# Introduction
|
|
|
|
This source repository contains explorations of various design concepts the R3 DLG is exploring.
|
|
|
|
Things you need to know:
|
|
|
|
* The main code documentation is in the form of a website in the git repository. Load [the website](docs/build/html/index.html)
|
|
in the `docs/build/html` directory to start reading about what's included, how to get set up, and to read a tutorial
|
|
on writing smart contracts in this framework.
|
|
|
|
* The architecture documentation is on the [Architecture Working Group Wiki](https://r3-cev.atlassian.net/wiki/display/AWG/Architecture+Working+Group) site - please
|
|
refer to that for an explanation of some of the background concepts that the prototype is exploring.
|
|
|
|
* The code is a JVM project written mostly in [Kotlin](https://kotlinlang.org/), which you can think of as a simpler
|
|
version of Scala (or alternatively, a much better syntax for Java). Kotlin can be learned quickly and is designed
|
|
to be readable, so you won't need to know it very well to understand what the code is doing. If you'd like to
|
|
add new features, please read its documentation on the website.
|
|
|
|
There is also Java code included, to demonstrate how to use the framework from a more familiar language.
|
|
|
|
* For bug tracking we use [JIRA](https://r3-cev.atlassian.net/secure/RapidBoard.jspa?rapidView=9&projectKey=PD). For source control we use this BitBucket
|
|
repository. You should have received credentials for these
|
|
services as part of getting set up. If you don't have access, please contact Richard Brown or James Carlyle.
|
|
|
|
* There will be a mailing list for discussion, brainstorming etc called [r3dlg-awg](https://groups.google.com/forum/#!forum/r3dlg-awg).

# Instructions for installing prerequisite software
|
|
|
|
## JDK for Java 8
|
|
|
|
Install the Oracle JDK 8u45 or higher. It is possible that OpenJDK will also work but we have not tested with this.
|
|
|
|
## Using IntelliJ
|
|
|
|
It's a good idea to use a modern IDE. We use IntelliJ. Install IntelliJ version 15 community edition (which is free):
|
|
|
|
https://www.jetbrains.com/idea/download/
|
|
|
|
Upgrade the Kotlin plugin to the latest version (1.0-beta-2423) by clicking "Configure > Plugins" in the opening screen,
|
|
then clicking "Install JetBrains plugin", then searching for Kotlin, then hitting "Upgrade" and then "Restart".
|
|
|
|
Choose "Check out from version control" and use this git URL
|
|
|
|
https://your_username@bitbucket.org/R3-CEV/r3prototyping.git
|
|
|
|
Agree to the defaults for importing a Gradle project. Wait for it to download the dependencies.
|
|
|
|
Right click on the tests directory, click "Run -> All Tests" (note: NOT the first item in the submenu that has the gradle logo next to it).
|
|
|
|
The code should build, the unit tests should show as all green.
|
|
|
|
You can catch up with the latest code by selecting "VCS -> Update Project" in the menu.
|
|
|
|
## IntelliJ Troubleshooting
|
|
If on attempting to open the project, IntelliJ refuses because SDK was not selected, do the following:
|
|
|
|
Configure -> Project Defaults -> Project Structure
|
|
|
|
on that tab:
|
|
|
|
Project Settings / Project
|
|
|
|
click on New… next to the red <No SDK> symbol, and select JDK. It should then pop up and show the latest JDK it has found at something like
|
|
|
|
jdk1.8.0_xx…/Contents/Home
|
|
|
|
Also select Project language level: as 8. Click OK. Open should now work.
|
|
|
|
## Accessing Source Without an IDE
|
|
|
|
If you don't want to explore or modify the code in a local IDE, you can also just use the command line and a text editor:
|
|
|
|
git clone https://your_username@bitbucket.org/R3-CEV/r3prototyping.git
|
|
|
|
You will need to have your Bitbucket account set up already from R3. Then:
|
|
|
|
cd r3prototyping
|
|
|
|
Run the following to run the unit tests:
|
|
|
|
./gradlew test
|
|
|
|
For the first time only, this will download and configure Gradle.
|
|
Run "git pull" to upgrade
|
|
|
|
## Starting point - the Tutorial
|
|
|
|
We have prepared a comprehensive tutorial.
|
|
One you have access to the source, open the following in a browser:
