I have been trying to execute mvn jaxws:wsimport by using the Maven JAX-WS plugin:

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>jaxws-maven-plugin</artifactId>
    <version>${maven.jaxws.plugin}</version>
    <executions>
        <execution>
            <goals>
                <goal>wsimport</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <sourceDestDir>generated-sources/jaxws-wsimport</sourceDestDir>
        <xnocompile>true</xnocompile>
        <verbose>true</verbose>
        <extension>true</extension>
        <sei>/</sei>
        <wsdlFiles>
            <wsdlFile>${basedir}/src/main/resources/wsdl/movieservice.wsdl</wsdlFile>
        </wsdlFiles>
    </configuration>
</plugin>


But I am getting the following error:

Caused by: java.lang.AssertionError: org.xml.sax.SAXParseException;
systemId: jar:file:/Users/mickknutson/.m2/repository/com/sun/xml/bind/jaxb-xjc/2.2.8-b01/jaxb-xjc-2.2.8-b01.jar!/com/sun/tools/xjc/reader/xmlschema/bindinfo/binding.xsd; 
lineNumber: 52; columnNumber: 88; 
schema_reference: Failed to read schema document 'xjc.xsd', 
because 'file' access is not allowed due to restriction set by the accessExternalSchema property.


Here is the full the error I am getting:

There have been plenty of talks about a resolution, but I solved the issue by adding
-Djavax.xml.accessExternalSchema=all as a system property.
