Android Studio 3.0 Unable to merge dex

Question

Just Updated android studio from 2.3.3 to 3.0 now I am having the error

Error:Execution failed for task \':app:transformDexArchiveWithExternalLibsDexMergerFo         


        

Answer 1

It started happening in my case after adding the following dependency.

implementation 'com.getbase:floatingactionbutton:1.9.0'

I've tried all suggestions published here and in other places, but nothing has worked.

I've tried then a common solution that helped in many other cases and it worked. I've simply used "Sync project with gradle files" from the following menu that can be found in Tools.
