Description

When building Hyperloop for Android, sometimes one of the following errors is thrown:

[INFO]  Starting Hyperloop assembly
[INFO]  [Hyperloop] Using system metabase cache file at /var/folders/tt/7hv0vw1d4nx64kbpcdd4dsn00000gn/T/hyperloop_android-23_metabase.4b1ef509144aeedbb0887170e4fa336933582ed3.json.gz
[INFO]  Skipping Hyperloop compile, no usage found ...
[INFO]  Finished Hyperloop assembly
[ERROR] read ECONNRESET

or (twice now)


[INFO]  Starting Hyperloop assembly

Cannot read property 'shift' of undefined
2017-03-28T08:40:02.078Z | ERROR  | Cannot read property 'shift' of undefined

This happens randomly and can be resolved by doing a clean build. Even when not changing anything Hyperloop-related, this happens from time to time. *EDIT*: Additional logs (only occurred once in trace-mode):

So I don't actually use wrench in hyperloop JS code itself, so I think this is actually coming through from the node-appc dependency (as you can see in the file paths above). It's possible that [~hansknoechel]'s PR for node-appc here would fix it? https://github.com/appcelerator/node-appc/pull/122

This was caused by running multiple .aar transforms in parallel. During the transform we copy the assets directory which caused unexpected behavior when multiple I/O operations happened on the same destination folder.

I tested with this environment: Node Version: 6.10.3 NPM Version: 3.10.10 Mac OS: 10.12.4 Appc CLI: 6.2.2 Appc CLI NPM: 4.2.9 Titanium SDK version: 6.1.1.v20170621181735 Appcelerator Studio, build: 4.9.0.201705302345 Xcode 8.3.2 Hyperloop version 2.1.2 Beta 3 I was able to reproduce the bug using Hyperloop version 2.1.1 and 5 aar files in the project: [INFO] Starting Hyperloop assembly 2017-06-23T00:00:12.998Z | ERROR | An uncaught exception was thrown! Cannot read property 'shift' of undefined 2017-06-23T00:00:12.999Z | ERROR | Cannot read property 'shift' of undefined I then switched to Hyperloop 2.1.2 Beta 3, and built the same app in succession 10 times, and the error did not occur.
