MethodCallExpr inside lambda in assignment expression cannot be resolved

This case is not currently covered. Thank you for reporting this bug.

[YXL-123]

OK, thank you for your reply.

This is not trivial, because to resolve the println(..) method Javaparser has to resolve the type of the parameter, which is undefined at this stage. I don't see any precision on this point in the JLS. If you can clarify what needs to be done, I can try to resolve this bug quickly.

            public class Lambda {
                interface MyInterface {
                    void doSomething(int a);
                }

                void test(){
                    MyInterface myInterface;
                    myInterface = arg -> System.out.println(arg);
                }
            }

Decompiling the class doesn't provide any information either.

Compiled from "Lambda.java"
public class Lambda {
  public Lambda();
    Code:
       0: aload_0
       1: invokespecial #1                  // Method java/lang/Object."<init>":()V
       4: return

  void test();
    Code:
       0: invokedynamic #2,  0              // InvokeDynamic #0:doSomething:()LLambda$MyInterface;
       5: astore_1
       6: return
}

Thanks, we try to distinguish function overloading by getting the QualifiedSignature of MethodCallExpr and get its method descriptor.

Please don't mix issues.

[YXL-123]

Sorry, I'll create a new issue.
