Hey folks,
I'm trying right now to generate model java code from an ecore model and I'm able to du this with an ant task:
java -jar /Applications/eclipse/plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar -application org.eclipse.ant.core.antRunner -nosplash -buildfile build.xml
Ant task:
<?xml version="1.0" encoding="UTF-8"?>
<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}/ecore2java/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>
So now my question is, how to run this particular ant task from maven. Should I use pde-maven-plugin or can I use tycho-eclipserun-plugin, what is the best solution? I saw some similar topics in forum but no answer for this question.
Thanks for help,
Artem.

Yes, it generally won't generate one once it exists though in the latest
builds I've added support for merging of plugin.xml and MANIFEST.MF....

It seems to me there was some trick to let it know where the project
starts. Oh yes, hunting around I find
org.eclipse.emf.codegen.ecore.Generator.EclipseHelper.findOrCreateContainerHelper(String,
String, Monitor) where adding a "/./" in the path to indicate where the
project actually starts on the path. I also see that -projects would
help (point at the folder in which the , but I'm not sure how you
specify that in Ant.
public void printGenerateUsage()
{
System.out.println("Usage arguments:");
System.out.println(" [-projects <project-root-directory>]");
System.out.println(" [-dynamicTemplates] [-forceOverwrite | -diff]");
System.out.println(" [-generateSchema] [-nonNLSMarkers]");
System.out.println(" [-codeFormatting { default | <profile-file> }
]");
System.out.println(" [-model] [-edit] [-editor] [-tests]");
System.out.println(" [-autoBuild <true|false>]");
System.out.println(" [-reconcile]");
System.out.println(" <genmodel-file>");
System.out.println(" [ <target-root-directory> ]");
System.out.println("");
System.out.println("For example:");
System.out.println("");
System.out.println(" generate result/model/Extended.genmodel");
}
Can you run under debug control to see how best to take advantage of
these "tricks"?

Hi Ed,
thank you for your reply. I was able to solve my task partially. On your advise I've downloaded codegen.ecore' source and debugged Eclipse UI to find out, what happens by clicking "Generate Model code" and codegen.ecore.Generator by invoking it from command line. My task was to exclude artefacts, could be generated from ecore from version control: genmodel and generated models java code. Unfortunately I'm not able to exclude genmodel, only models java code. If I use ant task or org.eclipse.emf.importer.ecore.Ecore2GenModel to generate a genmodel from ecore I'm not able to specify a basePackage attribute of genmodel which than used by models code generation from this genmodel, so all the generated java classes get "package <prefix>;" in java source code. This is critical for me. But if I edit ecore in Eclipse UI, related genmodel gets updates automatically -- not such a big loss.
P.S.: Your book is great and very helpful!
