-----------------------------------
Summary: cxf-codegen-plugin fails to generate code from wsdl and
binding file after update to 4.x: XPath evaluation results in empty target node
Key: CXF-9102

in it, bindings.xml file, and HelloWorld.wsdl

despite all configuration remains the same and corresponds the examples in the
docs: [https://cxf.apache.org/docs/maven-cxf-codegen-plugin-wsdl-to-java.html]
It also works with cxf 4.x when I comment the
{noformat}
<bindingFiles>
<bindingFile>${basedir}/src/main/resources/bindings.xml</bindingFile>
</bindingFiles>{noformat}
part in the plugin configuration.
I've debugged a bit and it seems that the XPath lookup for node
`wsdl:definitions/wsdl:portType[@name='HelloWorld']` is evaluated not through
HelloWorld.wsdl file, but through the bindings.xml itself.
