=== Copying dependency JARs to a specific directory

You can use the `camel dependency copy` command to copy the required JARs to a specific folder.
This command reuses Maven by invoking the `mvn dependency:copy-dependencies` command.

IMPORTANT: The `camel dependency copy` and `camel dependency list` uses Apache Maven,
This requires having Apache Maven installed, and `mvn` command in PATH environment, so Camel JBang
