Hi Yuepeng, As Ferenc noted, Flink 1.20.0 was aged off the mirror after newer patches shipped, so the CI binary download 404s — and bumping to 1.20.5, as suggested, fixes it. I verified the full JDK 8/11/17/21 matrix green on a fork (runs/28815887503 <https://github.com/weiqingy/flink-connector-jdbc/actions/runs/28815887503>, and opened a PR <https://github.com/apache/flink-connector-jdbc/pull/203>).
