GitHub Issue: Duplicate GUID errors due to unnecessary directory

[ryohorie]

When importing the com.google.ads.mobile.mediation.line package into Unity, a large number of GUID conflict warnings are output, such as:

It seems that the following directory is mistakenly included in the package and is causing the conflict:

It contains a duplicate copy of the mediation line plugin, which Unity tries to import along with the top-level files, leading to GUID duplication errors.

Please consider removing the following directory from the repository:

/Line/packages/com.google.ads.mobile.mediation.line

Environment

Unity version: (e.g., 2022.3.x)

Google Mobile Ads Unity Plugin version: v10.0.0 (but also affects older versions)

Platform: iOS and Android

Let me know if you’d like help testing a fixed version.
Thanks for your work on these mediation adapters!
