Bug Report

Problem

Plugins are not restored from package.json. They are only restored if listed in config.xml but since Cordova 9 plugins are to be managed with package.json. Steps to recreate:

1. Create new app: cordova create testPluginRestore com.example.testpluginrestore TestPluginRestore
2. Add platform: cordova platform add android
3. Add plugin: cordova plugin add cordova-plugin-geolocation
4. Check plugin added ok? cordova plugin ls Lists plugin OK. Also entry in package.json is present.
5. Clean plugins and pltfroms rm -rf platforms/ plugins/ node_modules/
6. Prepare android cordova prepare android
7. Check plugins restored cordova plugin ls

What is expected to happen?

• cordova-plugin-geolocation plugin to be restored and listed in the list

What does actually happen?

• cordova-plugin-geolocation is not restored.

@aidanas Can you please test with cordova@nightly and confirm if this is still an issue?

When I tested with nightly and it appears that plugins are being restored correctly.

rm -rf package-lock.json node_modules platforms plugins

The issue you are reporting might exist in 9.x but not in the upcoming 10.x release which is being prepared.

You can test with nightly by updating your global install:

npm uninstall -g cordova
npm install -g cordova@nightly

You might also be able to use npx command instead of upgrading your global install of Cordova.

In your Cordova project directory, you could try this:

rm -rf package-lock.json node_modules platforms plugins
npx cordova@nightly prepare

Please remember that nightly is not production ready as it has not been voted on for release.

@erisu, thanks for the heads up! I can confirm that using Cordova 10 nightly build (10.0.0-nightly.2020.6.29.7b8e8678) it seems to restore plugins OK.

I get however Cannot find module 'properties-parser' error but that could be just broken nightly build or some other, potentially unrelated, issue on my end.

Any ETA on Cordova 10 release dates?

I have a lot of these issues also. Remove the platform Android before your step 5 where you remove those 3 directories, and then add platform again. Cordova prepare doesn't fetch npm modules and plugins, just cordova platform add.

In short, try this sequence

cordova platform rm android
rm -rf platforms/ plugins/ node_modules/
cordova platform add android

It should work on the latest version of cordova cli
