1. Navigate to All > App Engine > ServiceNow Studio.
2. In the file navigator, select the application you want to open.
3. Select App details to open the app in the canvas.
4. Select Source control > Switch branch.

   Option	Description
   Stash local changes	Saves local changes before switching to an alternate branch. You can later merge or discard the saved changes.
   Discard local changes	Permanently deletes all local changes before switching to an alternate branch. If you choose to discard, you will not be able to recover those files. 注: Use caution when discarding local changes. Since all application developers share repository credentials, there is no way to discard just one set of user changes.

タスクの結果

ServiceNow Studio updates the local application to match the branch version from repository.

Create a repository branch

Application developers can create a branch to work on a new version of an existing app in ServiceNow Studio. Creating a branch will result in a new branch being created in the remote repository that is configured for this application. This application, including any uncommitted changes, will switch to the new branch.

手順

1. Follow the steps listed in Add a system property.
2. Add the glide.source_control.default_branch_name property, and specify the default branch name of the Git source control repository to work from.
   For example, default branch names could include pull requests, code commits, and the like. Application developers' work is managed from and saved into the default branch if not otherwise specified. If not changed, this value defaults to sn_instances/<instance_name>.
