Talking with the Gradle team, it was discovered that a build scan won't be created for the underlying build, as we do using the IncludeCheckRemote plugin.
We should consider using Gradle's Composite Build to be able to get more detail about the sample's build.

Playing with this, I saw that the task was being over-engineered, we don't really need Composite Builds for this, just cloning the repository and running ./gradlew --project-dir /project-directory :task should be enough
