Source code

We use Git as source control management.

The blessed OptaPlanner repositories, summarized below, are hosted on GitHub.


The source code for OptaPlanner itself, examples and documentation.

  1. Get the source code locally with Git:

     $ git clone

    If you don’t have a GitHub account or your local Git installation isn’t configured with it, use this command instead, to avoid an authentication issue:

     $ git clone optaplanner
  2. Build it with Maven:

     $ cd optaplanner
     $ mvn clean install -DskipTests

    The first time, Maven might take a lot time, because it needs to download jars.

  3. Run the examples:

     $ cd optaplanner-examples
     $ mvn exec:java
  4. Edit the sources in your favorite IDE (such as IntelliJ IDEA, Eclipse or NetBeans).

  5. Optional: Use a Java profiler (such as JProfiler or VisualVM).

  6. Optional: Write some documentation in AsciiDoc.
