Trying to upgrade past 8.13.17 causes Error while merging dex archives:

[chrisbarry]

Hi,

I'm not sure if this is the right place to ask this, but I am at the end of my teather, so any help would be mightly appricated..

I have an android app, and when I update past 8.13.17 I get:

Error while merging dex archives

Execution failed for task ':app:multiDexListAppName.

A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade
Error while merging dex archives:

I have used:

resolutionStrategy.force 'io.michaelrocks:libphonenumber-android:8.13.18'

If I don't use that, I get:

Conflict(s) found for the following module(s):
- io.michaelrocks:libphonenumber-android between versions 8.13.18 and 8.12.52

(8.12.52 was the last version I was on)

Any ideas how to resolve this or why it breaks past that version number. The app is quite old but still, it seems odd and is not an easy error message to debug?

Any help supremely appricated...
