  Compatible Gerrit versions: 2.9.x, 2.10.x, 2.11.x, 2.12.x, 2.13.x, 2.14.x and 2.15.x.
- Move the downloaded file into GERRIT_SITE/plugins directory:
  where
  - GERRIT_SITE – the directory that was used as $sitepath during Gerrit installation.
- Open Gerrit configuration file residing by the following path:
  GERRIT_SITE/etc/gerrit.config
  where
  - GERRIT_SITE – the directory that was used as $sitepath during Gerrit installation.
  Locate receive.timeout parameter and set it to 0:
  [receive] timeout = 0
  if you have Git installed on this machine, it can be done by the following command:
  > git config -f GERRIT_SITE/etc/gerrit.config receive.timeout 0
- Restart the Gerrit daemon:
  - if you have started the Gerrit daemon manually – stop it by Ctrl+C and then start it again:
    > java.exe -jar bin\gerrit.war daemon --console-log
  - if you have Gerrit run as Windows service - restart the service using services.msc console or by commands:
    > sc stop Gerrit > sc start Gerrit
- Check if SubGit plugin is shown in Gerrit:

Configure the repository

Create an empty Git repository:

Open the 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

> dir
 Volume in drive C has no label.
 Volume Serial Number is B86A-EF32
 Directory of c:\gerrit\git
11.05.2017  20:21    <DIR>          .

11.05.2017  17:50    <DIR>          All-Projects.git

11.05.2017  20:14    <DIR>          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 – path to the new Git repository.
TRUNK – path, relative to SVN_URL, that leads to the SVN directory that acts as the main line of development.

> subgit.bat configure --layout auto --trunk trunk http://example.com/svn/repository/project c:\gerrit\git\project.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:
         C:\repo.git\subgit\config
    2) Define at least one Subversion credentials in default SubGit passwd file at:
         C:\repo.git\subgit\passwd
        OR configure SSH or SSL credentials in the [auth] section of:
         C:\repo.git\subgit\config
    3) Optionally, add custom authors mapping to the authors.txt file(s) at:
         C:\repo.git\subgit\authors.txt
    4) Run SubGit 'install' command:
         subgit install "C:\repo.git"

Specify authors mapping
Configure authors mapping in the 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 into the Git repository

Run

> subgit import GIT_REPO

where

GIT_REPO – a path to the Git repository.

> subgit import c:\gerrit\git\project.git

  SubGit version 3.2.4 ('Bobique') build #3670

  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 C:\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 automatic branches and tags mapping didn't work correctly. In this case, mapping has to be set manually, see details on mapping in Branches and tags mapping.
