Paras Negi deleted comment on FLINK-39426:
------------------------------------
was (Author: JIRAUSER312767):
{{flink-connector-jdbc}} stops at 3.3.0-1.20 — that was the umbrella-jar
(bundling {{-core}} + all dialects), and it was explicitly removed as
deprecated in commit
[891c0e9|https://github.com/apache/flink-connector-jdbc/commit/891c0e9cd373]
("Remove deprecated flink-connector-jdbc module") as part of [PR
#153|https://github.com/apache/flink-connector-jdbc/pull/153].
The Flink 2.0 release itself is tracked in FLINK-36659 (Resolved/Implemented,
fixVersion jdbc-4.0.0) and was published to Maven Central on 2025-04-17. In 4.0
users depend on the per-database module instead, e.g.
[flink-connector-jdbc-postgres:4.0.0-2.0|https://repo1.maven.org/maven2/org/apache/flink/flink-connector-jdbc-postgres/4.0.0-2.0/]
(which transitively pulls in {{{}-core{}}}).
||Artifact||3.3.0-1.20 (Flink 1.x)||4.0.0-2.0 (Flink 2.x)||
|{{flink-connector-jdbc}} (shaded uber-jar)|(/)|(x) removed|
|{{flink-connector-jdbc-core}}|(/)|(/)|
|{{flink-connector-jdbc-postgres}} / {{-mysql}} / {{-oracle}} / …|(/)|(/)|
So the Flink 2.x-compatible JDBC connector exists — just under the per-DB
coordinates rather than the old {{flink-connector-jdbc}} name.

> Compilation failure
> cannot access org.apache.flink.api.connector.sink2.StatefulSink [ERROR]
> class file for org.apache.flink.api.connector.sink2.StatefulSink not found
> {code}
> Possible reason: Many existing connectors (e.g., Kafka Connector 3.x) still
> reference {{{}StatefulSink{}}}, which was present in Flink 1.x but is being
> phased out or changed in 2.x.
