Firebase Java Admin SDK graalvm minimal configuration

How to make firebase-admin to work with GraalVM native-image?

You need to add the following to your project:

• src/main/resources/META-INF/native-image/firebase-admin/firebase-admin/resource-config.json (required by most SDK clients)

{
  "resources" : {
    "includes" : [
      {
        "pattern" : "admin_sdk.properties"
      }
    ]
  }
}

• src/main/resources/META-INF/native-image/firebase-admin/firebase-admin/reflect-config.json (contains minimal example to make FCM push message sending work, add classes you need in your project)
