Tool to migrate from IBM RTC to Git

A tool made for migrating code from an existing IBM RTC into a Git repository. Inspired by rtc2git, but written in Java and hopefully faster. It is implemented as scm cli plugin.

Prerequirements

• SCM Tools from IBM. To avoid an account creation on jazz.net site, you could use bugmenot (see also wiki page (configure RTC CLI)

• Eclipse configured with scm tools as target platform (see wiki 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 configure rtc workspaces

• open shell or cmd

• step into the target directory

• load the initial target workspace:

scm load -r <uri> -u <username> -P <password> <TARGET_WORKSPACE>

Execute the actual migration:

scm migrate-to-git -r <uri> -u <username> -P <password> -m <migration.properties> <SOURCE_WORKSPACE> <TARGET_WORKSPACE>

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

Eclipse requirements

In order to have a common coding style across multiple versions of Eclipse import the eclipse-rtccli-format-settings.xml as your first step. Then unpack a SCM Tools as downloaded into the Eclipse workspace directory. As soon you have done this step you are able to import the actual rtc2git.cli.extension project. When you got compile errors, make sure to select rtc2git as your default Target Platform.

Setup Eclipse development environment

In order to enhance the the migration tool or fix a bug that you may encounter here are the steps to set up a development environment

• Configure SCMTools Target Platform described here in the 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

• 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
