Custom plugin undefined, other plugins work

Ionic Framework ionic-v3
1

I built a simple cordova plugin just to see it work before I start trying to fill out the native code, and I can’t seem to get a handle on it in the ionic app. My ionic is 2.0.0, my cordova is 6.3.0. Here’s all the source for the plugin:

myplugin
  - src
    - android
        myplugin.java
    - ios
        myplugin.h
    - windows
        myplugin.js
  - www
      myplugin.js
  plugin.xml

There is nothing complex in any of the native files, this is the java file:

public class TravelerSecureServices extends CordovaPlugin {
    @Override
    public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException {
        if (action.equals("coolMethod")) {
            String message = args.getString(0);
            this.coolMethod(message, callbackContext);
            return true;
        }
        return false;
    }
    private void coolMethod(String message, CallbackContext callbackContext) {
        if (message != null && message.length() > 0) {
            callbackContext.success("Successfully Called");
        } else {
            callbackContext.error("Expected one non-empty string argument.");
        }
    }
}

Simple, just returning a string. The plugin js file looks like this:

var exec = require('cordova/exec');

var myplugin = {
	coolMethod: function(){
 	   exec(success, error, "myplugin", "coolMethod", [arg0]);
	}
};

module.exports = myplugin;

The plugin.xml looks like this:

<?xml version='1.0' encoding='utf-8'?>
<plugin id="cordova-plugin-myplugin" 
	version="0.0.1" 
	xmlns="http://apache.org/cordova/ns/plugins/1.0" 
	xmlns:android="http://schemas.android.com/apk/res/android">
	<name>my plugin</name>
	<js-module name="myplugin" src="www/myplugin.js">
		<clobbers target="myplugin" />
	</js-module>
	<platform name="android">
		<config-file parent="/*" target="res/xml/config.xml">
			<feature name="myplugin">
				<param name="android-package" value="myplugin" />
			</feature>
		</config-file>
		<config-file parent="/*" target="AndroidManifest.xml" />
		<source-file src="src/android/myplugin.java" target-dir="src/cordova-plugin-myplugin" />
	</platform>
	<platform name="ios">
		<config-file parent="/*" target="config.xml">
			<feature name="myplugin">
				<param name="ios-package" value="myplugin" />
			</feature>
		</config-file>
		<source-file src="src/ios/myplugin.m" />
	</platform>
	<platform name="windows">
		<js-module src="src/windows/myplugin.js" name="myplugin">
			<runs target="" />
		</js-module>
	</platform>
</plugin>

Note that I have a clobber set. I’ve imported the plugin into my ionic app using ionic plugin add /path/to/myplugin, and the code all shows up in the plugins directory. Everything looks good. When I build and run the app on an android device, I get undefined for all of the following:

myplugin
window.myplugin
window.myplugin.coolMethod()
window.cordova.plugins.myplugin

I’ve tried every place I could think of or find an example of online, and the plugin isn’t there. I’ve tried it with and without <script src="myplugin.js"></script> in the index.html file. I’ve removed and re-added the plugin, removed and re-added the platform, I’ve used ionic build, I’ve used ionic run, and every possible combination of CLI commands and configurations I can think of. What am I missing? I can add more details if needed, and I’ll try any suggestions.

I’m certain it’s something stupid and simple, but so far I haven’t been able to find a complete tutorial or example that actually covers all of this, so I’m sure there’s a step in there that I’m missing. I’ve beat my head on this until I’m out of ideas.

Same Problem here, did you find a solution?
