Installing Repo

Repo is a tool that makes it easier to work with Git in the context of Android. For more information about Repo, see Version Control.

To install, initialize, and configure Repo, follow these steps:

• Make sure you have a bin/ directory in your home directory, and that it is included in your path:

  $ mkdir ~/bin
  $ PATH=~/bin:$PATH
  

• Download the Repo script and ensure it is executable:

  $ curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
  $ chmod a+x ~/bin/repo
  

• For version 1.17, the SHA-1 checksum for repo is ddd79b6d5a7807e911b524cb223bc3544b661c28

Initializing a Repo client

After installing Repo, set up your client to access the android source repository:

• Create an empty directory to hold your working files. If you're using MacOS, this has to be on a case-sensitive filesystem. Give it any name you like:

  $ mkdir WORKING_DIRECTORY
  $ cd WORKING_DIRECTORY
  

• Run repo init to bring down the latest version of Repo with all its most recent bug fixes. You must specify a URL for the manifest, which specifies where the various repositories included in the Android source will be placed within your working directory.

  $ repo init -u https://android.googlesource.com/platform/manifest
  

  To check out a branch other than "master", specify it with -b:

  $ repo init -u https://android.googlesource.com/platform/manifest -b android-4.0.1_r1
  

• When prompted, please configure Repo with your real name and email address. To use the Gerrit code-review tool, you will need an email address that is connected with a registered Google account. Make sure this is a live address at which you can receive messages. The name that you provide here will show up in attributions for your code submissions.

A successful initialization will end with a message stating that Repo is initialized in your working directory. Your client directory should now contain a .repo directory where files such as the manifest will be kept.

Getting the files

To pull down files to your working directory from the repositories as specified in the default manifest, run

$ repo sync
