Bitbucket pipeline - possibility to merge one branch to another

[Konrad Bal]

I have a repository with two branches: master and DEV and I want to configure that pipline in such a way that when I push code to dev branch and code build was successfull, the DEV was merged to master. Unfortunatly I can't find any information about merge in bitbucket piplines docs.

That's my yml file:

pipelines:
  branches:
    Dev:
      - step:
          script:
            - ant deployCodeCheckOnly -Dsf.username=$SF_USERNAME -Dsf.password=$SF_PASSWORD
