How to generate XSDs from java beans having java.time.LocalDate?

I'm trying to use jaxb2-maven-plugin to generate xsd from java beans.

But I constantly get the following error:

java.time.LocalDate is a non-static inner class, and JAXB can't handle those.
    this problem is related to the following location:
        at java.time.LocalDate (Unknown Source)

The bean is like:

public class MyBean {
    private LocalDate date;
}

I therefore created a jaxb mapping file and an adapter converting between java.time.LocalDate and xs:date. But the error just remains the same.

 public class LocalDateAdapter {
    private static DateTimeFormatter fmt = DateTimeFormat.forPattern("yyyyMMdd");

    public static LocalDate unmarshal(String v) throws Exception {
        return fmt.parseLocalDate(v);
    }

    public static String marshal(LocalDate v) throws Exception {
        return v.toString("yyyyMMdd");
    }
 }
