Dagger 2 unchecked warnings

Question

In a project where I'm currently working on I've experienced some unchecked warnings related to Dagger 2.

To exclude project related factors I've tried compiling the Dagger 2 examples provided on GitHub and they are also causing these unchecked warnings. See below.

/MY_DIRECTORY/../DaggerApplicationComponent.java:28: warning: [unchecked] unchecked conversion

this.demoApplicationMembersInjector = DemoApplication_MembersInjector.create((MembersInjector) MembersInjectors.noOp(), provideLocationManagerProvider);

required: MembersInjector<Application>

found: MembersInjector

Apparently the create method requires an MembersInjector<Application> but Dagger 2 casts the passed object to an MembersInjector by default.

I would like fix these issues so that the logs remain clean and the buildserver compiles the project again.

Some settings I'm using:

Compile against Android version 23
Dagger version 2.0.1
Dagger compiler version 2.0.1
Javax Annotation jsr250-api version 1.0

What's the solution actually... is it getting the latest dagger2 or suppress the warning ourselves? (if suppress the warning ourselves, how could we do it?) Thanks. — Elye, Apr 26 '16 at 12:11
Would be nice to post your solution here instead of a "thanks! that fixed it!" — Paul Spiesberger, Jul 10 '18 at 11:34

I tried to upgrade Dagger to latest version 2.19, and the issue has gone.
