It seems like you're looking for a Java client library to interact with the Azure AI Projects API. Unfortunately, I couldn't find any information on a specific "v2 API jar" that includes vector product and PNG product features.

However, I can suggest using the @azure/ai-projects client library, which is available on NPM Registry. You can install it using npm:

npm install @azure/ai-projects

This library provides a Java client for interacting with Azure AI Projects, but I couldn't find any information on its documentation or GitHub repository.

If you're looking for a specific feature like vector product and PNG product, you might want to consider using the @openapitools/openapi-generator-cli package, which can generate API client libraries (SDK generation) based on an OpenAPI Spec. However, this would require more configuration and setup than using the @azure/ai-projects library.

I apologize for not being able to provide a more specific answer. If you have any further questions or need help with setting up one of these libraries, feel free to ask!
