For now, we can just create the package, i.e., com.example.demo inside the hazelcast directory. Then, just cd to that directory. We will look at other files in the upcoming sections.

Installing Hazelcast

Installing Hazelcast simply involves adding a JAR file to your build file. POM file or build.gradle based on whether you are using Maven or Gradle respectively.

If you are using Gradle, adding the following to build.gradle file would be enough −

dependencies {

   compile "com.hazelcast:hazelcast:3.12.12”

}

POM for the tutorial

We will use the following POM for our tutorial −

<?xml version="1.0" encoding="UTF-8"?>
