Recreating repository requires reconfiguring branches in Source repository tab

Summary

• Pre-existent plan branches do not get updated when replaced repository configuration.

Environment

• Bamboo v5.13.0.1

Steps to Reproduce

Git repository has two branches (e.g. master, feature/branch)

1. create a Project / Plan (e.g PROJ-PLAN)
2. create a Git repository (e.g. Repository A) under Plan configuration >> Repositories tab or Bamboo administration >> Build resources >> Linked repository adding the linked repository to the plan
3. add a Source Code Checkout task
4. run the build plan
5. go to Plan configuration >> Branches tab and add a new branch (e.g. PROJ-PLAN0)
6. run a build from this branch
7. delete the repository in Bamboo
8. add the same Git repository with a different name (e.g Repository B) under Plan configuration >> Repositories tab or Bamboo administration >> Build resources >> Linked repository adding the linked repository to the plan

Subversion does not have branches

1. instead of adding Git repository in step 8 from above, repeat steps 7-8 but adding a Subversion repository instead.

Expected Results

• Branches should be disabled

Actual Results

• When using same repository type
  After deletion you can notice the Plan will be using Repository B whereas the Branch will be using Repository A configurartion

  FULL_KEY	BUILD_TYPE	VCS_LOCATION_ID	NAME	PLUGIN_KEY
  PROJ-PLAN0	CHAIN_BRANCH	3047425	Repository A	com.atlassian.bamboo.plugins.atlassian-bamboo-plugin-git:git
  PROJ-PLAN	CHAIN	3047426	Repository B	com.atlassian.bamboo.plugins.atlassian-bamboo-plugin-git:git

• When using different repository type

  FULL_KEY	BUILD_TYPE	VCS_LOCATION_ID	NAME	PLUGIN_KEY
  PROJ-PLAN0	CHAIN_BRANCH	3047425	Repository A	com.atlassian.bamboo.plugins.atlassian-bamboo-plugin-git:git
  PROJ-PLAN	CHAIN	3047426	Repository B	com.atlassian.bamboo.plugin.system.repository:svn

Workaround

• Make sure the branches are are pointing to the correct repository under Branches >> Source repository
  • Under Branches >> Source repository, uncheck Override the plan's default repository and Save repository
  • Under Branches >> Source repository, check Override the plan's default repository and reconfigure branch.
