Crosswalk版本低于2.0.0的离子生成错误-“ XWalkWebViewEngine不是抽象的，并且不会覆盖抽象方法”

Question

Have come back to an Ionic project after a year to update a couple of things but now the project won't build.

The issue looks to be Crosswalk when updating to the latest version it builds fine but the device I am building for specific uses Android 4 which is only supported by cross walk 1.6.0 - 1.8.0.

The error shown on the output is:

..platforms/android/src/org/crosswalk/engine/XWalkWebViewEngine.java:55:
error: XWalkWebViewEngine is not abstract and does not override abstract method
evaluateJavascript(String,ValueCallback<String>) in CordovaWebViewEngine public
class XWalkWebViewEngine implements CordovaWebViewEngine {

I have been searching the for a while and nothing had worked. Removing all plugins and platforms and reinstalling in various orders, updating Android SDK etc.

I am on a new machine so not sure if it's linked the NPM version or Cordova version. For info: npm is 4.3.0 and Cordova is 6.5.0
