I finally found it. The class is in gt-xsd-core.jar
. The required maven dependency is
<dependency>
<groupId>org.geotools.xsd</groupId>
<artifactId>gt-xsd-core</artifactId>
<version>9.3</version>
</dependency>
I also needed the KMLConfiguration
class, which I found in gt-xsd-kml.jar
. The required dependency is
<dependency>
<groupId>org.geotools.xsd</groupId>
<artifactId>gt-xsd-kml</artifactId>
<version>9.3</version>
</dependency>
