Add the dependency of the zip file like the following:
The following is an example for archive which has been created by maven-assembly-plugin:
<dependency>
<groupId>the.group.id</groupId>
<artifactId>the-artifactid</artifactId>
<version>1.0</version>
<type>tar.gz</type>
<cassifier>bin-unix</classifier>
</dependency>
<dependency>
<groupId>the.group.id</groupId>
<artifactId>the-artifactid</artifactId>
<version>1.0</version>
<type>zip</type>
<cassifier>bin</classifier>
</dependency>
The classifier in those cases is comming from the assembly-decscriptor-id in the project which creates the archive. Apart from that it is important to define the type.
