Does a pom.xml.template tell me everything I need to know to use the project as a dependency

Question

I'm trying to add the lucene sandbox contribution called term-highlighter to my pom.xml. I'm not really that familiar with Maven, but the code has a pom.xml.template which seems to imply if I add a dependency that looks like:

<dependency>
  <groupId>org.apache.lucene</groupId>
  <artifactId>lucene-highlighter</artifactId>
</dependency>

It might work. Can someone help me out in adding a lucene-community project to my pom.xml file?

Thanks for the comments, it turns out that adding the version was all I needed, and I just guessed it should match the lucene-core version I was using.:

<dependency>
 <groupId>org.apache.lucene</groupId>
 <artifactId>lucene-highlighter</artifactId>
 <version>2.3.1</version>
</dependency>

You have it right, but you probably want to add the version as well:

From The Maven 5 minute tutorial

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"&gt;
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.mycompany.app</groupId>
  <artifactId>my-app</artifactId>
  <packaging>jar</packaging>
  <version>1.0-SNAPSHOT</version>
  <name>Maven Quick Start Archetype</name>
  <url>http://maven.apache.org&lt;/url&gt;

  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
  </dependencies>

</project>

You have to add the version number, but you only have to do it once in a project structure. That is, if the version number is defined in a parent pom, you don't have to give the version number again. (But you don't even have to provide the dependency in this case since the dependency will be inherited anyways.)
