Spring Cloud Bus with rabbit - Application Failed to Start

Question

I'm triying to create a Config Server that listens to Git event and streams events to client. I followed several examples and also the documentation, but I cant manage to get application to start. I guess I have a problem with spring boot and cloud versions.

It is important to mention im running rabbitmq with docker.

This is my build.gradle

plugins {
    id 'org.springframework.boot' version '2.5.3'
    id 'io.spring.dependency-management' version '1.0.11.RELEASE'
    id 'java'
}

group = 'com.pal.pocs.config'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'

configurations {
    compileOnly {
        extendsFrom annotationProcessor
    }
}

repositories {
    mavenCentral()
}

ext {
    set('springCloudVersion', "2020.0.3")
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-actuator'
    implementation 'org.springframework.cloud:spring-cloud-config-server'
    implementation 'org.springframework.cloud:spring-cloud-starter-bus-amqp'
    compileOnly 'org.projectlombok:lombok'
    annotationProcessor 'org.projectlombok:lombok'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

dependencyManagement {
    imports {
        mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
    }
}

test {
    useJUnitPlatform()
}

And this is the exception Im getting:

Action:

Correct the classpath of your application so that it contains a single, compatible version of org.springframework.integration.amqp.inbound.AmqpInboundChannelAdapter

Does anyone has a clue about where is the missconfiguration?

Answer 1

Well, I figured out

I turns out that Spring Cloud 2020.0.3 is supported by Spring Boot 2.4.6

So I downgraded to 2.4.6 and application started!

Hope it is helpfull for someone else
