A key part of setting up your continuous integration build process is to specify the code repositories that Bamboo will work with. You can specify repositories at the following levels in Bamboo:
The recommended approach is to set up linked source repositories at the global level, described below.
Linked repositories are available globally to all plans and jobs configured on the Bamboo server. Doing this can save you from having to reconfigure the source repositories in multiple places if these ever change - any changes to a linked repository are applied to every plan or job that uses that repository.
You need the 'Create plan' or 'Admin' global permission to configure linked repositories.
If you need to use an unsupported type of repository, a number of third-party Source Repository plugin modules are available (e.g. the ClearCase plugin). You can also write a Source Repository Module plugin to enable Bamboo to connect to your repository.
Note that shared source repositories are no longer the preferred way to share repository configuration between plans. Use linked repositories instead!
When you create a new plan, the source repository you specify becomes the default. It is used by the plan's 'Default Job' and can be used by other jobs added to this plan.
Please note that In the long term, Atlassian plans to deprecate the repository configuration defined against a plan. These configurations can be converted to linked repositories by clicking Convert to linked repository in each plan's repository configuration page.
You can specify additional repositories for a Bamboo plan to work with at the job level, perhaps for tasks in later stages of the build.
You add the Source Code Checkout task to a job to configure a particular repository for just that job. See Checking out code for details about configuring the Source Code Checkout task.
