Hi,I am facing issue after creating FinderImpl in servicebuilder project All method written in LocalserviceImpl throwing null pointer exception. I am using Liferay 7.2 with Fix pack 4.
Step that I have followed.1. Create service builder project and create an entity in service.xml.2. run Build service and did gradle referesh.3. write a method in Entity  Local service Impl  and build service again and deploy.4. When I call method created above in any module it work fine. 5. Now add FinderIml  Class in persistance.impl package  i.e FooFinderImpl  and build service .6. I followed the steps creating FinderImpl provided by Liferay and I have already written FinderImpl in many other Liferay projects in 7.0 and 6.2.
7. After deploying service builder again method we were calling earlier is throwing null pointer exception. 
Thanks
