Hi,
I am trying to call an Ant build containing a EOL file programmatically.
My build.xml contains the following:
<project default="gen" name="Generate Data Configuration">
<!-- Get Classpath -->
<path id="project.class">
<pathelement location="lib/epsilon-1.5.1-kitchensink.jar"/>
</path>
<!-- Define Tasks -->
<taskdef name="epsilon.eol" classname="org.eclipse.epsilon.workflow.tasks.EolTask">
<classpath refid="project.class"/>
</taskdef>
<taskdef name="epsilon.emf.loadModel" classname="org.eclipse.epsilon.workflow.tasks.emf.LoadEmfModelTask">
<classpath refid="project.class"/>
</taskdef>
<!-- Define Targets -->
<target name="gen" description="Generate Data Configuration from abstract model">
<!-- Trace Rule Data Configuration -->
<epsilon.emf.loadModel name="abConfig"
read="true"
store="false"
metamodeluri="org.eclipse.capra.GenericDataConfigurationMetaModel"
modelfile="../Settings/abstract_data_config.ecore"
/>
<epsilon.emf.loadModel name="fullDataConfig"
read="false"
store="true"
metamodeluri="org.eclipse.capra.GenericDataConfigurationMetaModel"
modelfile="../06_Traceability/data_configuration.ecore"
/>
<!-- Generate Trace Data Configuration -->
<epsilon.eol src="src/generate_data_config.eol">
<model ref="abConfig"/>
<model ref="fullDataConfig"/>
</epsilon.eol>
</target>
...
</project>
If i try to run a ant build that runs a EOL file with no EMF models then i get no issues and the build completes successfully. However, if i try to run a EOL file with EMF Models referenced then the following ClassCastException is thrown.
java.lang.ClassCastException: class org.eclipse.epsilon.eol.models.ModelRepository cannot be cast to class org.eclipse.epsilon.eol.models.ModelRepository (org.eclipse.epsilon.eol.models.ModelRepository is in unnamed module of loader org.apache.tools.ant.AntClassLoader @332f6402; org.eclipse.epsilon.eol.models.ModelRepository is in unnamed module of loader org.apache.tools.ant.AntClassLoader @43ec687e)

I am running the following code to call the Ant build from Java:
File file = new File(buildFilePath);
Project project = new Project();
project.setBaseDir(new File(buildFilePath.substring(0, buildFilePath.lastIndexOf("/"))));
project.init();
DefaultLogger logger = new DefaultLogger();
logger.setErrorPrintStream(System.err);
logger.setOutputPrintStream(System.out);
logger.setMessageOutputLevel(Project.MSG_INFO);
project.setProperty("ant.file", file.getAbsolutePath());
project.addBuildListener(logger);
project.fireBuildStarted();
ProjectHelper helper = ProjectHelper.getProjectHelper();
project.addReference("ant.projectHelper", helper);
helper.parse(project, file);
if (targetToRun == null) {
project.executeTarget(project.getDefaultTarget());
} else {
project.executeTarget(targetToRun);
}
As you can see i am using the latest stable version of the Epsilon kitchensink. I have tried to use the latest interim version of the kitchen sink (Version 1.6.0) however, a NoClassDefFoundError is raised
java.lang.NoClassDefFoundError: org/antlr/runtime/TokenSource
Sorry for the long message.
Hope someone can help,
Thanks,
Charlie Parsons

Hi Charlie,
> When creating the minimal example the issue i am having doesn't occur and everything runs as expected, but within my main program i am still having this issue occur.
If we can't reproduce the error locally, it's unlikely that we'll be able to offer much assistance. I'd suggest starting with a copy of your full program, and removing one feature at a time, until the unwanted behaviour stops occurring.
Thanks,
Dimitris
