I know this problem appeared recently on stackoverflow, but I still haven't solved my problem after reading and implementing changes sugested in those questions: 1. Unable to Merge Dex - Android Studio 3.0 2. Android Studio 3.0 Execution failed for task: unable to merge dex 3. Android Studio 3.0 Unable to merge dex 4. Unable to merge dex

Getting to the point: Yesterday (2-11-2017) everything worked perfectly fine, but today I got this error:Error:java.lang.RuntimeException: java.lang.RuntimeException: java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

• I deleted my build forder, rebuilt it etc. etc.
• I updated Android Studio
• I invalidated cashes / restarted Android Studio.

Below I put both build.gradle files and full error message. Hope someone can help me solve this problem.
