Plugin Maven and jdbc oracle

Hello everyone, i will start to say sorry for my bad english (if he is for you), but i will do my best.

So my problem is simple i think but i still need advice.
So i use the plugin Maven, everything work, it's launche my SoapUi projet during the test phase. But it doesn't launch JDBC test request and i don't know why.

Here the plugin call in the pom.xml :

<plugin>
    <groupId>eviware</groupId>
    <artifactId>maven-soapui-plugin</artifactId>
    <version>2.5.1</version>
    <configuration>
     <projectFile>${basedir}*********************************soapui-project.xml</projectFile>
     <printReport>true</printReport>
     <testSuite>TestSuiteWS</testSuite> 
     <outputFolder>${basedir}/target</outputFolder>
     <junitReport>true</junitReport>
     <exportAll>true</exportAll>
    </configuration>
    <executions>
     <execution>
      <phase>test</phase>
      <goals>
       <goal>test</goal>
      </goals>
     </execution>
    </executions>
   </plugin>

and i got that in my log :

soapUI 2.5.1 Maven2 TestCase Runner
10:32:09,930 WARN  [DefaultSoapUICore] Missing folder [D:*****************************************Appli_Blanche_Client_WS\.\ext] for external libraries
10:32:10,305 INFO  [DefaultSoapUICore] initialized soapui-settings from [D:***********soapui-settings.xml]
10:32:11,433 INFO  [WsdlProject] Loaded project from [file:/D:**************************Appli_Blanche_Client_WS/src/test/resources/********************soapui-project.xml]
10:32:11,615 ERROR [WsdlTestCase] Failed to create test step for [JDBC Request]

As you see he can't creat JDBC request whist is a simple select in the Oracle base. I guess i need some oracle driver but i don't know where put it and how add it in my pom.xml.

Help plz.


Ps : all ****** are normal i have to hide some information
