Ensure documentation examples are tested

[DiesDasJenes]

Aloha,

i've found a mismatch in the documentation between the kotlin examples. I tried the kotlin examples in gradle 6.7 and had to change the code.

In the chapter "3. Generating Java Sources" under section 3.1 the kotlin code example should look like this:

cxfCodegen {
    wsdl2java.create("example") {
        wsdl.set(file("path/to/example.wsdl"))
        markGenerated.set(true)
    }
}

Similar with 3.2:

cxfCodegen {
    wsdl2java.create("example") {
            wsdl.set(file("path/to/example.wsdl"))
            outputDir.set(file("$buildDir/generated-java")) 
            markGenerated.set(true) 
            packageNames.set(listOf("com.example", "com.foo.bar")) 
            asyncMethods.set(listOf("foo", "bar")) 
        }
    }
}

I don't know how 3.3 needs to look like. Great plugin btw :) I hope my proposal will help newbies like me with their gradle setup.

Thanks for raising the issue. Similar to https://github.com/ciscoo/cxf-codegen-gradle/issues/3.

I will need to ensure that the examples in the documentation are valid and tested. I also think it may be related to the way the container is defined in CxfCodegenExtension.

Repurposing this issue to tackle testing examples in documentation.
