java使用cmd命令操作maven批量打包(并复制jar包到一个文件分类)

一、java类

                    System.out.println("文件:" + okJar.getAbsolutePath());
                    copyFileUsingFileChannels(jar, okJar);
                }

            }
            if (jarPaths.size() >= JAR_NUMBER) {
                break;
            } else {
                System.err.println("总计需要jar:" + JAR_NUMBER + ",已完成：" + okJarNumber + ",还差" + (JAR_NUMBER - okJarNumber));
                Thread.sleep(10000);
            }
        }
        System.err.println("----------------------------------打包完毕----------------------------------");
        System.err.println("路径：" + targetPath);
        System.err.println("----------------------------------打包完毕----------------------------------");
    }

    //判断是否已经复制
    private static boolean existsFile(File[] okJars, File jar) {
        for (File okJar : okJars) {
            if (okJar.getName().equals(jar.getName())) {
                return true;
            }
        }
        return false;
    }

    
    private static String createPathAdd(String path) {
        File file = new File(path);
        if (file.exists()) {
            int num = 1;

                if (file.exists()) {
                    num++;
                    newPath = path + "_" + num;
                } else {
                    break;
                }
            }
            file.mkdir();
            path = newPath;
        } else {
            file.mkdir();
        }
        return path;
    }

    
    private static String createPath(String path) {
        File file = new File(path);
        if (!file.exists()) {
            file.mkdir();
        }
        return path;
    }

    
    private static void traverseFolder(List paths, String path) {
        File file = new File(path);
        if (file.exists()) {
            File[] files = file.listFiles();
            if (files.length == 0) {
                return;
            } else {
                for (File file2 : files) {
                    if (file2.isDirectory()) {
                        traverseFolder(paths, file2.getAbsolutePath());
                    } else {
                        if (file2.getAbsolutePath().endsWith(".jar") && !file2.getAbsolutePath().endsWith("SNAPSHOT.jar") && !file2.getAbsolutePath().endsWith("sources.jar")) {
                            long fileTime = file2.lastModified();
                            long nowTime = new Date().getTime();
                            if ((nowTime - fileTime) <= LAST_TIME) {
                                paths.add(file2.getAbsolutePath());
                            }
                        }
                    }
                }
            }
        }
    }

    
    private static void copyFileUsingFileChannels(File source, File dest)
            throws IOException {
        FileChannel inputChannel = null;
        FileChannel outputChannel = null;
        try {
            inputChannel = new FileInputStream(source).getChannel();
            outputChannel = new FileOutputStream(dest).getChannel();
            outputChannel.transferFrom(inputChannel, 0, inputChannel.size());
        } finally {
            inputChannel.close();
            outputChannel.close();
        }
    }
}
//使用cmd命令操作maven打包(多线程执行)
class PackageCmdThread extends Thread {
    private String cmd;

    public PackageCmdThread(String cmd) {
        this.cmd = cmd;
    }

    @SneakyThrows
    @Override
    public void run() {
        Runtime run = Runtime.getRuntime();
        Process p = run.exec(cmd);
        InputStream inputStream = p.getInputStream();
        BufferedReader br = new BufferedReader(new InputStreamReader(inputStream, "gb2312"));
        String line = null;
        while ((line = br.readLine()) != null) {
            System.out.println(line);
        }
    }
}

二、cmd打包命令

cmd /k cd D:lmphwaseesourcehealth_mhs_packagehwasee-health-mhs && mvn clean package -Dmaven.test.skip=true

cmd /k
cmd /c ：是执行完dir命令后关闭命令窗口；
cmd /k ：是执行完dir命令后不关闭命令窗口。

D:lmphwaseesourcehealth_mhs_packagehwasee-health-mhs && mvn clean package -Dmaven.test.skip=true
多个命令使用&&连接

三、多线程执行cmd命令代码

    public static void main(String[] args) {
        //异步打包
        for(String cmd : packageCmds){
            Thread t = new PackageCmdThread(cmd);
            t.start();
        }
    }

//使用cmd命令操作maven打包(多线程执行)
class PackageCmdThread extends Thread {
    private String cmd;

    public PackageCmdThread(String cmd) {
        this.cmd = cmd;
    }

    @SneakyThrows
    @Override
    public void run() {
        Runtime run = Runtime.getRuntime();
        Process p = run.exec(cmd);
        InputStream inputStream = p.getInputStream();
        BufferedReader br = new BufferedReader(new InputStreamReader(inputStream, "gb2312"));
        String line = null;
        while ((line = br.readLine()) != null) {
            System.out.println(line);
        }
    }
}
