XJC episode with maven

问题

How can I generate an episode with maven? I now get an error message: an operand is missing (org.apache.cxf:cxf-xjc-plugin:2.4.0:xsdtojava:generate-sources:generate-sources)

Here my plugin:

<plugin>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-xjc-plugin</artifactId>
            <version>2.4.0</version>
            <configuration>
                <extensions>
                    <extension>org.apache.cxf.xjcplugins:cxf-xjc-dv:2.4.0</extension>
                </extensions>
            </configuration>
            <executions>
                <execution>
                    <id>generate-sources</id>
                    <phase>generate-sources</phase>
                    <goals>
                        <goal>xsdtojava</goal>
                    </goals>
                    <configuration>
                        <xsdOptions>
                            <xsdOption>
                                <extension>true</extension>
                                <xsd>my.xsd</xsd>
                                <packagename>mypackage</packagename>
                                 <extensionArgs>
                                  <arg>-episode</arg>
                                 </extensionArgs>
                            </xsdOption>
                        </xsdOptions>
                    </configuration>

                </execution>
                <execution>
                 <configuration>
                        <xsdOptions>
                 <xsdOption>
                        <extension>true</extension>
                          <xsd>my.xsd</xsd>
                        <extensionArgs>
                            <arg>-Xdv</arg>
                        </extensionArgs>
                    </xsdOption>
                        </xsdOptions>
                    </configuration>

                </execution>


            </executions>

Edit: Creation of the episode works fine. In another project the jar file containing the episode is given in though the episodes attribute. But I get an Exception: Error while parsing schema(s).Location [ file:/D:/workspace/XXX/src/test/resources/XXX.xsd{45,32}]. om.sun.istack.SAXParseException2: compiler was unable to honor this conversion customization. It is attached to a wrong place, or its inconsistent with other bindings. nested in com.sun.istack.SAXParseException2: (the above customization is attached to the following location in the schema)

Which is the xsd with episode info that will be included in the final product. Its some xjc:javaType adapter reference on that line. Can that cause problems?

Different plugin from what you're using, but below snipped used to work for me few years back. You might want to see if more recent version of plugin is available etc. Also tweak to use your schema and remove bindings customization if not needed.
