IOutputConfigurationProvider Binding-Problem [message #1128223] Mon, 07 October 2013 13:20 Go to next message

Hi,

I follwed the following link to bind another output-dir for my generated files:
http://stackoverflow.com/questions/10350022/how-to-add-multiple-outlets-for-generated-xtext-dsl

If I clean my model and start a buildAll, this binding works fine.
If I start my generator via a generration-handler (see http://christiandietrich.wordpress.com/2011/10/15/xtext-calling-the-generator-from-a-context-menu/) only the default-OutputConfiguration is available. So in the EclipseResourceFileSystemAccess an Exception occurs.

I use Xtext 2.4.3 with Eclipse Kepler.

Has somebody an idea to fix the probelm?

What happens exactly. Name sure you add the binding to the uimodule.
Make sure you make a binding that fits to what you inject into the
handler

I added the binding to the UI module (with cleanAll - buildAll the functionality works fine).

I think it is something wrong with my generation handler. If I start the generator from my context-menue I get the Exception:
java.lang.RuntimeException: IContainer P/null does not exist


These are my injections in the handler and the generator-call:
public class GenerationHandler extends AbstractHandler implements IHandler {
@Inject
private IGenerator oGenerator;
@Inject
private Provider<EclipseResourceFileSystemAccess> oFileAccessProvider;
@Inject
IResourceDescriptions oRresourceDescriptions;
@Inject
IResourceSetProvider oResourceSetProvider;
@Override
public Object execute(ExecutionEvent oEvent) throws ExecutionException {
...
final EclipseResourceFileSystemAccess oFsa = oFileAccessProvider.get();
URI oUri = URI.createPlatformResourceURI(oFile.getFullPath().toString(), true);
ResourceSet oResourceSet = oResourceSetProvider.get(oProject);
Resource oResource = oResourceSet.getResource(oUri, true);
oGenerator.doGenerate(oResource, oFsa);

My OutputConfiguration:
public class WorkflowOutputConfigurationProvider implements IOutputConfigurationProvider {

public final static String s_sDEFAULT_OUTPUT_ONCE = "DEFAULT_OUTPUT_ONCE";
public final static String s_sDEFAULT_OUTPUT_FOLDER = "/src/configuration";

@Override
public Set<OutputConfiguration> getOutputConfigurations() {
Set<OutputConfiguration> oOutputConfig = new HashSet<OutputConfiguration>();

OutputConfiguration oDefaultOutput = new OutputConfiguration(IFileSystemAccess.DEFAULT_OUTPUT);
oDefaultOutput.setDescription("Output Folder");
oDefaultOutput.setOutputDirectory("./src-gen");
oDefaultOutput.setOverrideExistingResources(true);
oDefaultOutput.setCreateOutputDirectory(true);
oDefaultOutput.setCleanUpDerivedResources(true);
oDefaultOutput.setSetDerivedProperty(true);
oOutputConfig.add(oDefaultOutput);

OutputConfiguration oOnceOutput = new OutputConfiguration(s_sDEFAULT_OUTPUT_ONCE);
oOnceOutput.setDescription("Output Folder (once)");
oOnceOutput.setOutputDirectory("." + s_sDEFAULT_OUTPUT_FOLDER);
oOnceOutput.setOverrideExistingResources(false);
oOnceOutput.setCreateOutputDirectory(true);
oOnceOutput.setCleanUpDerivedResources(false);
oOnceOutput.setSetDerivedProperty(true);
oOutputConfig.add(oOnceOutput);

return oOutputConfig;
}
}

I tried two two Ways to bind the configuration in the ui-module (the fist one as comment):
// @Override
// public void configure(Binder binder) {
// super.configure(binder);
// binder.bind(IOutputConfigurationProvider.class).to(WorkflowOutputConfigurationProvider.class).in(Singleton.class);
// }

public Class<? extends IOutputConfigurationProvider> bindIOutputConfigurationProvider() {
return WorkflowOutputConfigurationProvider.class;
}

Are you sure your provider is not called?

p.S: do you have a complete stacktrace?

btw having a look at the code it seems like the builder uses org.eclipse.xtext.builder.EclipseOutputConfigurationProvider in the shared module.

The provider is called if I start a new eclipse-application to use the dsl-editor.
If I call the generator from context menue the provider is not invoked.

Sure you generate to an existing project?

