Ruby test with jenkins/maven/testLink - ruby

Question

I am using Jenkins, maven and testLink plug-in to do automation test.
I would like to execute ruby test with Jenkins and hook theim in testLink.
Here is my pom.xml :
<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/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
...

<dependencies>
<dependency>
<groupId>org.testng</groupId>
<artifactId>testng</artifactId>
<version>6.2.1</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.codeartisans</groupId>
<artifactId>ruby-maven-plugin</artifactId>
<version>0.1</version>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.codeartisans</groupId>
<artifactId>ruby-maven-plugin</artifactId>
<version>0.1</version>
<executions>

</goals>
<configuration>
<script>src/main/ruby/exec.rb</script>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
Here is my configuration in jenkins :
test Execution --> Single build steps --> Invoke top-level maven targets :
-->goals : -X
clean
org.codeartisans:ruby-maven-plugin:0.1:exec
test
-DsuiteXmlFiles=suite.xml
and here the console output :
These will use the artifact files already in the core ClassRealm instead, to allow them to be included in PluginDescriptor.getArtifacts().
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] One or more required plugin parameters are invalid/missing for 'ruby:exec'

</configuration>.
Could someone help me plz? I am new in maven, IC etc...
