Are you on Windows? This sounds like the same problem as https://github.com/apache/cordova-common/issues/64

Hello all !

I may add that I am encountering this issue too. For me the only workaround was to run the following commands once or twice…

cordova platform rm android
cordova platform add android@8.0.0

When, with the same project, I was on cordova-android@7.1.1, I never encountered this problem. But I decided to upgrade a few days ago and this bug arise.

Regarding the environment, I am on windows 10. Here is the complete environment info:

Cordova:
cordova (cli):      8.1.2 (cordova-lib@8.1.1)
platforms:          "cordova-android": "8.0.0"
fs-extra:           3.0.1

System:
Android SDK Tools:  28.0.3
NodeJS:             10.13.0
npm:                6.8.0
OS:                 Windows 10 v1809

For me, the fs-extra defect referred in the apache/cordova-common#64 issue could well be the source of this bug !

I'm going to close this issue in favour of keeping the discussion in one spot at https://github.com/apache/cordova-common/issues/64. Unfortunately, our ability to solve this problem is largely limited by NodeJS and fs-extra.

@apiaget Your "workaround" to reinstall the android platform is for sure a random and temporary behavior and not a solution. Because this error does not always occur. In my case I always build from a blank (git tracked file only) state. Without node_modules and no platforms folder. A hard-clean. In my case the build fails in most of tries. I don't even know the core of this problem. I hope for a upcoming solution and fast workaround. Currently I can't build the app.

@dpogue This seems to be happen since Cordova-Android 8.0.0. What changed in relation to fs-extra? Maybe Cordova-Android should use older - working - version? In fact, the build nearly always fails. It's a very critical bug. ... What do you think about it? I have not quite understood the problem yet. I'm looking for a workaround. Until jprichardson/node-fs-extra#657 / jprichardson/node-fs-extra#626 is / are fixed.
I just wondering: I this a Cordova-Android 8.0.0 only issue? If yes, what changed? What could be fixed / workaround?

What changed in relation to fs-extra?

As part of the major version bump to several underlying libraries (cordova-common, cordova-lib, cordova-fetch, etc.) we migrated a bunch of code from shelljs to use fs-extra instead. This significantly improved the reliability of tests and resolved several weird bugs that people had been seeing for years. Unfortunately, this issue didn't show up in any of our test suites (which we do run on Windows).

So it's not a change at the cordova-android level, it's in the cordova-common library which is used by all the platforms and the Cordova tooling.

This issue appears to only affect people using Windows, which is probably why it's only getting reported on the Android repo and not iOS.

Thanks.
Just a conclusion of the current situation:
If I understand it correctly. There is a number / bigint issue. Maybe the state.ino (inode) of fs want returns a greater number as the safe integer of JavaScript (53bit). But NodeJS also supports bigint in latest version (10.x) and would probably fix the problem.
Weird that this is only in Windows. Maybe the other OS (linux, darwin) does not have such big numbers for the inode. Idk.

In fact, with this problem I can't build my app. It's a K.O.
Workarounds:
a) Revert to Cordova-Android 7.x.
b) Use another OS (e.g. Linux) to build. No guarantee, but it seems to be a Windows only issue.
c) Fork extra-fs and fix it. (recommended) but I need it now. Long way until merge and discussions. Also new Cordova version.
d) Revert Cordova and replace fs-extra. (It's a solution, nothing else. 😃 )
e) Any idea to keep Cordova-Android 8.0.0. I could overwrite the compiled JavaScript of fs-extra to remove the ino-validation. Quick and dirty. Or work with my own fork.

Yes.

Should be fixed in v8.0.1
