title: AWS S3 Gitpull from Bitbucket and CodePipeline
body: <p>I'm setting a continuous delivery system using Bitbucket, Jenkins, and AWS Elastic Beanstalk.  </p>
  
  <p>I've got an issue where it appears the Bitbucket integration I've setup following this <a href="https://aws.amazon.com/blogs/devops/integrating-git-with-aws-codepipeline/" rel="nofollow noreferrer">article</a> is only building the master branch.  Without direct support in Code Pipeline, like Github and AWS CodeCommit, I'm not sure how to setup builds with specific branches such as develop or release candidate branches.  </p>
  
  <p>Is it possible to indicate which branch should be built in CodePipeline from an S3 zip of the repository?</p>
