   • Move the downloaded file into plugins directory:

     $ mv ./subgit-gerrit-plugin-1.0.0-EAP4.jar GERRIT_SITE/plugins

     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 Gerrit daemon:

     $ GERRIT_SITE/bin/gerrit.sh restart

     where

     • GERRIT_SITE – the directory that was used as $sitepath during the Gerrit installation.

     $ /gerrit/bin/gerrit.sh restart Stopping Gerrit Code Review: OK Starting Gerrit Code Review: OK

     
     

   • Check SubGit plugin is showed in Gerrit:
     
     

2. Configure the repository
   
   
   • Create empty Git repository:
     
     

   • Open Gerrit server console and step into 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 a new Git repository.
     • TRUNK     – a path, relative to SVN_URL, that leads to an SVN directory that plays the role of the main line of development.

     $ subgit configure --layout auto --trunk trunk http://example.com/svn/repository/project /gerrit/site/project.git SubGit version 3.2.4 ('Bobique') build #3670 Configuring writable Git mirror of remote Subversion repository: Subversion repository URL : http://example.com/svn/repository/project Git repository location : ./repo.git Detecting peg location... Authentication realm: <http://example.com:80> Subversion Repository Username [user]: user Password [user]: Peg location detected: r10248 project/trunk Fetching SVN history... Done. Growing trees... Done. Project origin detected: r1 project/trunk Building branches layouts... Done. Combing beards... Done. Generating SVN to Git mapping... Done. 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_REPO/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.

     
     

   • Specify a username and password that are used by SubGit to access the SCN repository. Edit passwd file:

     GIT_REPO/subgit/passwd

     By default, there's only subgit secret credential pair. Replace it with a username and its corresponding password.

     There are several methods to configure authentication to access SVN server, but we use a plain text password file here to simplify the guide. See more authentication methods in SVN Authentication if this method does not fit your needs.

      

3. Establish a two-way mirror between SVN and Gerrit by the following command:
   
   

   $ subgit install GIT_REPO

   where 

       GIT_REPO – a path to the Git repository.

   $ subgit-3.2.4/bin/subgit install ./project.git SubGit version 3.2.4 ('Bobique') build #3670 Translating Subversion revisions to Git commits... Subversion revisions translated: 10248. Total time: 2 hours 15 minutes 24 seconds. INSTALLATION SUCCESSFUL

   
   

4. When the command completed, the mirror is established and data from SVN is translated to Gerrit, so you can clone your new Git repository and start to work with it:
   
   

   $ git clone GERRIT_URL WORK_TREE

   where

   • GERRIT_URL – the new Gerrit project URL.
   • 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'... Password for 'http://gerrit.example.com': remote: Counting objects: 99, done. remote: Compressing objects: 100% (39/39), done. remote: Total 99 (delta 50), reused 99 (delta 50) Unpacking objects: 100% (99/99), done.

   
   

   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.

   
   

5. Try and buy.
   
   

   Note: the trial period for SubGit mirror is 30 days, after that period you should buy a license key at https://subgit.com/pricing.

   Once you receive an email with a license key, upload this license key to your server and run the following command:

   $ sudo subgit register --key subgit.key GIT_REPO

   where

        GIT_REPO – a path to your newly created Git repository.

   $ sudo subgit register --key subgit.key /gerrit/site/project.git SubGit version 3.2.4 ('Bobique') build #3670 Registration information: Registered for: Example company Purchase ID: OS-111111111111111 Expiration date: April 23, 2028 You may use this key to register 9 more repositories (out of 10). REGISTRATION SUCCESSFUL Thank you for registering SubGit! Visit http://www.subgit.com/ in case you have any questions and for more information on SubGit.
