IntelliJ doesn't seem to know this is a Kotlin project.

IntelliJ 15.0.6 doesn't like the opening <project in the pom.xml. It says:

org/apache/maven/model/building/ModelSource2 less... (Ctrl+F1) 
Inspects a Maven model for resolution problems.
 org/apache/maven/model/building/ModelSource2

IntelliJ also complains about just about every Kotlin file with a little yellow "Kotlin not configured." bar at the top of the editor window. I checked that I have the Kotlin plugin installed and let the plugin configure Kotlin for the entire project. I think it threw this into the pom.xml file:

<plugin>
  <groupId>org.jetbrains.kotlin</groupId>
  <artifactId>kotlin-maven-plugin</artifactId>
  <version>${kotlin.version}</version>
  <executions>
    <execution>
      <id>compile</id>
      <phase>process-sources</phase>
      <goals>
        <goal>compile</goal>
      </goals>
      <configuration>
        <sourceDirs>
          <source>src/main/java</source>
        </sourceDirs>
      </configuration>
    </execution>
    <execution>
      <id>test-compile</id>
      <phase>process-test-sources</phase>
      <goals>
        <goal>test-compile</goal>
      </goals>
      <configuration>
        <sourceDirs>
          <source>src/test/java</source>
        </sourceDirs>
      </configuration>
    </execution>
  </executions>
</plugin>

But it's still not happy. I Invalidated Caches and Restarted, but no joy.
