Source Code Acquisition

Prerequisites

Install the git client and git-lfs, and configure user information.

git config --global user.name "yourname"
git config --global user.email "your-email-address"
git config --global credential.helper store

Run the following commands to install the repo tool:

curl -s https://gitee.com/oschina/repo/raw/fork_flow/repo-py3 > /usr/local/bin/repo  # If you do not have the permission, download the tool to another directory and configure it as an environment variable by running the chmod a+x /usr/local/bin/repo command.
pip3 install -i https://repo.huaweicloud.com/repository/pypi/simple requests

Acquiring Source Code Using the repo Tool

Method 1 (recommended)

Use the repo tool to download the source code over SSH. (You must have an SSH public key for access to Gitee.)

repo init -u git@gitee.com:openharmony/manifest.git -b refs/tags/OpenHarmony-v3.1.6-Release --no-repo-verify
repo sync -c
repo forall -c 'git lfs pull'

Method 2

Use the repo tool to download the source code over HTTPS.

repo init -u https://gitee.com/openharmony/manifest.git -b refs/tags/OpenHarmony-v3.1.6-Release --no-repo-verify
repo sync -c
repo forall -c 'git lfs pull'
