Configure the repository

Create an empty Git repository:
Open Gerrit server console and navigate to git directory within GERRIT_SITE:
$ cd GERRIT_SITE/git
where
- GERRIT_SITE – the directory that was used as $sitepath during Gerrit installation.
The newly created project directory should be present here and named <given project name>.git
$ ls -l drwxr-xr-x. 7 root root 100 May 10 12:00 All-Projects.git drwxr-xr-x. 7 root root 100 May 10 12:00 All-Users.git drwxr-xr-x. 7 root root 100 May 11 19:26 project.git

Run this command to configure SubGit import:

$ subgit configure --layout auto --trunk TRUNK SVN_URL GIT_REPO

where

SVN_URL – SVN project URL.
GIT_REPO – a path to the new Git repository.
TRUNK – a path, relative to SVN_URL, that leads to an SVN directory serving as the main line of development.

$ subgit configure --layout auto --trunk trunk http://example.com/svn/repository/project ./repo.git

SubGit version 3.2.4 ('Bobique') build #3670

CONFIGURATION SUCCESSFUL

To complete SubGit installation do the following:

1) Adjust Subversion to Git branches mapping if necessary:
/home/user/repo.git/subgit/config
2) Define at least one Subversion credentials in default SubGit passwd file at:
/home/user/repo.git/subgit/passwd
OR configure SSH or SSL credentials in the [auth] section of:
/home/user/repo.git/subgit/config
3) Optionally, add custom authors mapping to the authors.txt file(s) at:
/home/user/repo.git/subgit/authors.txt
4) Run SubGit 'install' command:
subgit install ./repo.git

Specify authors mapping
Configure authors mapping in default authors mapping file:
GIT_REPOS/subgit/authors.txt
Or change core.authors option so that it points to the global authors mapping file.
Find more details about authors mapping in the Authors mapping article.

Import data to the Git repository

$ subgit import GIT_REPO

where

GIT_REPO – a path to the Git repository.

$ subgit import ./project.git

      IMPORT SUCCESSFUL

Clone your new Git repository and start working with it

$ git clone GIT_REPO WORK_TREE

where

WORK_TREE – a path to your working copy.

$ git clone http://gerrit.example.com/user/project.git /home/user/project.git
  Cloning into '/home/user//project.git'...

If Git warns you that you are cloning an empty repository and you don't see your files in the working tree, most probably the automatic branches and tags mapping didn't work correctly. In this case, mapping has to be set manually, see details on mapping in the Branches and tags mapping.
