Add a jar file to depedencies in a Maven in NetBeans

I have a local just and I want to add it to dependencies of a Maven.

I try to things work according to this

My file is somewhere locally so I use this in the pom.xml file:

<dependency>
    <groupId>opt</groupId>
    <artifactId>Copt</artifactId>
    <version>1.4</version>
    <scope>compile</scope>
    <systemPath>$C:Usersaiafilesexample.jar</systemPath>
</dependency>

What is the right way to right the systemPath?
