----------------------------------------
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.
