DynamoDB Enhanced v. 2.15.41 putItem - getItem generates java.lang.NoClassDefFoundError #2198
Description
When using DynamoDB version 2.15.41, but even the older versions, with the play framewok 2.8 (java) it throws a NoClassDefFoundError when you set the Table Schema via annotated class or via bean.
Describe the bug
I'm trying to create a simple registration/login application with the support of DynamoDB and Play Framework with java.
I downloaded the last play java seed from the official site and added the dependencies for DynamoDb and DynamoDB enhanced v. 2.15.41.
I wrote some simple API's to call
Create - Put - Get for the items. But I'm not able to put or get items from the table
What I mean is that if I define a table as following it will throw a NoClassDefFound when used:
DynamoDbAsyncClient dynamoDbAsyncClient = DynamoDbAsyncClient .builder() .endpointOverride(URI.create("http://localhost:8000")) .build(); DynamoDbEnhancedAsyncClient enhancedAsyncClient = DynamoDbEnhancedAsyncClient .builder() .dynamoDbClient(dynamoDbAsyncClient) .build(); return enhancedAsyncClient.table("Customer", TableSchema.fromClass(Customer.class)); @DynamoDbBean public static class Customer { private String id; private String name; private String email; private Instant regDate; @DynamoDbPartitionKey public String getId() { return this.id; } @DynamoDbSortKey public String getCustName() { return this.name; } //Omitted the getters and setters for brevity } Expected Behavior
I should be able to put and get items correctly.
Current Behavior
When you run this code it's going to throw the exception.
Key key = Key.builder() .partitionValue("id103") .sortValue("Susan Blue") .build(); // Get the item by using the key return table.getItem(r -> r.key(key)) ERROR akka.actor.ActorSystemImpl

omitted Steps to Reproduce
A public repository with the code could be found here:
https://github.com/Max161/AWS_DynamoDB_ClassNotFound_Error
To run the code use sbt run command in the main folder.
Than you can use postman to call the API:
/createtable
/getItem
/putItem
