------------------------------------------------------------
If we want to solve the "provided" problem, then we may need to remove csv and
json format from the dist too?
It sounds like a regression on the out-of-box experience for SQL users. We have
a long discussion [1] before, and decided to put some light-weight dependencies
into dist. However, now, users have to add dependency filesystem jar manually
which is a frequently used connector in POC.

> Key: FLINK-20098
> URL: https://issues.apache.org/jira/browse/FLINK-20098
> Project: Flink
> Issue Type: Improvement
> Components: API / DataStream
> Reporter: Aljoscha Krettek
> Assignee: Aljoscha Krettek
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.12.0
>
>
> We currently add both {{flink-connector-files}} and {{flink-connector-base}}
> to {{flink-dist}}.
> This implies, that users should use the dependency like this:
> {code}
> <dependency>
> <groupId>org.apache.flink</groupId>
> <artifactId>flink-connector-files</artifactId>
> <version>${project.version}</version>
> <scope>provided</scope>
> </dependency>
> {code}
> which differs from other connectors where users don't need to specify
> {{<scope>provided</scope>}}.
> Also, {{flink-connector-files}} has {{flink-connector-base}} as a provided
> dependency, which means that examples that use this dependency will not run
> out-of-box in IntelliJ because transitive provided dependencies will not be
> considered.
> I propose to just remove the dependencies from {{flink-dist}} and let users
> use the File Connector like any other connector.
> I believe the initial motivation for "providing" the File Connector in
> {{flink-dist}} was to allow us to use the File Connector under the hood in
> methods such as {{StreamExecutionEnvironment.readFile(...)}}. We could decide
> to deprecate and remove those methods or re-add the File Connector as an
> explicit (non-provided) dependency again in the future.
