Required namespace never defined with goog.requireType

[schmidtk]

Files that are only referenced by goog.requireType are included in the depswriter.py output, but not included in the build because they are not an explicit dependency.

This can be reproduced with the mixed-modules demo by making the following changes:

goog-requiretype.js:

goog.provide('app.googRequireType');

/**
 * @typedef {string}
 */
app.googRequireType;

goog-require.js:

goog.provide('app.googRequire');
goog.requireType('app.googRequireType');

/**
 * @return {app.googRequireType}
 */
app.googRequire = function() {
  return 'from goog.require';
};

Current workaround is to goog.require the file somewhere, but it would be helpful if these could be automatically included in the build by some means.

I get the same error message in my project but I do not know if the cause is the same.
I transpiled my TS project using tsickle and this is the entry file I give to webpack:

goog.module('webmodule.AsklibWebModule');
var module = module || { id: 'webmodule/AsklibWebModule.ts' };
exports.ColorFactory = exports.TYPE_KINDS = exports.NODE_KINDS = exports.avisitor = exports.visitor = exports.logger = exports.factory = void 0;
const tsickle_AsklibEngineFactory_1 = goog.requireType("asklib.AsklibEngineFactory");
const tsickle_Asklog_2 = goog.requireType("asklib.commons.Asklog");
const tsickle_ColorFactory_3 = goog.requireType("asklib.commons.ColorFactory");
const tsickle_AbstractRequestVisitor_4 = goog.requireType("asklib.tree.AbstractRequestVisitor");
const tsickle_RequestNodeKind_5 = goog.requireType("asklib.tree.nodes.RequestNodeKind");
const tsickle_DefaultRequestVisitor_6 = goog.requireType("asklib.tree.visitors.DefaultRequestVisitor");
const tsickle_SimpleType_7 = goog.requireType("asklib.types.SimpleType");
var AsklibEngineFactory_1 = goog.require('asklib.AsklibEngineFactory');
Object.defineProperty(exports, "factory", { enumerable: true, get: function () { return AsklibEngineFactory_1.AsklibEngineFactory; } });
var Asklog_1 = goog.require('asklib.commons.Asklog');
Object.defineProperty(exports, "logger", { enumerable: true, get: function () { return Asklog_1.Asklog; } });
var ColorFactory_1 = goog.require('asklib.commons.ColorFactory');
Object.defineProperty(exports, "ColorFactory", { enumerable: true, get: function () { return ColorFactory_1.ColorFactory; } });
var AbstractRequestVisitor_1 = goog.require('asklib.tree.AbstractRequestVisitor');
Object.defineProperty(exports, "avisitor", { enumerable: true, get: function () { return AbstractRequestVisitor_1.AbstractRequestVisitor; } });
var RequestNodeKind_1 = goog.require('asklib.tree.nodes.RequestNodeKind');
Object.defineProperty(exports, "NODE_KINDS", { enumerable: true, get: function () { return RequestNodeKind_1.RequestNodeKind; } });
var DefaultRequestVisitor_1 = goog.require('asklib.tree.visitors.DefaultRequestVisitor');
Object.defineProperty(exports, "visitor", { enumerable: true, get: function () { return DefaultRequestVisitor_1.DefaultRequestVisitor; } });
var SimpleType_1 = goog.require('asklib.types.SimpleType');
Object.defineProperty(exports, "TYPE_KINDS", { enumerable: true, get: function () { return SimpleType_1.SimpleType; } });

I get a Required namespace "XXX" never definedwith both the goog.require and goog.requireType declarations.
