Error on this fetchAllContacts().stream().forEach(System.out::println); 

Error:(33, 57) java: method references are not supported in -source 1.5
  (use -source 8 or higher to enable method references)

I get this error in Intelij I downloaded the library from GitHub

I understand it is because of the error of java version as the stream().forEach(....

Your java version must be 1.8. If you are using gradle for this project open the build.gradle file and check sourceCompatibility it must be 1.8. I assume that you have the latest java update.

Oki I refreshed the dependencies by changing in sourceCompatibility = 1.8 and now its working. Thanks for the hint
