Copies 2 features from different Pekko repos that are useful to share around our other Pekko repos.

• PekkoDependency has code to get latest release and snapshot versions for core Pekko jars
• Mima builds on sbt-mima-plugin and provides support for looking up exclude files in mima-filters directories.
  • see https://github.com/apache/incubator-pekko/blob/main/CONTRIBUTING.md#binary-compatibility

v0.3.0 and above also contains an autoplugin that enables Scala compile inlining (Scala 2 only). This behaviour cannot be enabled on any Pekko 1.0.x module.

The default is:

ThisBuild / pekkoInlineEnabled := true

On 1.0.x branches and on main branch if we haven't forked a 1.0.x branch yet, we must set:

ThisBuild / pekkoInlineEnabled := false

When running local builds you can use sbt -Dpekko.no.inline to avoid the inlining. It is very expensive to inline (uses a lot more CPU and memory when it is enabled).

This is usable as is in v0.2.x but in v0.3.0 and above, you need to add a file to your project dir like PekkoCoreDependency.scala

• defaults to 1.0.0 because we want to maintain compatibility with all Pekko 1 releases
• -Dpekko.build.pekko.version=latest-release will find latest release regardless of version number (December 2023 - this evals to 1.0.2)
• -Dpekko.build.pekko.version=main will find latest snapshot for main branch (December 2023 - this evals to 1.1.0-M0+...-SNAPSHOT)
• -Dpekko.build.pekko.version=1.0.x will find latest snapshot for 1.0.x branch
