Thanks for this gist. When I run it in Circle CI 2.0, I get A client error (AccessDenied) occurred when calling the ListObjects operation: Access Denied. I tried running the same aws command locally with the same access key id and secret and it works. What did you have to do to get it to work in Circle CI? I set the following environment variables in the Circle CI web UI:

AWS_ACCESS_KEY_ID
AWS_DEFAULT_REGION
AWS_REGION
AWS_SECRET_ACCESS_KEY

Thanks!

I fixed it by replacing sudo apt-get -y -qq install awscli with this:

- run:
    name: Install AWS CLI
    command: |
      sudo apt-get update
      sudo apt-get install python-pip python-dev jq
      sudo pip install awscli

@monfresh thank you very much for sharing!

@monfresh nice comment. I needed to do the same steps with sudo pip install awscli as well to get around a seek error in my upload of coverage results.

upload failed: coverage/.resultset.json.lock to s3://virgent.codeclimate/coverage/1134/.resultset.json.lock seek() takes 2 positional arguments but 3 were given

Nice contribution @henrypoydar.

@monfresh @HoyaBoya i am having an error at this line - run: ./cc-test-reporter format-coverage --output "coverage/codeclimate.$CIRCLE_NODE_INDEX.json" at this line and it says Error: could not find any viable formatter. available formatters: clover, cobertura, coverage.py, excoveralls, gcov, gocov, jacoco, lcov, simplecov
