1. A concise explanation of the problem you're experiencing.
Advice on how to re-create a local version of the cesium.js file after making minor edits to one of the modules (layerimagefeatureinfo.js).
3. Context. Why do you need to do this? We might know a better way to accomplish
your goal.
I am using the excellent tutorial https://cesium.com/blog/2016/05/18/an-introduction-to-cesium-android-apps-with-cordova/ as a base for creating a basic android app.
Following the tutorial, I copied directory Cesium from the build subdirectory (downloaded from cesium.org) into www/ directory. That all worked fine. But I have had to make minor changes to layerimagefeatureinfo.js so I need to re-create the Cesium directory so that my changes are included in cesium.js.
This is probably a straighforward thing to do but as a beginner I am not sure what to do next!
4. The Cesium version you're using, your operating system and browser.
Cesium 1.42, Windows 10, Firefox and Chrome.
