Java: Bug: The constructor DefaultSemanticTextMemory(MemoryStore, EmbeddingGeneration<String>) refers to the missing type MemoryStore

[normalian]

Describe the bug
I have tried to use AzureAISearch for vector DB, but there is no MemoryStore class across jar files. I believe semantickernel-core-0.2.6-alpha.jar should contain MemoryStore class, but there is no such file.

To Reproduce
Steps to reproduce the behavior:

1. configure pom.xml with following dependencies
2. create following Java code

Expected behavior
Solve missing type MemoryStore error.

Platform

• OS: Windows
• IDE: VS Code
• Language: Java
• Source: maven and following Java code

        OpenAIAsyncClient client = new OpenAIClientBuilder()
                .endpoint(endpoint)
                .credential(new AzureKeyCredential(secretKey))
                .buildAsyncClient();
        OpenAITextEmbeddingGeneration embedding = new OpenAITextEmbeddingGeneration(client, "text-embedding-ada-002");
        DefaultSemanticTextMemory memory = new DefaultSemanticTextMemory(aisearchMemory, embedding);

Additional context
Here is pom.xml dependencies.

I have just found that we are missing classes as follows:

@normalian Hi, so we have had a fair amount of change in the memory area, are you able to test if the latest updates work for you. You can see examples of using datastores at:
