maven package no jar without dependencies

Question

I managed to instruct maven to create a jar with all dependencies. When I run 'mvn package', it will produce two files: elvt-1.0.jar and elvt-1.0-jar-with-dependencies.jar.

However, I don't care for a jar without dependencies, and I would like the name of the jar with dependencies to be elvt-1.0.jar. I managed to do this by adding

<appendAssemblyId>false</appendAssemblyId>

to the configuration section of the maven-assembly-plugin artifact. This will produce two warnings however:

[WARNING] Configuration options: 'appendAssemblyId' is set to false, and 'classifier' is missing.
Instead of attaching the assembly file: /home/user/workspace/elvt/target/elvt-1.0.jar, it will become the file for main project artifact.
NOTE: If multiple descriptors or descriptor-formats are provided for this project, the value of this file will be non-deterministic!
[WARNING] Replacing pre-existing project main-artifact file: /home/user/workspace/elvt/target/elvt-1.0.jar
with assembly file: /home/user/workspace/elvt/target/elvt-1.0.jar

If I understand correctly, they both warn me about overwriting the jar without dependencies. How can I tell maven not to produce a jar without dependencies?

For reference purposes, this is what my pom.xml looks like:
