--------------------------------------
Summary: JDBC backwards compatibility workflow fails because Flink
2.0 and 2.1 SNAPSHOTs are no longer published
Key: FLINK-41454
URL: https://issues.apache.org/jira/browse/FLINK-41454
Project: Flink
Issue Type: Bug
Components: Connectors / JDBC
Affects Versions: jdbc-5.0.0, jdbc-4.1.1, jdbc-3.5.0
Reporter: Martijn Visser
Assignee: Martijn Visser
Fix For: jdbc-5.0.0
The "Flink Connector JDBC CI Backwards Compatibility" workflow fails on every
run since 2026-11-03, on main as well as on PRs:
https://github.com/apache/flink-connector-jdbc/actions/runs/43087647639/job/130756151967
{code}
[ERROR] Failed to execute goal on project flink-connector-jdbc-parent: Could
not resolve dependencies for project
org.apache.flink:flink-connector-jdbc-parent:pom:5.0-SNAPSHOT: The following
artifacts could not be resolved:
org.apache.flink:flink-connector-base:jar:2.0-SNAPSHOT, ...
{code}
2.0-SNAPSHOT and 2.1-SNAPSHOT are no longer in the Apache snapshot repository.
The v3.4 matrix (1.18-SNAPSHOT, 1.19-SNAPSHOT) has the same problem.
The module was added in FLINK-35370 to test the FLIP-449 package move. Since
4.0 the old packages are gone and the module's tests use the new API, so on
main and v4.1 we should remove the module and the workflow, and keep the
PostgreSQL JdbcSink tests by moving them to flink-connector-jdbc-postgres. On
v3.4 we should switch the matrix to released Flink versions.
