Hi all,
I am exporting my xtext project to the command-line/standalone mode. This is achieved without a problem
but now I need to modify it in order to accept multiple files (in order to resolve cross-references
between files). To do this, I have implemented a version of the suggestion in
http://www.eclipse.org/forums/index.php/m/761659/?srch=standalone+multiple+files#msg_761659
in which the model of the secondary files are added for the Resource of the main file.
ResourceSet set = resourceSetProvider.get();
Resource compositeResource = set.getResource(URI.createURI(mainfilename),true);
for (String otherfilename : getOtherSourceFiles()) {
Resource modelFromFile = set.getResource(URI.createURI(otherfilename ), true);
compositeResource.getContents().addAll(modelFromFile.getContents());
}
List<Issue> list = validator.validate(compositeResource, CheckMode.ALL, CancelIndicator.NullImpl);
The problem is, although the validation works, I cannot get ride of this exception:
0 ERROR LazyLinkingResource - resolution of uriFragment 'xtextLink_::0.0.0.1.0::0::/3' failed.

Hi,
why do you do the compositeResource.getContents().addAll(modelFromFile.getContents()); at all?
"the model" is the set off all resources aka resourceset.
if you add all required resources to the resourceset you wont get errors like that.
you may call compositeResource.getContents().addAll(modelFromFile.getContents());
to resolve all lazy cross refs after you added all resources to the resourceset