Yes, the Generation works fine, if I start the new eclipse-application to use the dsl-editor. The build starts, the provider is called and the generated code is in the right folder.
Only calling the generator from contextmenue does not work.

Hi you have to link access and config yourself. Calling
FSA.setoutputpath is no longer sufficient.

Have a look at other calls of setoutputconfigs

The last version I tried.
The Provider works fine with cleanAll buildAll.
Calling the generator from context menue works not furthermore.
- I had problems with the path. So I implemented getOutputConfigurationsFromContext(). This fixed my path-problem.
- Another problem is, that the generation with oFsa overrides the already generated files. That's not what I want and not what I had configured (see OutputConfiguration(s_sDEFAULT_OUTPUT_ONCE))

Du to the fact that the functionality works fine with cleanAll buildAll it must be a problem in my Handler.
The Method getOutputConfigurations must be correct.

I use the deprecated EclipseResourceFileSystemAccess, but EclipseResourceFileSystemAccess2 don't work too Sad (see commented lines NullProgressMonitor and getWorkflowProject).


private EclipseResourceFileSystemAccess createFileSystemAccess(
WorkflowOutputConfigurationProvider oOutputConfigurationProvider) {
final EclipseResourceFileSystemAccess oFsa = oFileAccessProvider.get();
// oFsa.setMonitor(new NullProgressMonitor());
// oFsa.setProject(getWorkflowProject());
Map<String, OutputConfiguration> oOutputs = uniqueIndex(oOutputConfigurationProvider.getOutputConfigurationsFromContext(), new Function<OutputConfiguration, String>() {
public String apply(OutputConfiguration from) {
return from.getName();
}
});
oFsa.setOutputConfigurations(oOutputs);
...
oGenerator.doGenerate(oResource, oFsa);


From my Provider:
public final static String s_sDEFAULT_OUTPUT_ONCE = "DEFAULT_OUTPUT_ONCE";
public final static String s_sDEFAULT_OUTPUT_FOLDER = "/src/_Configuration";

@Override
public Set<OutputConfiguration> getOutputConfigurations() {
Set<OutputConfiguration> oOutputConfig = new HashSet<OutputConfiguration>();

OutputConfiguration oDefaultOutput = new OutputConfiguration(IFileSystemAccess.DEFAULT_OUTPUT);
oDefaultOutput.setDescription("Output Folder");
oDefaultOutput.setOutputDirectory("./src-gen");
oDefaultOutput.setOverrideExistingResources(true);
oDefaultOutput.setCreateOutputDirectory(true);
oDefaultOutput.setCleanUpDerivedResources(true);
oDefaultOutput.setSetDerivedProperty(true);
oOutputConfig.add(oDefaultOutput);

OutputConfiguration oOnceOutput = new OutputConfiguration(s_sDEFAULT_OUTPUT_ONCE);
oOnceOutput.setDescription("Output Folder (once)");
oOnceOutput.setOutputDirectory("." + s_sDEFAULT_OUTPUT_FOLDER);
oOnceOutput.setOverrideExistingResources(false);
oOnceOutput.setCreateOutputDirectory(true);
oOnceOutput.setCleanUpDerivedResources(false);
oOnceOutput.setSetDerivedProperty(true);
oOutputConfig.add(oOnceOutput);

return oOutputConfig;
}

//TODO Patch
public Set<OutputConfiguration> getOutputConfigurationsFromContext() {
Set<OutputConfiguration> oOutputConfig = getOutputConfigurations();
Iterator<OutputConfiguration> oIter = oOutputConfig.iterator();
while (oIter.hasNext()) {
OutputConfiguration oOutput = oIter.next();
if (s_sDEFAULT_OUTPUT_ONCE.equals(oOutput.getName())) {
oOutput.setOutputDirectory("./model-workflow" + s_sDEFAULT_OUTPUT_FOLDER);
return oOutputConfig;
}
}
return oOutputConfig;
}

Still The question: debugging The code: what happens in the access?
Does it get the information from the config? Does it use it at all?
Please have a look at the code (I have no eclipse with me so that I
can't)

Good Morning,
now I fixed it. The Problem was that I used:
IWorkspace oWorkspace = ResourcesPlugin.getWorkspace();
IWorkspaceRoot oRoot = oWorkspace.getRoot();
IProject oProject = oRoot.getProject("model-project");

instead of:
IProject oProject = oFile.getProject() from the Example mentioned above.

That caused my path-problems and the ignored configurations.

Sorry for any inconvenience...
