Hi @morningman, sorry for asking questions in unrelated PR comments since the issue channel is not open in this project.

I find the project actually use Apache Maven as build system, but the maven root folder is a sub dir instead of root dir of the repo, do you have a plan to add other things not managed by maven to this repo?

Another question is the sub dir name is spark-doris-connector, but you define the <artifactId>doris-spark-connector</artifactId> in pom.xml, I think it's a little bit confusing.

Hi @pan3793 , thanks for your contribution.

since the issue channel is not open in this project.

I didn't notice that the issue feature is disabled. I will enable it later.

I find the project actually use Apache Maven as build system, but the maven root folder is a sub dir instead of root dir of the repo, do you have a plan to add other things not managed by maven to this repo?

Yes, there may be some other tools not managed by manve.
Because we've just moved this submodule from the Doris main repo.
And before everything settle down, I prefer to use a single dir to save the source code of the connector along.

Another question is the sub dir name is spark-doris-connector, but you define the <artifactId>doris-spark-connector</artifactId> in pom.xml, I think it's a little bit confusing.

Indeed, I will change it later.
