# Apache Pekko (Cluster) Management

This repository contains interfaces to inspect, interact and manage various Parts of Apache Pekko, primarily Pekko Cluster.
Future additions may extend these concepts to other parts of Apache Pekko.

Apache Pekko Management is a fork of [Akka Management](https://github.com/akka/akka-management)

## Documentation

The documentation is available at
[pekko.apache.org](https://pekko.apache.org/docs/pekko-management/current/).

## Building from Source

### Prerequisites
- Make sure you have installed a Java Development Kit (JDK) version 8 or later.
- Make sure you have [sbt](https://www.scala-sbt.org/) installed.
- [Graphviz](https://graphviz.gitlab.io/download/) is needed for the scaladoc generation build task, which is part of the release.

### Running the Build
- Open a command window and change directory to your preferred base directory
- Use git to clone the [repo](https://github.com/apache/incubator-pekko-management) or download a source release from https://pekko.apache.org (and unzip or untar it, as appropriate)
- Change directory to the directory where you installed the source (you should have a file called `build.sbt` in this directory)
- `sbt compile` compiles the main source for project default version of Scala (2.13)
    - `sbt +compile` will compile for all supported versions of Scala
- `sbt test` will compile the code and run the unit tests
- `sbt testQuick` similar to `test` but when repeated in shell mode will only run failing tests
- `sbt package` will build the jars
    - the jars will built into target dirs of the various modules
    - for the the 'discovery-aws-api' module, the jar will be built to `discovery-aws-api/target/scala-2.13/`
- `sbt publishLocal` will push the jars to your local Apache Ivy repository
- `sbt publishM2` will push the jars to your local Apache Maven repository
- `sbt docs/paradox` will build the docs (the ones describing the module features)
    - `sbt docs/paradoxBrowse` does the same but will open the docs in your browser when complete
    - the `index.html` file will appear in `target/paradox/site/main/`
- `sbt unidoc` will build the Javadocs for all the modules and load them to one place (may require Graphviz, see Prerequisites above)
    - the `index.html` file will appear in `target/scala-2.13/unidoc/`
- `sbt sourceDistGenerate` will generate source release to `target/dist/`
- The version number that appears in filenames and docs is derived, by default. The derived version contains the most git commit id or the date/time (if the directory is not under git control).
    - You can set the version number explicitly when running sbt commands
        - eg `sbt "set ThisBuild / version := \"1.0.0\"; sourceDistGenerate"`
    - Or you can add a file called `version.sbt` to the same directory that has the `build.sbt` containing something like
        - `ThisBuild / version := "1.0.0"`
