xjc fails to generate classes when using bindings

This used to work with all previous versions of JAXB. I've upgraded to version 2.2.7 of JAXB and now xjc throws the following:

java.lang.AssertionError: javax.xml.bind.JAXBException - with linked exception: [com.sun.xml.internal.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
com.sun.xml.bind.api.impl.NameConverter is an interface, and JAXB can't handle interfaces. this problem is related to the following location: at com.sun.xml.bind.api.impl.NameConverter at public com.sun.xml.bind.api.impl.NameConverter com.sun.tools.xjc.reader.xmlschema.bindinfo.BIGlobalBinding.nameConverter at com.sun.tools.xjc.reader.xmlschema.bindinfo.BIGlobalBinding ]

As the whole JAXB project now moved from https://github.com/javaee/jaxb-v2 to https://github.com/eclipse-ee4j/jaxb-ri including the Maven dependencies, I updated my pom.xml from 

    <dependency>
        <groupId>com.sun.xml.bind</groupId>
        <artifactId>jaxb-xjc</artifactId>
        <version>${jaxb-xjc.version}</version>
    </dependency>

    <dependency>
        <groupId>com.sun.xml.bind</groupId>
        <artifactId>jaxb-core</artifactId>
        <version>${jaxb.version}</version>
    </dependency>

to 

    <dependency>
        <groupId>org.glassfish.jaxb</groupId>
        <artifactId>jaxb-xjc</artifactId>
        <version>${jaxb-xjc.version}</version>
    </dependency>

    <dependency>
        <groupId>org.glassfish.jaxb</groupId>
        <artifactId>jaxb-core</artifactId>
        <version>${jaxb.version}</version>
    </dependency>

This helped me at least with a similar issue.

Assumed that you are using Eclipse or a derivative (websphere studio, jDeveloper, Spring Tools Suite, ...). If not, you may use the JDK 'xjc' command line tool, else the Maven Plug-in JAXB2)

You have to explicitly configure JAXB for the project (different projects may bear different configs to make things simple!)

In recent Eclipse version (4.4+) follow these steps:

  • ensure the Eclipse Web Tools platform is installed in Eclipse
  • apply the JAXB facet to your Eclipse project containing the .xsd schemas to transform into jaxb classes; right-click project > properties > Project Facets > JAXB; further configuration is available and lets you select which library supplies the JAXB implementation (recent JRE has it) as well as the JAXB version. > OK > Apply.
  • select the .xsd file at stake, right-click > generate > JAXB classes ... at minimum supply a package name (e.g. draw it from the XSD namespace) > Finish
  • the Eclipse console view provides feedback on generated files

As of jaxb 2.2.7 they have split the jaxb libraries into several components. xjc is now decoupled from any particular jaxb runtime. To fix this issue, ensure a jaxb runtime is made available on the classpath when executing xjc. Details can be found on their release notes here: https://jaxb.java.net/nonav/2.2.7/docs/release-documentation.html#a-2-2-7

The reference implementation can be found on maven central with the following coordinate: com.sun.xml.bind:jaxb-impl:2.2.7
