AST resolve bindings without dependencies [message #1735078]

Hello,
i want to use JDT to gather some metrics about different projects. The problem is i don't have the dependencies, only the source-code and i can't get the ASTParser to give me all the information that are possible to retrieve.
Example:

package xyz.exemplator.parser.java;

import org.eclipse.jdt.core.dom.AST;
import org.eclipse.jdt.core.dom.ASTParser;

/**
 * @author LeanderK
 * @version 1.0
 */
public class Main {
    public static void main(String[] args) {
        String x = "a";
        ASTParser parser = ASTParser.newParser(AST.JLS8);
        parser.anotherMethod()
    }
}

without the jet dependency i can still gather the information that someone called org.eclipse.jdt.core.dom.ASTParser.newParser() and org.eclipse.jdt.core.dom.ASTParser.anotherMethod(). But when i try to resolve the binding i get RecoveredTypeBinding and getPackage() returns the package of main and not org.eclipse.jdt.core.dom.ASTParser

Without the dependencies you can still parse the sources into an AST, right, but that's all - you're stuck at the syntactic level.
Any semantic analysis starting by resolving type bindings needs the dependencies to be present. I don't see a way around that.
How should JDT guess the type of anotherMethod() if its declaring class cannot be found??
