Hi, can you explain why want to change this?

When we pakcage manually, all jdbc driver jars will be put in lib/, every seatunnel job before start it will load all jars in lib, so if any jobs doesn't need these dependencies, it maybe casue jar conflict. This change only infect the package manually. e.g. : mvn clean package -Pci. But we have another concern about it because all ci steps do not be executed. This change whether infect the jdbc connectors we don't a clearly result.

so if any jobs doesn't need these dependencies, it maybe casue jar conflict

Seem this PR doesn't fix this error. All driver also would be loaded when submit a job if put it in plugin/lib.
