Unify rpm/debian maintainer scripts

Maintainer Scripts

The rpm and debian maintainer scripts have grown over the past years in sbt-native-packager. There settings for rpm scriplets (e.g. rpmPre) with hard to use types (Option[String]) or no helper methods for the debianMaintainerScripts.

With this milestone we introduce a new task-setting:

maintainerScripts: Map[String, Seq[String]]

This will serve as the low level data-structure for all package formats that use maintainer scripts. We have plenty of docs to support you:

• RPM migration
• Debian docs
• Scaladoc for helper methods

To give you a peak what it looked before and after

Before

rpmPostun := rpmPost.value.map { content =>
  s"""|$content
     |echo 'hello, world
     |""".stripMargin
  }.orElse {
   Option("""echo 'hello, world"
   """.stripMargin)
  }

After

import RpmConstants._
maintainerScripts in Rpm := maintainerScriptsAppend((maintainerScripts in Rpm).value)(
   Postun -> "echo 'hello, world'"
)
