AutoMerge Branch to Master using TeamCity

Create a new VCS repository providing github. I have configured the repository in the root directory of the VCS in the teamcity project. 

<Root project> Contains all other projects	Edit
JavaExamples Java Examples for build and deploy artifacts Edit  Spring Rest Example Standalone Repo Edit Spring Rest Example Standalone Repo -> this repo needs to be set for any change in the branch has to merged to master if build successful Edit

Created a new branch "feature" and would be modifying the code, once the changes are merged and build is successful then it would automatically merge to the master branch.

Modify the VCS in the "Branch Specification" as +:refs/heads/* which lets the teamcity to check for branches other than the master. 

Select "Triggers" and select for auto trigger from the VCS.

Select "Build Features" and select "Automerge changes" in watch build in branch +:feature when new build is created.

Ensure, you have an agent being attached to the VCS to execute the build.
