WsdlProject(); cannot be cast to com.eviware.soapui.config.DefaultEndpointStrategyConfig

TL:DR => WsdlProject project = new WsdlProject();

throws

Exception in thread "main" java.lang.ClassCastException: com.eviware.soapui.config.impl.EndpointStrategyConfigImpl cannot be cast to com.eviware.soapui.config.DefaultEndpointStrategyConfig

Hello, sorry for long post, but I did really tried to solve this on my own and I couldn't.

I am learning how to use SOAP request. And for this I am using SoapUI 5.6 (Free version) and testing the free wsdl API: http://webservices.oorsprong.org/websamples.countryinfo/CountryInfoService.wso?WSDL

From the SoapUI 5.6 I have successful sending of requests and receiving responses. But I want to do that "wit Java from IntelliJ".

My task is to use com.eviware.soapui.impl.wsdl.WsdlProject.class I have read quite a few tutorials and solved a few errors. The current error that I have though, I cannot solve. It is as follows:

13:01:59,689 INFO [PluginManager] 0 plugins loaded in 1 ms 13:01:59,689 INFO [DefaultSoapUICore] All plugins loaded Exception in thread "main" java.lang.ClassCastException: com.eviware.soapui.config.impl.EndpointStrategyConfigImpl cannot be cast to com.eviware.soapui.config.DefaultEndpointStrategyConfig

I have followed this topic NoClassDefFoundError com/eviware/soapui/impl/wsdl/WsdlProject

And I have created my initial code

String endPointUrl = "http://webservices.oorsprong.org/websamples.countryinfo/CountryInfoService.wso?WSDL"; WsdlProject project = new WsdlProject(); WsdlInterface[] wsdls = WsdlImporter.importWsdl(project, endPointUrl); WsdlInterface wsdl = wsdls[0];

The error is thrown when trying to create empty WsdlProject object.

From a comment in the thread above I see that I have to implement some dependancies which as 2016 were obviously accecable but not today. So I read that I have to use foreign repository which I have added to my pom.xml file:

<repositories>
    <repository>
        <id>smartbear</id>
        <name>smartbear repository</name>
        <url>http://smartbearsoftware.com/repository/maven2</url>
    </repository>
</repositories>

And I have added dependency

<dependency>
    <groupId>com.smartbear.soapui</groupId>
    <artifactId>soapui</artifactId>
    <version>5.2.1</version>
    <scope>test</scope>
</dependency>

Which is now synced and I am able to import

com.eviware.soapui.impl.wsdl.*

I am sorry but I cannot seem to solve this issue:

Exception in thread "main" java.lang.ClassCastException: com.eviware.soapui.config.impl.EndpointStrategyConfigImpl cannot be cast to com.eviware.soapui.config.DefaultEndpointStrategyConfig

Any idea what could cause it?
