Hi,

I need some help Discovering Model and Generating Code programmatically in Modisco 0.9!

In Modisco 0.8 was using those two methods to do my job:

public void modelDiscovery(String projectName, String savePath){
		try {
			IProject project = 
				ResourcesPlugin.getWorkspace().getRoot().getProject(projectName);
			IJavaProject javaProject = JavaCore.create(project);
			DiscoverJavaModelFromJavaProject javaDiscoverer = new DiscoverJavaModelFromJavaProject();
			Map<DiscoveryParameter, Object> parameters = new HashMap<DiscoveryParameter, Object>();
			parameters.put(DefaultDiscoverer.PARAMETER_SILENT_MODE, true);
			javaDiscoverer.discoverElement(javaProject, parameters);
			//Resource output = (Resource) parameters.get(DefaultDiscoverer.PARAMETER_TARGET_RESOURCE);
			//Tools.saveModel(output, savePath);
		} catch (Exception e) {
			System.err.println("Error: " + e.getMessage());
		}
	}

public void generateJava(String javaModelFilepath, String generatedCodeFolderPath){
		Generate_JavaStructures javaGenerator = null;
		
		try {
			javaGenerator = new Generate_JavaStructures(URI.createFileURI(javaModelFilepath),
					new File(generatedCodeFolderPath),
					//new File(""),
					new ArrayList<Object>());
			javaGenerator.doGenerate(null);
		} catch (IOException e) {
			e.printStackTrace();
		}
	}

But in Modisco 0.9 are not working any more...
Is there anyone can help me?

Thanks
Thanasis

Hi me

,

I've found it!

Model Discovery:

Adding to manifest

Require-Bundle:
 org.eclipse.gmt.modisco.java;bundle-version="0.9.0",
 org.eclipse.modisco.java.discoverer;bundle-version="0.9.0",
 org.eclipse.modisco.infra.discovery.core;bundle-version="0.9.0",

public void modelDiscovery(String projectName, String savePath){
		try {
			IProject project = 
				ResourcesPlugin.getWorkspace().getRoot().getProject(projectName);
			IJavaProject javaProject = JavaCore.create(project);
			DiscoverJavaModelFromJavaProject javaDiscoverer = new DiscoverJavaModelFromJavaProject();
			javaDiscoverer.discoverElement(javaProject, new NullProgressMonitor());
			Resource javaResource = javaDiscoverer.getTargetModel();
			FileOutputStream fout = new FileOutputStream(new File(savePath));
			javaResource.save(fout, null);
			fout.close();

		} catch (Exception e) {
			System.err.println("Error: " + e.getMessage());
		}
	}

Code Generation:

Adding to manifest

Import-Package:
 org.eclipse.gmt.modisco.java.generation.files,
 org.eclipse.acceleo.engine.service,

public void generateJava(String javaModelFilepath, String generatedCodeFolderPath){
		try {
			GenerateJavaExtended javaGenerator = new GenerateJavaExtended(URI.createFileURI(javaModelFilepath),
					new File(generatedCodeFolderPath),
					new ArrayList<Object>());
			javaGenerator.doGenerate(null);
		} catch (IOException e) {
			e.printStackTrace();
		}
	}

Hi,

thanks for your interest in our MoDisco components. We're glad you made it work with new 0.9 API.
However, we are curious to understand what problems you encountered with old API. It has been deprecated but we tried to maintain its good working : for instance the JUNIT test org.eclipse.gmt.modisco.java.discoverer.tests.SimpleBlackBoxDiscovery.testJavaModelDiscoveryFromJavaProject() makes nearly the same invocation of oegm.DiscoverJavaModelFromJavaProject class as you have done.

Is it possible for you to explain which kind of problem you had (compilation, errors at execution, ...) ?

Fabien.

Hi,
I didn't have any problem with the previous version, everything was working as a charm... I've just changed my code because as you said the old methods are deprecated...
