I\'m using Gradle to build a java project. When I run any task (assemble, test). I get randomly an error :
Could not create service of type FileHasher using
This was same problem for me before some days and now only it's your or the user reading this solution.
Uninstall full android studio (means- 'after uninstall from control panel, delete folders of Android Studio,') folders to be deleted:
C:\Program Files -> Android, C:\Users{user folder name} -> .android & .gradle & {other folders related to Android Studio}
Reinstall form it's .exe and make sure your PC in connected with internet and with proper speed.
Download all SDK files as mention in that and keep downloading in Android Studio only. [do not download form other source- otherwise it will show errors, be careful]
Click on new project and select empty project and give the name and click on finish.
you will redirect to another window and than the main thing starts that is installation of GRADLE so for this you should have high connectivity of internet and that it will download automatically and and and now your are ready to go.
