java.lang.ClassNotFoundException: com.amazonaws.ClientConfigurationFactory

Hi,

I am trying to setup this library in my existing Spring boot project but I getting the following error.

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.amazonaws.services.dynamodbv2.AmazonDynamoDB]: Factory method 'amazonDynamoDB' threw exception; nested exception is java.lang.NoClassDefFoundError: com/amazonaws/ClientConfigurationFactory

I am using Spring Boot 1.4 and I just added the following to my pom.xml

<dependency>
            <groupId>com.github.derjust</groupId>
            <artifactId>spring-data-dynamodb</artifactId>
            <version>4.4.1</version>
        </dependency>

Should I add the AWS SDK separately to my pom.xml too?

Do you have an example project setup that I can facilitate the basic functionality of the homepage README? Messing around with alot of transitive dependancies can be abit of a minefield.

can you please post the output of mvn dependency:tree?
Sounds to me that you have multiple (transitive) dependencies of AWS SDK on your classpath.

[tomhughesnice]

You are correct. I already have spring-cloud-aws-context on the classpath.

I have just excluded the bundled dynamodb sdk

<dependency>
    <groupId>com.github.derjust</groupId>
    <artifactId>spring-data-dynamodb</artifactId>
    <version>4.4.1</version>
    <exclusions>
        <exclusion>
            <groupId>com.amazonaws</groupId>
            <artifactId>aws-java-sdk-dynamodb</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-dynamodb</artifactId>
    <version>${aws-java-sdk-dynamodb.version}</version>
</dependency>

Out of curiosity:

• Can you tell from which dependency this was added?
• Can you tell with version the other library uses? so between which AWS SDK versions was the clash?
