             Summary: Don't add flink-connector-files to flink-dist
                 Key: FLINK-20098
                 URL: https://issues.apache.org/jira/browse/FLINK-20098
             Project: Flink
          Issue Type: Bug
          Components: API / DataStream
            Reporter: Aljoscha Krettek
            Assignee: Aljoscha Krettek
             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.
