Xtext project JDT Independence - xtext

Question

I created editor with Xtext 2.9.1 and now I want to make it independent of JDT. I followed this guide https://eclipse.org/Xtext/documentation/307_special_languages.html
but it does not seem to work. This is my ErrmsgUiModule.xtend
#FinalFieldsConstructor
class ErrmsgUiModule extends AbstractErrmsgUiModule {
override configure(Binder binder) {
super.configure(binder);
binder.bind(DefaultHighlightingConfiguration).to(ErrMsgHighlightingConfiguration);
binder.bind(DefaultSemanticHighlightingCalculator).to(ErrorSemanticHighlightingCalculator);
}
override bindIResourceForEditorInputFactory() {
return ResourceForIEditorInputFactory
}
override bindIResourceSetProvider() {
return SimpleResourceSetProvider
}
override provideIAllContainersState() {
return Access.getWorkspaceProjectsState()
}
}
I checked every overwritten method with debugger and all 3 methods are called. I did not created my own project wizard so this should be enough.
But still after plugin installating the Java project wizard becomes available...
/Edit:
To provide more information, this is project's mwe2 file
module com.xxx.lang.errmsg.GenerateErrmsg
import org.eclipse.xtext.xtext.generator.*
import org.eclipse.xtext.xtext.generator.model.project.*
import org.eclipse.xtext.ui.generator.*
var rootPath = ".."
Workflow {
component = XtextGenerator {
configuration = {
project = StandardProjectConfig {
baseName = "com.xxx.lang.errmsg"
rootPath = rootPath
runtimeTest = {
enabled = true
}
eclipsePlugin = {
enabled = true
}
eclipsePluginTest = {
enabled = true
}
createEclipseMetaData = true
}
code = {
encoding = "windows-1250"
fileHeader = "/*\n * generated by Xtext \${version}\n */"
}
}
language = StandardLanguage {
name = "com.xxx.lang.errmsg.Errmsg"
fileExtensions = "msg"
fragment = formatting.Formatter2Fragment2 auto-inject {}
serializer = {
generateStub = false
}
validator = {
// composedCheck = "org.eclipse.xtext.validation.NamesAreUniqueValidator"
}
}
}
}
and this is list of Dependencies from plugin.xml for various projects:
project com.xxx.lang.errmsg
org.eclipse.xtext,
org.eclipse.xtext.xbase,
org.eclipse.equinox.common;bundle-version="3.5.0",
org.eclipse.emf.ecore,
org.eclipse.xtext.xbase.lib,
org.antlr.runtime,
org.eclipse.xtext.util,
org.eclipse.xtend.lib,
org.eclipse.emf.common,
org.objectweb.asm;bundle-version="[5.0.1,6.0.0)";resolution:=optional,
org.eclipse.xtext.ui
project com.xxx.lang.errmsg.ui
com.xxx.lang.errmsg,
com.xxx.lang.errmsg.ide,
org.eclipse.xtext.ui,
org.eclipse.xtext.ui.shared,
org.eclipse.xtext.ui.codetemplates.ui,
org.eclipse.ui.editors;bundle-version="3.5.0",
org.eclipse.ui.ide;bundle-version="3.5.0",
org.eclipse.ui,
org.eclipse.compare,
org.eclipse.xtext.builder,
org.eclipse.xtend.lib;resolution:=optional,
org.eclipse.xtext.xbase.lib,
org.eclipse.xtext.xbase.ui
/Edit2: According to this topic https://bugs.eclipse.org/bugs/show_bug.cgi?id=336217, I also tried to disable all org.eclipse.jdt* plugins in run configuration. This is what i get http://pastebin.com/Wi0gzceM

You have to remove the dependencies on org.eclipse.xtext.xbase and org.eclipse.xtext.xbase.ui from your runtime and UI project.
Make sure if you open the Plug-in Dependencies in the Package Explorer that you do not see org.eclipse.jdt.core in the list. If so, there is another plug-in having a (transitive) dependency. Find out which and remove.
