How to generate maven jar that will include my external jars that under lib folder

Question

I have maven project with lib folder that contains some jars, In my pom.xml, I've added dependency accordingly like:

<dependency>
    <groupId>autoit</groupId>
    <artifactId>autoit</artifactId>
    <version>1.0</version>
    <scope>system</scope>
    <systemPath>${basedir}/lib/AutoItX4Java.jar</systemPath>
</dependency>

The problem is when I create a jar and run on cmd I get Exception:

nested exception is: java.lang.NoClassDefFoundError : AutoItX4Java...

If I run via eclipse there are no Errors.
