nested exception is NoClassDefFoundError: - spring

Question

Getting the error shown in the title, i believe the error has something to do with my pom.xml file but I'm unsure what.
Here is the complete error
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mapper' defined in class path resource [com/bdonor/accountservice/Config/DynamoDBConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.amazonaws.services.dynamodbv2.datamodeling.DynamoDBMapper]: Factory method 'mapper' threw exception; nested exception is java.lang.NoClassDefFoundError: com/amazonaws/endpointdiscovery/EndpointDiscoveryProviderChain

I also have another project that is working completely fine without the given error, here is it's pom.xml

Any help/suggestions on this matter would be appreciated.

Answer 1

The maven dependency for the aws-java-sdk-dynamodb has inappropriate version value
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk-dynamodb</artifactId>
<version> LATEST </version>
</dependency>
not sure which version you want to use but in your second example you are using 1.11.408
