I'm trying to use chisel 3.
I tried to test GCD.scala file in the chisel project template repo using sbt test and sbt "test-only example.GCD" commands following the answer to a previous question. But this gives an error(s) that I cannot find the reason for. I didn't do any changes to the build.sbt file or repo layout. I'm posting only the last part of the error message since it is very long and repetitive.

The errors you have shown suggest that sbt is somehow not finding Chisel, could you by chance show the full list of errors (especially early on ones)? With the following sequence of commands I am unable to reproduce the errors you are seeing:
git clone git@github.com:ucb-bar/chisel-template.git
cd chisel-template
sbt test
It is not the cause of this issue, but to run the test in chisel-template you should actually run sbt "test-only examples.test.GCDTester". example.GCD is the top of the design, but to run the test you have to refer to the Tester class in src/test/scala/examples/test/GCDUnitTest.scala.
