Improve/Fix documentation to correctly define aspectLibrary in pom.xml for Powertool idempotency for v2

[Vadym79]

What were you searching in the docs?

For preview of v2 this page states that the following dependency needs to be defined in the pom.xml

     <plugin>
             <aspectLibraries>
                 <aspectLibrary>
                     <groupId>software.amazon.lambda</groupId>
                     <artifactId>powertools-idempotency-dynamodb</artifactId>
                 </aspectLibrary>
             </aspectLibraries>
    </plugin>

My tests revealed that instead of artifact id "powertools-idempotency-dynamodb", artifact id "powertools-idempotency-core" needs to be defined, see my working example.

Is this related to an existing documentation section?

https://docs.powertools.aws.dev/lambda/java/preview/utilities/idempotency/

How can we improve?

My tests revealed that instead of artifact id "powertools-idempotency-dynamodb", artifact id "powertools-idempotency-core" needs to be defined, see my working example.

Got a suggestion in mind?

User powertools-idempotency-core instead

Acknowledgment

• I understand the final update might be different from my proposed suggestion, or refused.

I tested this today and can confirm that this is a miss in the v2 documentation. As part of #1467 we split the idempotency module into submodules to foster clearer separation between persistence stores and the idempotency logic.

We keep the logic including the AspectJ weaving in the core module now while the persistence store is split into a corresponding DynamoDB sub-module. Similar to what you did in your example (thanks for providing this 🙏) we should modify the documentation.

Hey @Vadym79, thanks again for reporting this. I deployed an update to the docs preview website fixing this bug: https://docs.powertools.aws.dev/lambda/java/preview/utilities/idempotency/#installation.
