Hi,
I am using latest Unity Firebase SDK which has "play-services-resolver_v1.2.102.0" bundled with itself. After resolving dependencies, it logs out this error:

Error archiving ...\com.google.firebase.firebase-core-11.0.4\libs\classes.jar
Exit code: 1
added manifest

...\Temp\zlsack6d.0oc\empty_classes_jar\. : no such file or directory

and then it is finished with "Resolution Succeeded". According to source, I can't find creating empty_classes_jar directory anywhere in your code, therefore, I think there is no such directory at that time.

I also should mention that after the resolution process is completed, the build process fails with error like what is shown in #19 . I think the build error is the result of failure in building "classes.jar" in the first part.

Thanks
