Cannot be cast to class because they are in unnamed module of loader 'app'
I'm trying to create a bean from sources that were generated by wsdl2java.
Every time I try to run my Spring Boot app, I get the following error:
Caused by: java.lang.ClassCastException: class org.apache.cxf.endpoint.ClientImpl cannot be cast to class com.xignite.services.XigniteCurrenciesSoap (org.apache.cxf.endpoint.ClientImpl and com.xignite.services.XigniteCurrenciesSoap are in unnamed module of loader 'app')
I'm not sure how exactly I'm to include generated sources in my main Spring Boot application as a module.
My directory structure is:
├── build
│ └── generatedsources
│ └── src
│ └── main
│ └── java
│ └── com
│ └── xignite
│ └── services
│
└── src
└── main
├── java
│ └── io
│ └── mateo
│ └── stackoverflow
│ └── soapconsumption
└── resources
└── wsdls

Answer
I had a similar case, and (as mentioned by @Holger in the comment) the module info in the message is simply misleading - this is an actual case of trying to cast something to something that doesn't match it.
In your case, ClientImpl simply is not a subtype of XigniteCurrenciesSoap.
