I'm having a service and a receiver described in AndroidManifest.xml, and a couple of js files extending the classes (all taken from nativescript background services example working w/ android's alarmManager). everything seems to be fine when using no webpack or just plain webpack, but goes out of control w/ snapshot generation:

I'm having the same issue. Have any of you found a solution?

rosen-vladimirov commented 4 years ago

Hey guys, Can you please send a package.json and ideally a sample application reproducing the issue. It seems some of the plugins or your local code conflicts with extending the same class multiple times which leads to the error. We cannot determine the cause without more information on this case as the problem seems related to the application itself or the usage of specific plugins.
