Is it possible to validate imports like

import xava.util.*

I want to highlight error message that there is no such package 'xava.util'

I know that I can validate member import rule like

Import:
'import' name=[type::JvmType|QualifiedName] wildcard?='.*'?

In that case, if someone input wrong type scope returns null and validator highlight error.

But in the case of package wild card import name can be any string.

Btw xtend just shows warning message that wild card import are deprecated

The common types EPackage doesn't 'model' any Java packages, so you can not have cross references to them.
But if you have a source to tell you whether such a package exists (e.g. JDT), you can write a validation rule and check it.
