sbt lines are red. I have copied the error messages and the lines of the build.sbt.

Here are the error messages. The list is not complete because of the max limit of links:
