Bug Report

Problem

Running cordova prepare errors with returns "Source and destination must not be the same"

I also get the error when running cordorva build android and cordova platform add android

What is expected to happen?

cordova prepare completes successfully

What does actually happen?

any cordova android command fails with the error message

Information

I did find this closed bug: #693 and tried the suggestions, but that didn't fix my issue.

Here is the output from cordova prepare --verbose
No scripts found for hook "before_prepare".

Deleting and recreating the project, with the same versions of Cordova, platforms and plugins is able to build successfully now.

Source and destination must not be the same

This was a bug inside the fs-extra package if I recall correctly. If you had cordova / cordova-android installed before, it was possible it was installed at the time where the bugged version was the latest version.

When recreating/reinstalling the project (presumeably wiping package-lock and node_modules), when reinstalling NPM will fetch the latest patch which contains the fix.

Deleting node_modules & package-lock.json and then running npm install should yield the same results as well.
