java - JAXB schemagen doesn't reference classes in episode file -

i using schema first approach, hit roadblock "ominous" jaxb map problem! , worked around switching code first approach one. i'd reuse type in other modules , continue schema first approach creating episode file generated schema. unfortunately generated episode file empty. here tried:

<plugin>     <groupid>org.codehaus.mojo</groupid>     <artifactid>jaxb2-maven-plugin</artifactid>     <version>2.2</version>     <executions>         <execution>             <id>schemagen</id>             <goals>                 <goal>schemagen</goal>             </goals>             <phase>generate-sources</phase>         </execution>     </executions>     <configuration>         <outputdirectory>${project.build.outputdirectory}</outputdirectory>         <generateepisode>true</generateepisode>         <transformschemas>             <transformschema>                 <uri>http://some/schema/types</uri>                 <toprefix>core</toprefix>                 <tofile>core-types.xsd</tofile>             </transformschema>         </transformschemas>     </configuration> </plugin> 

this generated me following schema:

<?xml version="1.0" encoding="utf-8" standalone="yes"?> <xs:schema xmlns:xs="http://www.w3.org/2001/xmlschema" xmlns:core="http://some/schema/types" targetnamespace="http://some/schema/types" version="1.0">   <xs:element name="map" type="core:maptype"/>    <xs:complextype name="maptype">     <xs:sequence>       <xs:element maxoccurs="unbounded" minoccurs="0" name="entries" nillable="true" type="core:entrytype"/>     </xs:sequence>   </xs:complextype>    <xs:complextype name="entrytype">     <xs:sequence>       <xs:element name="key" type="xs:anytype"/>       <xs:element name="value" type="xs:anytype"/>     </xs:sequence>   </xs:complextype> </xs:schema> 

and episode file content:

<?xml version="1.0" encoding="utf-8" standalone="yes"?> <ns1:bindings version="2.1" xmlns:ns1="http://java.sun.com/xml/ns/jaxb"/> 

i tried use schemagen standalone (version 2.2.11) similar results. documentation @ https://jaxb.java.net/2.2.4/docs/schemagen.html , http://www.mojohaus.org/jaxb2-maven-plugin/documentation/v2.2/schemagen-mojo.html seams indicate should it, can't figure out doing wrong.

i resolve problem... follow above:

    <plugin>                     <groupid>org.codehaus.mojo</groupid>                     <artifactid>jaxb2-maven-plugin</artifactid>                     <version>1.6</version>                     <executions>                         <execution>                             <id>schemagen</id>                             <goals>                                 <goal>schemagen</goal>                             </goals>                             **<phase>generate-sources</phase>**                         </execution>                     </executions>                      <configuration>                                   **<xsdpathwithinartifact>generated/xsds</xsdpathwithinartifact>**  </configuration>       </plugin>
