NoSuchMethodException thrown with maven-jaxb2-plugin >= 0.12.2 and schema contains annotation

[lhanson]

With a relatively simple schema compilation project, using jaxb-xew-plugin:1.7 with any version of maven-jaxb2-plugin greater than 0.12.1 results in the following stacktrace:

[INFO] Sources are not up-to-date, XJC will be executed.

I've discovered that the error is triggered by the presence of an <xs:annotation> element.

Simplified example project: https://github.com/lhanson/jaxb-xew-plugin-50

[dmak]

It is actually resulted the fact that maven-jaxb2-plugin v0.12.2 depends on org.glassfish.jaxb:jaxb-core v2.2.11, while xew depends on com.sun.xml.bind:jaxb-core v2.2.7. I don't know why Glassfish team decided to clone JAXB with another Maven group and I can't judge if that was smart for jaxb2 plugin team to use that as dependency, but as a result Maven cannot manage this dependency correctly as they are two different libraries for Maven. Finally the classpath is a terrible mixup of two JAXB runtimes. The solution is to exclude the conflicting dependency:

<plugin>
    <groupId>org.jvnet.jaxb2.maven2</groupId>
    <artifactId>maven-jaxb2-plugin</artifactId>
    <version>0.12.2</version>
    <executions>
        ...
    </executions>
    <dependencies>
        <dependency>
            <groupId>com.github.jaxb-xew-plugin</groupId>
            <artifactId>jaxb-xew-plugin</artifactId>
            <version>1.7</version>
            <exclusions>
                <exclusion>
                    <groupId>com.sun.xml.bind</groupId>
                    <artifactId>jaxb-xjc</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
    </dependencies>
</plugin>

After that the project builds just fine.
