I met the same problems and has solved   Due to my situation  I guess your build gradle file for app project contains snippets below   android               buildTypes           debug               release               dexOptions                 but actually  dexOptions is not a build type  you should move dexOptions section out buildTypes  like this   android               dexOptions                          buildTypes           debug               release                 Hope that can help someone

It seems like it s a bug on Gradle  This solves the problem for me  but it s not a solution  We have to wait for a new version fixing this problems   On build gradle in the project set classpath  com android tools build gradle 2 3 3  instead classpath  com android tools build gradle 3 0 0    On gradle-wrapper properties set https   services gradle org distributions gradle-3 3-all zip instead https   services gradle org distributions gradle-4 1 2-all zip

Make sure you have disabled  Offline work  in Gradle settings  Setting- Build  Execution  Deployment- Build Tools- Gradle    I made this mistake  I followed a guide on speeding up gradle builds and had turned on the Offline work option  If that is enabled  Gradle won t be able to download any new dependencies and hence will result in the  Unable to resolve dependency  error

I know none of the above solutions is gonna work as I have remained stuck into this sort of issue a long time  finally resolved this issue after watching the issue very carefully  which is pointing that      Unable to resolve dependency for   app dexOptions compileClasspath     Could not resolve project   library Name    You need to make a sure and double check if the class is residing there  This one thing will prove much helpful to many I guess because focusing on this point took me much closer to the solution  Now if nothing exists in that folder path you need to get the whole stuff like src folder build folder etc everything  copy that and paste it over there sync rebuild project  if needed try invalidate and restart android studio  Hope so this will get you out of trouble as happend in my case   Thanks

I spent a lot of time on this issue and none of above solutions work for me  The names and number of build types were also exactly equal in both app and library project    The only mistake I was making was - In library project s build gradle  I was using line      apply plugin   com android application    While this line should be -     apply plugin   com android library    After making this change  this error got resolved

This may also happen when you add a reference to the feature module that uses the incorrect plugin type  Simply change com android application to com android feature or com android library  https   i stack imgur com NDjnG png

This thread seems to have wondered a bit  however as relating to the original question   not only do you have to have your buildTypes in both build gradle files  you need to have your productFlavors  if you are using them of course  in both build gradle files as well
