Unable to create an executable jar using m2eclipse

I just started learning how to use m2eclipse. What I'm trying to do is make a very simple program (Hello, World) and turn it into an executable jar. The java code itself:

public class Speak {

/**
 * @param args
 */
public static void main(String[] args) {
    System.out.println("Meow!");
}

}

which works great as a Java application. Then I try to use Maven to create the program, which is what happens, but then when I try to run .jar, it says to me: “Could not load Main-Class attribute from ...”. This is the .pom that m2eclipse generates when the project starts:

<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">
<modelVersion>4.0.0</modelVersion>
<groupId>org.felines</groupId>
<artifactId>tabbies</artifactId>
<version>0.0</version>
<dependencies>
<dependency>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-jar-plugin</artifactId>
  <version>2.3.1</version>
  <type>maven-plugin</type>
  <scope>compile</scope>
</dependency>
</dependencies>
</project>

I tried modifying .pom, for example:

<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">
<modelVersion>4.0.0</modelVersion>
<groupId>org.felines</groupId>
<artifactId>tabbies</artifactId>
<version>0.0</version>
<build>
<plugins>
    <plugin>
        <artifactId>maven-jar-plugin</artifactId>
        <version>2.3.1</version>
        <configuration>
        <archive>
        <manifest>
             <mainClass>org.felines.Speak</mainClass>
             <packageName>org.felines</packageName>
        </manifest>
            <manifestEntries>
                <mode>development</mode>
                <url>${pom.url}</url>
        </manifestEntries>
        </archive>
        </configuration>
    </plugin>
</plugins>
</build>
</project>

Now he says: "Could not find the main class: org.felines.Speak. The program will exit." Any ideas?: (

Thank you for your time!
