IntelliJ creates import statements which fail on runtime after (ts) transpile

When coding with IntelliJ which is fully typescript capable, when coding a line like this:

let message:GmailMessage = getCurrentMessage(event);

IntelliJ generates an import statement like this:

import GmailMessage = GoogleAppsScript.Gmail.GmailMessage;

This import statement becomes after transpiling and pushing:

var GmailMessage = GoogleAppsScript.Gmail.GmailMessage;

But this statement fails during script runtime. Problem is, without the import, I don’t have any autocomplete in my IDE and of course the IDE flags the source as invalid.

How to handle that situation? I simply can’t remove those lines manually in the Online Editor every time I have pushed. That would be a nightmare 😃

Expected Behavior

No runtime error.

Actual Behavior

ReferenceError: “GoogleAppsScript” is not defined. [line: 9, function: , file: src/GetContextualAddOn]

Steps to Reproduce the Problem

1. use IDEA to code typed source code against Gmail AppsScript API
2. push the results

Specifications

• latest IntelliJ IDEA on Mac
• Version (clasp -v): clasp 1.5.0
• OS (Mac/Linux/Windows): Mac

Can you try installing the latest version of clasp 1.5.1, and see if the IntelliJ setup works?

I will experiment with a solution that comments out the import line when pushing.

// import GmailMessage = GoogleAppsScript.Gmail.GmailMessage;
var greeter = function (person) {
    return "Hello, " + person + "!";
};
function testGreeter(event) {
  let message:GmailMessage = getCurrentMessage(event);
}

I created the 3rd party lib, so I can follow-up there.
