Spring boot failing to start with Spring Cloud AWS Core dependency

I am writing a spring boot app that accesses stuff from an s3 bucket, but I get a NoClassDefFoundError when I use the starter spring-cloud-starter-aws dependency from the spring initializer.

Am I missing some other dependency here?

Below are my dependencies.

<dependencies>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-amqp</artifactId>
    </dependency>
    <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-starter-aws</artifactId>
    </dependency>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-data-cassandra</artifactId>
    </dependency>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-integration</artifactId>
    </dependency>

    <dependency>
      <groupId>org.projectlombok</groupId>
      <artifactId>lombok</artifactId>
      <optional>true</optional>
    </dependency>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-test</artifactId>
      <scope>test</scope>
    </dependency>
</dependencies>

I also defined the dependencyManagement block for spring-cloud-dependencies and use Edgware.SR1 as my spring-cloud-version.

My app fails with the following error when starting up.

2018-01-24 12:20:25.642  INFO 1980 --- [           main] utoConfigurationReportLoggingInitializer : 

Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled.
2018-01-24 12:20:25.666 ERROR 1980 --- [           main] o.s.boot.SpringApplication               : Application startup failed

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to process import candidates for configuration class [com.art.productattribution.consumerintegration.ConsumerIntegrationApplication]; nested exception is java.lang.NoClassDefFoundError: com/amazonaws/AmazonClientException
    at org.springframework.context.annotation.ConfigurationClassParser.processImports(ConfigurationClassParser.java:616) ~[spring-context-4.3.13.RELEASE.jar:4.3.13.RELEASE]

Not sure what am I missing here? Please let me know if you need any more details with this. The version of spring boot I am using is 1.5.9.RELEASE

You need to include dependency mentioned by @alltej. Also you need to add below property in application.properties file if you are running on local.

cloud.aws.stack.auto=false

The correct dependency is the spring-cloud-aws-context. Add the following in your pom file (version 1.2.2 as of Nov 22, 2017):

<!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-aws-context -->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-aws-context</artifactId>
    <version>1.2.2.RELEASE</version>
</dependency>

Below are the Spring Cloud AWS modules:

Spring Cloud AWS Core is the core module of Spring Cloud AWS providing basic services for security and configuration setup. Developers will not use this module directly but rather through other modules. The core module provides support for cloud based environment configurations providing direct access to the instance based EC2 metadata and the overall application stack specific CloudFormation metadata.

Spring Cloud AWS Context delivers access to the Simple Storage Service via the Spring resource loader abstraction. Moreover developers can send e-mails using the Simple E-Mail Service and the Spring mail abstraction. Further the developers can introduce declarative caching using the Spring caching support and the ElastiCache caching service.

Spring Cloud AWS JDBC provides automatic datasource lookup and configuration for the Relational Database Service which can be used with JDBC or any other support data access technology by Spring.

Spring Cloud AWS Messaging enables developers to receive and send messages with the Simple Queueing Service for point-to-point communication. Publish-subscribe messaging is supported with the integration of the Simple Notification Service.

It seems com.amazonaws.AmazonClientException is not found in the classpath. I think you can add the following dependency in your POM.xml file to solve this issue.

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-aws-core</artifactId>
    <version>1.2.2.RELEASE</version>
</dependency>
