Repo is a tool developed by Google to manage Android version libraries. Repo encapsulates git in Python, not to replace GIT. It simplifies the management of multiple git version libraries. All version libraries managed with repo need to use git command for operation.
Repo can integrate multiple Git code bases when necessary, upload relevant contents to Gerrit revision control system, and automatically execute some links of Android development workflow.
The repo launcher provides a Python script that can initialize checkout and download the second part, the complete repo tool. The complete repo tool is included in the Android source code checkout. The tool is located in $SRCDIR/.repo/repo /... By default. It can receive forwarded commands from the downloaded repo initiator. Repo uses the manifest file to summarize Git projects into Android super projects.

# Initialize a new client repo init -u: Specifies the web address from which to retrieve the manifest code base. -m: Select the manifest file in the code base. -b: Specify a revision, that is, a specific manifest-branch. eg:repo init -u https://android.googlesource.com/platform/manifest # Synchronize clients to the code base repo sync # Create a new branch repo start # Delete unused local branches repo abandon # Delete merged branches repo prune # Switch branch repo checkout # Displays the status of the current branch repo status # View modifications repo diff # Upload changes to the audit server repo upload # Displays the contents of the manifest file repo manifest
repo init installs repo in the current directory, which creates a. Repo / directory containing the Git code base for repo source code and standard Android manifest files. The. Repo / directory also contains manifest.xml, a symbolic link to the selected manifest in the. repo/manifests / directory. For instructions on updating the manifest, see manifest-format.md.
Manifest files are organized in xml format. A manifest library can contain multiple manifest files and multiple branches, and each manifest file and branch has a corresponding version.
- Remote element: defines a remote version library named korg. The base address of the library is git://172.16.1.31
- Project element: used to define a project. The path attribute indicates the location of the clone in the workspace, and the name attribute indicates the relative path of the remote version Library of the project.
- Default element: set the default remote version Library of each project as Korg, and the default branch as gingerbread exdroid stable. Each project can also define its own remote and revision to override the default configuration.
- The sub element copyfile under the project element defines an attachment action after the project clone, copying the file from src to dest
There are manifest, project, repo folder and other information in the. Repo directory
- manifest: see which branch a module is currently in
