Exception in thread “main” java.lang.NoClassDefFoundError: junit/textui/ResultPrinter

Question

I\'m trying to compile my Android project in Android Studio 0.3.0. Today I get the following error:

Exception in thread \"main\" java.lang.NoClassDefFoundErr         


        

Answer 1

Usually this problem is caused because of wrong test type: Junit instead of Android Test

Answer 2

Force the project to "sync" via menu: Tools > Android > Sync Project with Gradle Files or force the project to "sync" by making a fake change in build.gradle file (add a space and then delete it and then click "sync now").
