Runner

Runner executes action trees and discovered factories.

Create a runner

var runner = Runner.defaultRunner();

var custom = Runner.builder()
        .configuration(configuration)
        .listener(listener)
        .build();

Builders are reusable; calling build() produces a new runner from the builder's current configuration.

Run methods

• run(Action) returns Result.
• run(Selector) returns Optional<Result>.
• runAndReturnExitCode(Action) and runAndReturnExitCode(Selector) return 0 or 1.
• runAndExit(...) terminates the JVM with the derived code.
• run() discovers factories from the classpath and returns an exit code.

Runner.main(String[]) calls Runner.builder().build().run() and exits with the returned code.
