Code generator library for automatic creating picocli base command

Example

Application.java

@BaseCommandConfiguration(
    name = "tool",
    description = "My awesome tool"
)
public class Application {
    public static void main(String[] args) {
        final BaseCommand command = new BaseCommand(); // generated class
        final CommandLine commandLine = new CommandLine(command);
        System.exit(commandLine.execute(args));
    }
}

CommandA.java

@Command(
    name = "a",
    version = "${COMMAND-NAME} 1.0.0",
    description = "Command for action 'a'"
)
public class CommandA implements Runnable {
    @Override
    public void run() {
        // some command logic
    }
}

CommandB.java

@Command(
    name = "b",
    version = "${COMMAND-NAME} 1.0.0",
    description = "Command for action 'b'"
)
public class CommandB implements Runnable {
    @Override
    public void run() {
        // some command logic
    }
}

Result

BaseCommand.java

@CommandLine.Command(
    name = "tool",
    description = "My awesome tool",
    mixinStandardHelpOptions = true,
    subcommands = {CommandA.class,CommandB.class}
)
public class BaseCommand {
}
