Here you have the steps to compile and run a RSK node on Mac.
This page is organized in this way:
Pre-requisites
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 JAVA_HOME 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 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.
Ensure the security chain
Ensure the security chain of the downloaded source code as explained here.
Get external dependencies
Before you can launch IntelliJ IDEA, there is an important step.
Browse in your RskJ cloned directory and then launch configure.sh
with the following terminal command:
./configure.sh
.
This will download and set important components (e.g. Gradle Wrapper).
Compiling and running 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 opened.
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: rskj/rskj-core/src/main/resources/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-conf/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)
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 :)
