We've downloaded uber jar 6.2.0 from AEM Support portal and it has parent project:
<parent> <groupId>com.day.cq</groupId> <artifactId>parent</artifactId> <version>48</version> </parent>
In public AEM repo I see only version 40. https://repo.adobe.com/nexus/content/repositories/releases/com/day/cq/parent/
Where we can find version 48?
Pls don't download the JAR in that way. You just need to include dependency in parent POM.
