Kotlin: Unresolved reference: jetbrains

Hello,

I'm attempting to build a Spek "specification" for a Kotlin class that I wrote. The project uses maven and has the correct folder structure ('src/main/kotlin' and 'src/main/test/kotlin'). My pom.xml file has the following dependencies:

<dependencies>
    <dependency>
        <groupId>org.jetbrains.kotlin</groupId>
        <artifactId>kotlin-stdlib-jdk8</artifactId>
        <version>${kotlin.version}</version>
    </dependency>

   <!-- https://mvnrepository.com/artifact/org.jetbrains.spek/spek-api -->
   <dependency>
      <groupId>org.jetbrains.spek</groupId>
      <artifactId>spek-api</artifactId>
      <version>1.1.5</version>
      <scope>test</scope>
   </dependency>

   <!-- https://mvnrepository.com/artifact/org.jetbrains.spek/spek-junit-platform-engine -->
   <dependency>
      <groupId>org.jetbrains.spek</groupId>
      <artifactId>spek-junit-platform-engine</artifactId>
      <version>1.1.5</version>
      <scope>test</scope>
   </dependency>

  <dependency>
      <groupId>org.jetbrains.kotlin</groupId>
      <artifactId>kotlin-reflect</artifactId>
      <version>${kotlin.version}</version>
      <scope>test</scope>
   </dependency>

</dependencies>

I also have the Spek plugin installed in IntelliJ.

When I attempt to run my Spek class, I recieve the error "Kotlin: Unresolved reference: jetbrains".

Please help!
