Basic project setup for gradle project should look like this:

build.gradle

Most important part here is spring-boot-starter and adapter-sdk dependencies.

Example file can be found here.

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter'
    implementation group: "com.stibo.leap", name: "adapter-sdk", version: "0.0.1-SNAPSHOT", changing: true

    testImplementation 'org.springframework.boot:spring-boot-starter-test'
    testImplementation 'org.springframework.kafka:spring-kafka-test'
    // Jupiter
    testImplementation 'org.junit.jupiter:junit-jupiter-api:5.8.2'
    testImplementation 'org.junit.jupiter:junit-jupiter-params:5.8.2'
    testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.8.2'
}

spring.application.name: sdk-demo-adapter

application.yaml

Basic configuration should contain application name. This name will be used to register with Eureka and connect to the correct Kafka topics. No other configuration should be required to run adapter with default configs.

Example file can be found in demo adapter implementation here.

spring.application.name: sdk-demo-adapter

Application.java

Main class for adapter application. No additional configuration should be needed to run adapter.

Example file can be found in demo adapter implementation here.

package com.stibo.leap.sdkdemo;

import org.springframework.boot.SpringApplication;
import com.stibo.leap.adapter.AdapterApplication;

@AdapterApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

ApplicationTest.java

This simple test is the easiest way to check if all required components and configurations are in place. If not, some useful errors should be reported that will help to solve the issue - we will talk about it in the next section.

Example file can be found in demo adapter implementation here.

package com.stibo.leap.sdkdemo;

import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.kafka.test.context.EmbeddedKafka;

@SpringBootTest(classes = Application.class)
@EmbeddedKafka(partitions = 1, brokerProperties = { "listeners=PLAINTEXT://localhost:9092", "port=9092" })
public class ApplicationTest {
    @Test
    public void contextLoads() {
    }
}
