Here is an example how to quickly start a new Hazelcast Project with Gradle.

What’s in a box?

• Gradle Wrapper FTW! No need to have Gradle installed.

• build.gradle with Hazelcast repositories (including Enterprise and SNAPSHOTS)

• Easy Hazelcast version management with gradle.properties

• Hazelcast dependencies (including Testing Framework)

• UberJar configuration via shadow Gradle plugin.

1. This file

2. JVM properties, Hazelcast version configs

3. Gradle wrapper

4. Entry point of your Hazelcast application

5. Hazelcast server configuration file

Run your Hazelcast application

./gradlew run #(1)

1. This will use Starter.java to start your Hazelcast application. This can be changed in build.gradle. Look for mainClassName property.

Produce UberJar

./gradlew shadowJar #(1)

1. This command will produce executable jar with Starter.class as Main-Class. This can be changed in build.gradle. Look for mainClassName property.

Start Hazelcast Member Node

To start Hazelcast member node. By default, a member will use hazelcast.xml from src/main/resources folder.

Gradle

./gradlew execute -PmainClass=com.hazelcast.core.server.StartServer
