= Tool to migrate from IBM RTC to Git :project-full-path: rtcTo/rtc2gitcli :github-branch: master :rtcversion: 6.0.4 :rtc2gitwiki: https://github.com/rtcTo/rtc2git/wiki :rtc2gitcliwiki: https://github.com/rtcTo/rtc2gitcli/wiki image:https://img.shields.io/badge/license-MIT-blue.svg["MIT License", link="https://github.com/{project-full-path}/blob/{github-branch}/LICENSE"] image:https://img.shields.io/badge/Java-8-blue.svg["Supported Versions", link="https://travis-ci.org/{project-full-path}"]

A tool made for migrating code from an existing https://jazz.net/products/rational-team-concert/[IBM RTC] into a Git repository. Inspired by https://github.com/{project-full-path}[rtc2git], but written in Java and hopefully faster. It is implemented as scm cli plugin.

== Prerequirements

• https://jazz.net/downloads/rational-team-concert/releases/{rtcversion}?p=allDownloads[SCM Tools] from IBM. To avoid an account creation on jazz.net site, you could use http://bugmenot.com/[bugmenot] (see also wiki page ({rtc2gitwiki}/configure-RTC-CLI[configure RTC CLI])
• Eclipse configured with scm tools as target platform (see wiki {rtc2gitcliwiki}/configure-target-platform[configure scm tools target platform])

== Usage

• create an source RTC workspace with flow target and components as wanted -> SOURCE_WORKSPACE
• create an target RTC workspace with SOURCE_WORKPSACE as flow target -> TARGET_WORKSPACE
• check comments at {rtc2gitcliwiki}/configure-rtc-workspaces[configure rtc workspaces]
• open shell or cmd
• step into the target directory
• load the initial target workspace:

[source,bash]

scm load -r -u -P

Execute the actual migration:

[source,bash]

scm migrate-to-git -r -u -P -m

== How does it work?

1. It initalizes an empty git repository and clones it
2. In this repository, it loads TARGET_WORKSPACE RTC workspace
3. Every change set is accepted
4. If there is a baseline on the change set, a tag is created on git
5. The change set is committed to git

=== Setup Eclipse development environment In order to enhance the the migration tool, fix a bug that you may encounter or simply want to run it from your eclipse, here are the steps to set up a development environment:

• Import Code Style (Window->Preferences->Java->Code Style->Formatter) eclipse-rtccli-format-settings.xml in order to have a common coding style (you can skip this step if you only want to run it)
• Configure SCMTools Target Platform described here in the {rtc2gitcliwiki}/configure-target-platform[wiki]. Point to the folder where your scm.exe/lscm.bat is (If you use eclipse classic aka non javaee eclipse, install the Eclipse Plugin Development Tools as described {rtc2gitcliwiki}/configure-target-platform#help---there-is-no-target-platform[here])
• Clone this repo and import it in eclipse as maven project
• Open pom.xml and follow the hint to install the missing maven connector
• Update maven project using [ALT]+[F5]
• By this point the project shouldnt contain any errors (make sure you have still your created target platform in window preference selected)
• You should have an launch-configuration named rtc2git -> start it
• In your console window you should see "Help for: scm migrate-to-git"
• Open the launch-config and edit the command in arguments/program arguments

In case you use RTC Version 6+ (and have the error Problem running 'help', unknown Subcommand...), please follow the instructions of this https://github.com/rtcTo/rtc2gitcli/issues/44#issuecomment-396727582[issue-comment] in order to run rtc2gitcli.
