OK, i have committed the modifiactions i made to the xmlcodegen plugin to allow it to generate the schema for gml. But there is a disclaimer, i had to hack the gml schema files to do it.
I have attached some relevant files here: http://jira.codehaus.org/browse/GEOT-2505 Including: 1) the generated GMLSchema (which does not compile) 2) the patches to the gml xsd 3) the xsd-gml3 pom.xml plugin configuration I have also updated some of the docs here: http://docs.codehaus.org/display/GEOTDOC/1+Configuration+Parameter+Reference So to reproduce what i have done you should: 1) build the xmlcodegen plugin locally 2) apply the patches to the gml schema 3) set up teh plugin configuration And then from the xsd-gml3 module: mvn org.geotools.maven:xmlcodegen:generateSchema The generated schema will end up in src/main/java -Justin Justin Deoliveira wrote: > Hi Ben, > > I will throw this on my todo list for tomorrow.
