如何在控制台[复制]中运行带有公共cli的java应用程序

Question

我有maven项目，我正在尝试使用Commons cli库来处理输入数据：

import org.apache.commons.cli.*;
import java.util.logging.Level;
import java.util.logging.Logger;

public class Cli {
    private static final Logger log = Logger.getLogger(Cli.class.getName());
    private String[] args = null;
    private Options options = new Options();

    public Cli(String[] args) {

        this.args = args;

        options.addOption("h", "help", false, "show help.");
        options.addOption("i", "inputs", true, "Enter the input file name.");
        options.addOption("o", "output", true, "Enter the output file name.");
    }

    public String[] parse() {
        CommandLineParser parser = new BasicParser();
        String[] returnArguments = new String[2];
        CommandLine cmd = null;
        try {
            cmd = parser.parse(options, args);

            if (cmd.hasOption("h"))
                help();

            if (cmd.hasOption("i")) {
                log.log(Level.INFO, "The initial file will be " + cmd.getOptionValue("i"));
                returnArguments[0] = cmd.getOptionValue("i");
            } else {
                log.log(Level.SEVERE, "Missing input file name option");
                help();
            }

            if (cmd.hasOption("o")) {
                log.log(Level.INFO, "The output file will be " + cmd.getOptionValue("o"));
                returnArguments[1] = cmd.getOptionValue("o");
            } else {
                log.log(Level.SEVERE, "Missing output file name option");
                help();
            }
        } catch (ParseException e) {
            log.log(Level.SEVERE, "Failed to parse command line properties", e);
            help();
        }
        return returnArguments;
    }

    private void help() {
        HelpFormatter formatter = new HelpFormatter();
        formatter.printHelp("Main", options);
        System.exit(0);
    }
}

我在Intellij Idea中设置参数：-iinputs.zip-ooutput.zip它可以工作，但是我应该在控制台中使用什么命令？

我试过：java-jar NewMyZip-1。jar-i输入。zip-o输出。zip得到了一个例外：

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/cl
i/ParseException
        at main.MyZip.main(MyZip.java:12)

有人知道问题是什么以及如何解决吗？

Answer 1

这是你的新ZIP-1。包含commons cli的jar？否则，请确保在类路径中包含commons cli jar：

java -cp PATH_TO_JAR/commons-cli.jar -jar NewMyZip-1.jar -i inputs.zip -o output.zip
