=== Code standards

Your code is automatically formatted according to the Import and Code Style conventions during every Maven build. CI checks enforce those conventions too, so be sure to build your project with maven before creating your PR:

mvn clean install

For information about how to set up code style checks, see https://github.com/kiegroup/optaplanner/blob/main/build/optaplanner-ide-config/ide-configuration.adoc[IDE Setup Instructions].

=== Building your OptaPlanner project

Use one of the following ways to build your OptaPlanner project:

• :rocket: build-fast: mvn clean install -Dquickly skips any checks and code analysis (~1 min)

• :hammer: build-normally: mvn clean install runs tests, checks code style, skips documentation (~17 min)

• :receipt: build-doc: mvn clean install at optaplanner/optaplanner-docs creates asciidoctor documentation target/optaplanner-docs-*/html_single/index.html (~2 min)

• :mechanical_arm: build-all: mvn clean install -Dfull runs all checks + creates documentation and distribution files (~20 min)
