XSD2GenModel: set package name for java generated code [message #1857281]

Hi all,
I use org.eclipse.emf.codegen.ecore.XSD2GenModel application
(in headless mode) to create the genmodel and ecore files.
I would like to set the package name that will be used by the generated java code
How can I do? I cannot find any option in this application
(nor in the org.eclipse.emf.codegen.ecore.Generator application
I use afterwards to generate the javacode) to do that.
Thanks for your answers.
Thomas

Perhaps better to create the GenModel with the settings you want and reload it with the application...

In general, you can control settings of the GenModel via GenModel annotations on the Ecore model and you can control those annotations via annotations in the XSD, e.g., this on the xsd:schema element:

  xmlns:genmodel="http://www.eclipse.org/emf/2002/GenModel" 
  genmodel:basePackage="org.example"

That was exactly the kind of tip I was looking for, thanks!
Do you know where can I find the list of genmodel annotations
I can use in the xsd?

There is no list. But if you open any *.ecore, and on any object use New -> EAnnotation -> "GenModel", in the properties view you see all the possible properties you can set which is pretty much the names of the corresponding GenXyz's features. Changing the value will record it as an annotation and that shows the name you can use

I tested the genmodel:basePackage annotation in the xsd file but it does not seem to work.
It creates a eAnnotation tag in the ecore file, but it does not add the basePackage attribute in the genmodel file :-(

Are you creating a new *.genmodel during this process or updating an existing one? I do expect org.eclipse.emf.codegen.ecore.genmodel.impl.GenPackageImpl.initialize(EPackage) to set it if it's not already set:

  public void initialize(EPackage ePackage)
  {
    if (getPrefixGen() == null && ePackage.getName() != null)
    {
      setPrefix(capName(ePackage.getName()));
    }

    if (getBasePackageGen() == null && EcoreUtil.getAnnotation(ePackage, GenModelPackage.eNS_URI, "basePackage") != null)
    {
      setBasePackage(EcoreUtil.getAnnotation(ePackage, GenModelPackage.eNS_URI, "basePackage"));

I don't know what I did previously but now it's working. Maybe a typo...
Anyway, thank you very much for your help.
