Here you have the steps to compile and run a RSK node on Windows.

This page is organized in this way:

• Pre-requisites

• Get the source code

• Ensure the security chain

• Get external dependencies

• Compiling and running the node

Pre-requisites

First of all, you will need to install:

Dependency	Link	Details
Git for Windows	Git	Command line tool
Java JDK 8	Java 8 JDK	JAVA_HOME variable needs to be set.
IntelliJ IDEA	IntelliJ IDEA	Java IDE

Get the source code

Using the installed command-line tool Git, you need to retrieve (or clone) the RskJ Github source code from here.

Run this command on Git command line:

git clone --recursive https://github.com/rsksmart/rskj.git

Note: it is better to download the code into a short path, like C:/RskjCode.

Ensure the security chain

Ensure the security chain of the downloaded source code as explained here. Use Git Bash to run the commands on Windows.

Get external dependencies

Now, you have to double click over the configure.sh file located in rskj/ folder. It will install dependencies that the project need to compile, running over Git Bash (installed with Git for Windows -see Pre-requisites-).

Compiling and running the node

After opening IDEA we need to load the RskJ project, this can be done by using the Import project option in IDEA.

To do that follow the next steps:

• Go to File -> New -> Project from Existing Sources...
• Browse in the RskJ downloaded code the file rskj\build.gradle and select it.
• Within the dialog select Use default gradle wrapper and then press Finish.

IDEA Build/Run configuration

We need to create a new configuration profile to run the node from IDEA. Part of the configuration information that needs to be provided is related to the node itself, you can find a sample configuration file on: /classes/production/rskj-core/config/rsk-sample.conf. Some settings need to be initialized and you can learn to do that here.

Next step is to create a new configuration profile on IDEA, that can be done by clicking on Run -> Edit Configurations or as shown in the following picture:

Then set the options as shown below:

• Main Class: co.rsk.Start
• VM Options: -Drsk.conf.file=/path/to/rsk-sample.conf
• Working directory: /path/to/code/rskJ
• Use classpath of module: rskj-core_main
• JRE need to be set as: Default (1.8 - SDK of 'rsk-core_main' module)

Note: - If it isn't configured the default JDK, you have to set it in: File -> Project Structure. - If the IDE doesn't recognize the configuration options, open rskj/rskj-core/build.gradle and sync it from Gradle tab.

Running the node

We are ready to run the node using IDEA, just press the Start button at the right of the configuration we've just created.

If everything is OK you should see the debug information like that:

And yes! Congratulations! Now you're running a local RSK node :)
