Hello friends

I'm trying to run an ant task from java emf for the generation of code and I get the following error

Exception: _C: \ ....... \ build.xml: 37: The following error occurred while executing this line:
C: \ ................ \ build.xml: 29: Problem: failed to create task or type emf.Ecore2Java
Cause: The name is undefined.
Action: Check the spelling.
Action: Check That any custom tasks / types Have Been Declared.
Action: Check That <presetdef> any / declarations have taken place <macrodef>.

Can you help me with this?

thanks

Again, I'm not expert at how to invoke Ant programmatically. I'm not
sure anyone on this forum is such an expert. Nor is it clear to me why
you need such a button. The ant task requires parameters you can more
easily configure in your GenModel and once you have a GenModel you can
easily generate from it. There's even Alt-Shift-G for generating all
models in your workspace.

HI

I'm not an expert either, although I have many scars to show for my
attempts.

Getting the ANT classpath right is really hard. Eclipse provides
integration for plugins but you're not really using a plugin since
you've contrived to have a custom classpath within a plugin classpath.
You therefore need at least to put the EMF ant tasks library on your
classpath.

Ed M recommends a GenModel, which is fine if a GenModel is enough.

I recommend an MWE script which gives you the power to sequence more
than just GenModel.

Regards
