AWS DynamoDB tutorial does not import certain classes

0 votes

I am trying to follow a tutorial for DynamoDB on the AWS website: http://aws.amazon.com/articles/7439603059327617 I downloaded the file, imported it to Eclipse, imported all the necessary libraries (or literally, all the libraries that came with the GitHub file), but DynamoDBManager.java would keep giving me the dreaded "The import com. amazon... cannot be resolved" error for the following lines:

import com.amazonaws.services.dynamodbv2.model.DynamoDBAttribute; 
import com.amazonaws.services.dynamodbv2.model.DynamoDBHashKey; 
import com.amazonaws.services.dynamodbv2.model.DynamoDBMapper; 
import com.amazonaws.services.dynamodbv2.model.DynamoDBScanExpression; 
import com.amazonaws.services.dynamodbv2.model.DynamoDBTable;
import com.amazonaws.services.dynamodbv2.model.PaginatedScanList;


But library is imported for all other classes such as

import com.amazonaws.services.dynamodbv2.model.AttributeDefinition; 
import com.amazonaws.services.dynamodbv2.model.CreateTableRequest; 
import com.amazonaws.services.dynamodbv2.model.DeleteTableRequest; 
import com.amazonaws.services.dynamodbv2.model.DescribeTableRequest; 
import com.amazonaws.services.dynamodbv2.model.DescribeTableResult; 
import com.amazonaws.services.dynamodbv2.model.KeySchemaElement; 
import com.amazonaws.services.dynamodbv2.model.KeyType; 
import com.amazonaws.services.dynamodbv2.model.ProvisionedThroughput; 
import com.amazonaws.services.dynamodbv2.model.ResourceNotFoundException;
import com.amazonaws.services.dynamodbv2.model.ScalarAttributeType;


Did anyone else run into a similar problem? Could you please direct me in the right direction?!

Thank you in advance & for reading!
