I am using Elasticsearch as a developer. During the compilation process, I found that the download speed of ml-cpp-8.10.0-SNAPSHOT-deps.zip is very slow, and it is not managed by maven, so I cannot use mirror to download. So I'm curious, what is the purpose of this part, and is there any way I can disable this part so it can be skipped during compilation?

Welcome!

I believe this is stored on our elastic repository.

Some questions/thoughts:

- why a snapshot version? You should develop against a stable version
- why 8.10.0? It's too old. You should upgrade to 8.13.3.
- what are you building exactly?

thanks for reply.

- The download of ml-cpp happened after I executed the ./gradlew :run --debug-jvm command. I don't know where to set snapshot or stable.
- Because I was using 8.13.2 before, I don’t know if the ml-cpp package of 8.13.2 became invalid due to the launch of 8.13.3, so I want to find a relatively stable version.
- I want to use debug mode to learn the entire process and source code of elasticsearch.
