Here you have the steps to compile and run an RSK node on Mac.

This page is organized in this way:


First of all, you will need to install:

Dependency Details
Git for Mac Download this Git command line tool
Java 8 JDK Follow the steps to install Java. To check if installation went correctly, check the version with command: java -version.
IntelliJ IDEA Community Install this Java IDE

To complete Java installation you need to configure the JAVA_HOME environment variable. You have to run the following commands on terminal:

➜ /usr/libexec/java_home

➜ export JAVA_HOME=`/usr/libexec/java_home`

➜ launchctl setenv JAVA_HOME `/usr/libexec/java_home`

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 these commands on Git command line:

git clone --recursive
cd rskj
git checkout tags/IRIS-3.2.0 -b IRIS-3.2.0

Note: It is better to download the code into a short path.

Ensure the security chain

Ensure the security chain of the downloaded source code.

Get external dependencies

Before you can launch IntelliJ IDEA, there is an important step. Browse in your RSKj cloned directory and then launch with the following terminal command:


This will download and set important components (e.g. Gradle Wrapper).

Compiling the node

Now, you can launch IntelliJ IDEA. When IntelliJ IDEA is launched you should have a window with different choices.

  • Choose Import project.
  • Browse in the RskJ downloaded code the file rskj\build.gradle and select it. Click NEXT.
  • Within the dialog select Use default gradle wrapper and then click Finish. Keep IntelliJ IDEA open.


IDEA Build/Run configuration

We need to create a new configuration profile to run the node from 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
  • 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)

Running the node

We are ready to run the node using IDEA, just press the Start (green arrow) 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 :)

You’re joined to Mainnet by default.

If you want to switch the network, add:

  • For Testnet: --testnet
  • For Regtest: --regtest

Inside the field Program arguments in your run configuration.

Any problems?
