XJC generation error: Cannot parse number of arguments

I have the following error when trying to generate classes from my wsdl:

Failed to execute target org.jvnet.jaxb2.maven2: maven-jaxb2-plugin: 0.12.3: generate (CreateWebServiceAccountV1) in project hblws.test: execute CreateWebServiceAccountV1 target org.jvnet.jaxb2.maven2: maven-jaxb2-12 .3: generation failed: unable to parse argument number: '' http://java.sun.com/xml/ns/jaxb '': for input line: "'' http://java.sun.com/xml/ ns / jaxb '' "→ [Help 1]

I have one wsdl file and several XSD / XJBs. XJB has the following namespace: xmlns = "http://java.sun.com/xml/ns/jaxb"

Here is the pom.xml code that triggers the JAXB / XJC generation:

                </execution>
