After a git clone build with gradle 5.6.3 fails:

$ gradle clean :BigQueryWorkloadTester:build
> Task :BigQueryWorkloadTester:compileJava FAILED

FAILURE: Build failed with an exception.

The problem:

            > Could not HEAD 'http://repo.maven.apache.org/maven2/com/google/auto/value/auto-value/1.6.3/auto-value-1.6.3.pom'. Received status code 501 from server: HTTPS Required

Once this is resolved by changing the URL scheme for repo.maven.apache.org to https, the build fails with an error related to AutoValue:
