getting the file path and accessing project files [message #1734941]

I am trying to validate the existence of a file in the project:

@Check
def checkConfigFile(ConfigFile configFile) {

val suitePath = configFile.eResource.URI.toPlatformString(true)
val config = Paths.get(suitePath).resolveSibling(configFile.file)
val msg = "File does not exist"
println("checking the path " + config )

if (!config.toFile.exists) {
println("not found " + config)
error(msg, MyDslPackage.Literals.CONFIG_FILE__FILE, "some issue")
}
}

I have seen a similar post http://stackoverflow.com/questions/7242403/a-better-way-to-get-files-within-a-project-using-eclipse-and-xtext

and
http://stackoverflow.com/questions/23630118/xtext-get-the-absolute-path-of-the-generated-files

and
http://stackoverflow.com/questions/22377592/xtext-get-project-root-directory-from-validator

but was not able to figure out how to add org.eclipse.core.resources to plugin.xml
or inject an instance of IFileSystemAccess into the validator.

Is there a detailed documentation showing how to achieve this?
An advice of the best approach is highly appreciated.

Thank you

Is this Code targeting standalone or eclipse.

Using resources plugin works in eclipse only.

You can add org.eclipse.core.resources to the manifest

Christian,
Adding org.eclipse.core.resources as an OSGI import did the trick.
I will need a more generic solution if possible, as I would like to make it available for the interrupter. For now eclipse support is enough to keep me going.
If you have a more generic solution (eclipse and standalone) then please do let me know.

Thank you a lot
