Source and destination must not be the same.

Bug Report

Problem

Since cordova-android 8.0.0 we have build problems. In most of cases we got the error “An error occurred while running subprocess cordova.” and the last line “Source and destination must not be the same”. Sometimes, the build is ok. - We always check out the git repository of the app. (hard clean)

What is expected to happen?

Build successfully.

What does actually happen?

Build failed.

Information

This error is not 100% reprocable. But about 80%. I just updated Cordova-Android. I expecting the node plugin fa-extra. Maybe Cordova-Android uses this with wrong attributes?

Command or Code

ionic cordova build android --release --prod --generateSourceMap false But also ionic cordova build or cordova build.
