Running an error after the project is packaged

The project runs normally in eclipse, but there is a problem when the project is packaged and runs in the terminal. How should this problem be solved?

Drools doesn't like uber-jarring because several jars have a META-INF directory with files with the same name. So last-one-wins.

Either don't use uber-jarring or doing use Drools score calculation.
