Cordova CLI build failed

[ruudruud]

While building an iOS cordova application with Cordova CLI the build crashes with MMedia. All other ad network plugins work perfectly (Flurry, InMobi, etc.).

Commands used:

cordova plugin add com.google.cordova.admob-mmedia
cordova build ios

Error:

Are you using Xcode 5 or 6? If using xcode 5, upgrade to 6 first.

Thank you for your quick reply. I am using Xcode version 6.2 (6C131e), this version was released 3 days ago.

I tried building and it did fail.

After some study, I think it's because the mmedia mediation adapter is not compatible with new admob sdk 7.0. You will find in the change log of admob sdk 7.0 release notes here:
https://developers.google.com/mobile-ads-sdk/rel-notes#ios
As mentioned:
"Replaced GADAdMobExtras and DFPExtras with a single GADExtras class"

The mmedia adapter was build in Jun 2014, so it's outdated. Will contact millennial media to update the adapter, but they are quite slow to response.

Ugh, that's bad news. That is a big issue. Hopefully they will update the adapter soon.

Thanks for finding this issue so fast, and keep me posted please.

This also appears to be relevant. https://groups.google.com/forum/#!topic/google-admob-ads-sdk/FH9y3S58JRk

It looks like the adapter has been updated, just not the plugin.
