What is the plugins directory used for?

[ruanwenjun]

I find there are a directory plugins/json/files/schemas in seatunnel, and find no document about this directory.

Is this directory needed? If needed, we may need to add some description about this. Either, we should delete.

Ok, let's delete this directory, since we have a config directory to show the example.

The plugins directory is used as a default schema dir in json transform plugin. https://seatunnel.apache.org/docs/transform/json#schema_dir-string
