Hello,

currently I have a problem with my Xtext project. I use a genmodel created by myself from several ecore models. When I build my workspace the operation:

"Updating resource description for xhtml.ecore" takes forever. I cannot cancel it. I need to kill eclipse.

The problem lies in the xhtml.ecore file created by emf. It has ~12.000 lines.

I think the problem lies in the class

I found bugs that had similar problems Bug Eclipse 372527, code google com/p/protobuf-dt/issues/detail?id=206

I work with:
Eclipse SDK

Version: 4.2.0
Build id: I20120608-1400

Xtext SDK 2.3.0.v201206120633


I will attach the project. I hope you can help me.

Thanks in advance.

Svenja

Hi,

guess this is the http://www.w3.org/1999/xhtml/datatypes/ http://www.w3.org/1999/xhtml etc problem.
w3 doesnt like java programs polling their dtd and makes this very very slow.

Hi Christian,

this looks like this issue here:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=385718

A possible solution would be to ensure that the plugin registry contains
entries for those URIs, e.g. by registering a generated EPackage or
something.

Regards,
Sebastian

Hi,

I changed my settings to only use generatedEPackages:

	bean = StandaloneSetup { 
		
		scanClassPath = true
		platformUri = "${runtimeProject}/.."// The following two lines can be removed, if Xbase is not used.
		registerGenModelFile = "platform:/resource/com.yakindu.requirements.req/model/reqif10.genmodel"
		registerGeneratedEPackage= "datatypes.DatatypesPackage"
		registerGeneratedEPackage= "xhtml.XhtmlPackage"
		registerGeneratedEPackage="reqif10.Reqif10Package"
	}


But then I get the following Exception

Hi Svenja,

the EPackages are probably too large to create static initializers. EMF
generated dedicated ecore files in these cases that will be loaded at
runtime. Those seem to be missing in your projects.

Sebastian

I deleted the xhtml.ecore because it caused the above mentioned problems.

Hi, now it works. I enlarged the eclipse memory, cleaned the whole workspace.

Thanks for your suggestions.
