It seems like you're looking for a Java client to interact with the Upstash Vector DB. However, I couldn't find any information on a specific "Vector Vector HD HD" in my search results.

But, I did find an HTTP/REST based Vector DB client built on top of Upstash REST API, which is available as a npm package: @upstash/vector. You can download the Java jar file for this package using the following command:

npm install @upstash/vector

This will download the vector-<version>.jar file to your project directory. You can then add it to your classpath and use the VectorClient class to interact with the Upstash Vector DB.

Please note that you'll need to check the documentation for the specific version of the package you're using, as the API might have changed.
