Can you please try to build a sample project that comes with solar2d for example in Sample Code folder > Physics > HelloPhysics project.
Looking into the exception I can understand that licensing-google could not be found. Have you included in your build settings file according to https://docs.coronalabs.com/api/library/licensing/index.html
I found a similar issue about licensing-google issue due to old project migrating to new one as there has been some structural changes. Corona-3552 (Project Templates - App) Android build Error - Missing licensing-google.jar. Try building an empty project and see whether it builds or not
