I have a quite large grammar.
When I generate the Xtext Artifacts, many many java classes are generated. Generators run successfully. However, almost always some of the classes which are generated have random mistakes in them, which makes them unable to compile.
It is usually only one or two .java classes among almost a hundred which have mistakes, and it is not the same classes, the mistakes seem to come randomly.
Bit it is usually inside the the package implementation class.
Here is an example mistake:
public EClass getActionDeclaration()
{
if (actionDeclarationEClass == null)
{
actionDeclarationEClass = (EClass)EPackage.Registry.INSTANCE.getEPackage(HmiPackage.eNS_URI).getEClassifiers().g(96);
}
return compositeActionEClass;
}
this code should actually look like this:
public EClass getActionDeclaration()
{
if (actionDeclarationEClass == null)
{
actionDeclarationEClass = (EClass)EPackage.Registry.INSTANCE.getEPackage(HmiPackage.eNS_URI).getEClassifiers().get(92);
}
return actionDeclarationEClass;
}
so the instead of "get" there is "g"
Here is my Workflow, if that helps:
module de.bmw.rhmi.GenerateHmi
import org.eclipse.xtext.xtext.generator.*
import org.eclipse.xtext.xtext.generator.model.project.*
import org.eclipse.emf.mwe.utils.*
var rootPath = ".."
var projectName = "de.bmw.rhmi"
var runtimeProject = "../${projectName}"
Workflow {
bean = StandaloneSetup {
scanClassPath = true
platformUri = "${rootPath}"
registerGenModelFile = "platform:/resource/de.bmw.rhmi.resource/model/generated/Strings.genmodel"
registerGenModelFile = "platform:/resource/de.bmw.rhmi.resource/model/Image.genmodel"
registerGenModelFile = "platform:/resource/de.bmw.rhmi/model/generated/App.genmodel"
registerGenModelFile = "platform:/resource/de.bmw.rhmi/model/generated/Hmi.genmodel"
registerGeneratedEPackage = "de.bmw.rhmi.resource.image.ImagePackage"
registerGeneratedEPackage = "de.bmw.rhmi.resource.strings.StringsPackage"
}
component = XtextGenerator {
configuration = {
project = StandardProjectConfig {
baseName = "de.bmw.rhmi"
rootPath = rootPath
runtimeTest = {
enabled = true
}
genericIde = {
enabled = true
}
mavenLayout = true
}
code = {
encoding = "UTF-8"
lineDelimiter = "\n"
fileHeader = "/*\n * generated by Xtext \${version}\n */"
}
}
language = XtextGeneratorLanguage {
name = "de.bmw.rhmi.App"
fileExtensions = "rapp"
referencedResource = "platform:/resource/org.eclipse.xtext.xbase/model/Xbase.genmodel"
fragment = grammarAccess.GrammarAccessFragment2 {}
fragment = ecore.EMFGeneratorFragment2 {}
fragment = serializer.SerializerFragment2 {}
fragment = resourceFactory.ResourceFactoryFragment2 {}
fragment = parser.antlr.XtextAntlrGeneratorFragment2 {}
fragment = validation.ValidatorFragment2 {}
fragment = scoping.ImportNamespacesScopingFragment2 {}
fragment = exporting.QualifiedNamesFragment2 {}
fragment = builder.BuilderIntegrationFragment2 {}
fragment = formatting.Formatter2Fragment2 {}
fragment = ui.labeling.LabelProviderFragment2 {}
fragment = ui.outline.QuickOutlineFragment2 {}
fragment = ui.outline.OutlineTreeProviderFragment2 {}
fragment = ui.quickfix.QuickfixProviderFragment2 {}
fragment = ui.contentAssist.ContentAssistFragment2 {}
fragment = junit.JUnitFragment {}
fragment = ui.refactoring.RefactorElementNameFragment2 {}
fragment = ui.templates.CodetemplatesGeneratorFragment2 {}
fragment = ui.compare.CompareFragment2 {}
fragment = idea.parser.antlr.XtextAntlrIDEAGeneratorFragment {}
fragment = ui.projectWizard.TemplateProjectWizardFragment {}
fragment = ui.fileWizard.TemplateFileWizardFragment {}
}
language = XtextGeneratorLanguage {
referencedResource = "platform:/resource/de.bmw.rhmi/src/main/java/de/bmw/rhmi/App.xtext"
name = "de.bmw.rhmi.Hmi"
fileExtensions = "hmi"
referencedResource = "platform:/resource/org.eclipse.xtext.xbase/model/Xbase.genmodel"
fragment = grammarAccess.GrammarAccessFragment2 {}
fragment = ecore.EMFGeneratorFragment2 {}
fragment = serializer.SerializerFragment2 {}
fragment = resourceFactory.ResourceFactoryFragment2 {}
fragment = parser.antlr.XtextAntlrGeneratorFragment2 {}
fragment = validation.ValidatorFragment2 {}
fragment = scoping.ImportNamespacesScopingFragment2 {}
fragment = exporting.QualifiedNamesFragment2 {}
fragment = builder.BuilderIntegrationFragment2 {}
fragment = formatting.Formatter2Fragment2 {}
fragment = ui.labeling.LabelProviderFragment2 {}
fragment = ui.outline.QuickOutlineFragment2 {}
fragment = ui.outline.OutlineTreeProviderFragment2 {}
fragment = ui.quickfix.QuickfixProviderFragment2 {}
fragment = ui.contentAssist.ContentAssistFragment2 {}
fragment = junit.JUnitFragment {}
fragment = ui.refactoring.RefactorElementNameFragment2 {}
fragment = ui.templates.CodetemplatesGeneratorFragment2 {}
fragment = ui.compare.CompareFragment2 {}
fragment = idea.parser.antlr.XtextAntlrIDEAGeneratorFragment {}
fragment = ui.projectWizard.TemplateProjectWizardFragment {}
fragment = ui.fileWizard.TemplateFileWizardFragment {}
}
}
}
Why is this happening?
My Idea was to increase the timeout variable for the generator, but I am not sure if that has to do with it or how to do it.
