--prod builds suddenly failing

Ionic Framework ionic-v3

I suddenly have an issue creating production builds

ionic cordova run android

works fine and generates a debug build on the device.

But all of a sudden if I try

ionic cordova run android --prod

I get this in the console:

[15:36:37]  build prod started ...
[15:36:37]  clean started ...
[15:36:37]  clean finished in 3 ms
[15:36:37]  copy started ...

[15:38:54]  postprocess started ...

I’ve uninstalled Node and re-installed it and uninstalled and re-installed ionic and cordova. But the same thing happens.

Here’s my Ionic Info output

cli packages: (/Users/richardshergold/IonicProjects/myproject/node_modules)

    @ionic/cli-utils  : 1.10.2
    ionic (Ionic CLI) : 3.10.3

global packages:

    Cordova CLI : 7.0.1

local packages:

    @ionic/app-scripts : 2.1.4
    Cordova Platforms  : android 6.2.3
    Ionic Framework    : ionic-angular 3.4.0

System:

    ios-deploy : 1.9.0
    Node       : v7.10.1
    npm        : 4.2.0
    OS         : macOS Sierra
    Xcode      : Xcode 8.3.3 Build version 8E3004b

I chose to install Node 7.10.1 because the first time I tried 6.11.3 and that didn’t solve the problem (can I use the very latest - 8.5?)

Ionic serve works fine. Any ideas?

I don’t see any errors in your console output for the build --prod.

Did you copy and paste everything or does it just stop at postprocess started?

It might be helpful if you add a --verbose flag to the build command to get more details on where it might be hanging up.

Try creating a blank and and see if you can build that.

This turned out to be a problem with the latest App Scripts (2.1.4) which failed to build for Production due to a Source Maps issue (I had generated source maps for Ionic Pro Monitoring earlier in the day). Stepping down to 2.0.1 fixed the issue.

BTW Dan Bucholtz (Ionic) helped me out with this last night so they are aware of the issue and he says it will be fixed in the next release.
