I'm trying to use the schemagen ant task from JAXB-RI 2.2.7, but I keep getting "BUILD FAILED .... Error starting ap" on the schemagen task in build.xml. The relevant stanzas are as follows:
<taskdef name="schemagen" classname="com.sun.tools.jxc.SchemaGenTask">
<classpath refid="compile.classpath"/>
</taskdef>
<target name="schemas" description="Compile all Java source files">
<mkdir dir="${schemas.dir}" />
<schemagen destdir="${schemas.dir}">
<src path="${src.dir}"/>
<classpath refid="compile.classpath" />
</schemagen>
</target>
With -verbose, I get the stack trace below. I've tried googling for the details of the ClassCastException but not found anything. Any suggestions?
Thanks, Adam
