Akka archetype bat script needs major rework

[jroper]

See

https://github.com/sbt/sbt-native-packager/blob/0b3516496467f316660bcedf4463c5308fb83af4/src/main/resources/com/typesafe/sbt/packager/archetypes/akka-bat-template

• JAVA_OPTS is hard coded, with no possibility to override it with custom memory or JVM arguments.
• The main bat script contains a lot of very useful functionality, such as logic for locating the right Java version, logic for configuring using environment variables, etc, which is missing from this template.

The bash script suffers from similar problems, but at least it doesn't hard code JAVA_OPTS with no possibility to override.

Could we customize the existing bash/bat scripts in a way suitable for Akka kernel apps? So we only have to maintain one start script. WDYT?

[jroper]

I think that would be a great way to do it.

We (Akka Team) would like to remove the AkkaAppPackaging and instead document a migration path to JavaServerAppPackaging in the Akka documentation. Something like akka/akka#17065.

Next step would be to document a clean usage of JavaServerAppPackaging and an ordinary main class for packaging and running an Akka application. Nothing special as far as I can see.

WDYT about removing AkkaAppPackaging?

There's no flexible code as no code

So I'm all about removing if we have to maintain less bash/scala/sbt code without losing any functionality.

We deprecated AkkaPackaging and will remove it.

@muuki88, could you remind relevant discussion? I recently tried to find it and failed..

[patriknw]

Thanks! We have updated the Akka documentation to recommend the JavaServerAppPackaging.

Awesome, thanks @patriknw

@kardapoltsev No, everything came a bit abruptly. However this is the better way to go.
