Unfortunately I really don't know much about how Ant works... But my
sense is that if you have an existing already populated *.genmodel then
it will have have all the project folders already specified and they'll
just work...
I found one script that looks like this, so maybe with some kind of
macro thingy you can specify some things only once...
<project default="codegen" basedir="..">
<dirname property="antfile.dir" file="${ant.file}"/>
<!-- Global properties -->
<property name="main.directory" location="${antfile.dir}/.."/>
<property name="output.directory" location="${main.directory}"/>
<property name="source.directory" value="src"/>
<property name="genJDKLevel" value="5.0"/>
<target name="codegen">
<!-- A macrodef makes it easier to generate code for multiple
models in one script. -->
<macrodef name="ecore2Java">
<attribute name="modelName"/>
<element name="settings"/>
<sequential>
<emf.Ecore2Java
model="${main.directory}/model/@{modelName}.ecore"
genModel="${output.directory}/emf/@{modelName}.genmodel"
modelProject="${output.directory}"
modelProjectFragmentPath="${source.directory}"
modelPluginID="@{modelName}.model"
copyright="This is my code."
jdkLevel="${genJDKLevel}">
<settings/>
</emf.Ecore2Java>
</sequential>
</macrodef>
<!-- Generating the code for the library model -->
<ecore2Java modelName="library">
<settings>
<arg line="-package http:///library.ecore org.examples
Library"/>
</settings>
</ecore2Java>
</target>
</project>

I think you'd need to use some kind of macro substitution in Ant itself.

I don't know about that.

The generator does not produce .project files. IProjects are only
created when you generate in the IDE the normal way.
