CI-Test

I did it!

Process

1. Designate a team bot in the yaml settings at Codecov. Either global or for the repository.

codecov:
  bot: olillin

2. Config GitHub Actions workflow with Gradle Build Action and Codecov actions. See the workflow file
3. Configure build.gradle to generate coverage reports using JaCoCo.
4. Run git update-index --chmod=+x gradlew to make gradlew runnable by GitHub Actions and avoid Error: Gradle script '/home/runner/**/gradlew' is not executable.
5. Get badge/shield from https://app.codecov.io/gh/olillin/CI-Test/settings/badge. Alternatively https://shields.io/category/coverage
