xjc fails to generate classes when using bindings

Question

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 ]

Answer 1

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

Answer 2

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.
