jenkins build throwing error soapui 5.0.0

Hi All,

I am trying to build soapui testsuite from jenkins and my POM.xml has soapui repository details for version 5.0.0
When I am trying to build maven project, jenkins is throwing

WARNING: Failed to getClass for com.eviware.soapui.maven2.TestMojo

my POM has

<pluginRepositories>
<pluginRepository>
<id>SmartBearPluginRepository</id>
<url>http://www.soapui.org/repository/maven2/</url>
</pluginRepository>
</pluginRepositories>
<build>
<plugins>
<plugin>
<groupId>com.smartbear.soapui</groupId>
<artifactId>soapui-maven-plugin</artifactId>
<version>5.0.0</version>

why is jenkins trying to getClass for com.eviware.soapui.maven2.TestMojo ?
