Maven dependency in zip format with classifier

Question

I am trying to import some schemas from a project which are in zip format. The name of the file is mySchema-1.0.32-schema.zip. My dependency looks like:

<dependency>
    <groupId>some.group.id</groupId>
    <artifactId>mySchema</artifactId>
    <version>${schema.version}</version>
    <classifier>schema</classifier>
    <type>zip</type>
</dependency>

But the dependency does not get imported. It is in my repo (I have checked), and I have the source dependency for the same project and it works just fine. Are my classifier and my type right? Is this the way to import a zip file?

EDIT:

I've found out that if I change the <classifier> to source it does import the sources, and if I change it to -schemas it spits out an error. Hence, the import seems to be working. And although I can't see it in my list of dependencies in IntelliJ IDEA, if I run mvn dependency:tree, it exists there: \- some.group.id:mySchema:zip:schema:1.0.32-SNAPSHOT:compile

It might be my unzipping that is not working:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-dependency-plugin</artifactId>
  <executions>
    <execution>
      <id>unpack</id>
      <phase>process-resources</phase>
      <goals>
        <goal>unpack</goal>
      </goals>
      <configuration>
        <artifactItems>
          <artifactItem>
            <groupId>some.group.id</groupId>
            <artifactId>mySchema</artifactId>
            <version>${schema.version}</version>
            <classifier>schema</classifier>
            <type>zip</type>
            <overWrite>false</overWrite>
            <outputDirectory>${basedir}/src/main/resources/json</outputDirectory>
          </artifactItem>
        </artifactItems>
      </configuration>
    </execution>
  </executions>
</plugin>

And just to clarify, my output directory exists.

Found the solution. Added this plugin under the <build> section:

<plugins>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <executions>
      <execution>
        <id>unpack-config</id>
        <phase>compile</phase>
        <goals><goal>unpack-dependencies</goal></goals>
        <configuration>
          <includeGroupIds>some.group.id</includeGroupIds>
          <includeArtifactIds>mySchema</includeArtifactIds>
          <includeClassifiers>schema</includeClassifiers>
          <outputDirectory>${project.build.directory}</outputDirectory>
        </configuration>
      </execution>
    </executions>
  </plugin>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <configuration>
      <additionalClasspathElements>
        <additionalClasspathElement>${project.build.directory}</additionalClasspathElement>
      </additionalClasspathElements>
    </configuration>
  </plugin>
</plugins>
