解决Git无法同步空文件夹的问题

思路：在每个空文件夹下创建空文件，同步后再删除

package org.zln.module1.demo1;

        String delFlag;
        if (null == args||args.length != 2){

        }else {
            rootDir = args[0];
            delFlag = args[1];
        }
        logger.debug("对目录："+rootDir+" 进行"+(createFlag.equals(delFlag)?"创建":"删除"));

            createFileInEmptyDir(rootFile);
        }else {//删除
            deleteFillFile(rootFile);
        }
    }

    /**
     * 在跟路径下,遍历所有的目录,如果该目录为空,则创建一个文件

     */

                createTxtFile(rootFile,fillFileName);
                logger.debug(rootFile.getAbsolutePath()+"\t为空目录,创建填充文件");

            }else {
                for (int i = 0; i < listFiles.length; i++) {

        newFile.createNewFile();
    }

    /**
     * 删除指定目录下的填充文件
     * @param root
     */
    private static void deleteFillFile(File root){
        if (root.isDirectory()){//是目录
            File[] files = root.listFiles();
            for (File tempFile:files){
                deleteFillFile(tempFile);
            }
        }else {//是文件
            String fileName = root.getName();
            if (fillFileName.equals(fileName)){

依赖jar包

执行脚本：

#进入执行目录 - 程序根目录
cd E:\GitHub\tools\JavaEEDevelop\out\production\Lesson1_JavaSe_Demo1

#设置class路径
set CLASSSERVER_HOME=E:\GitHub\tools\JavaEEDevelop\GlobalLib

set CLASSPATH=.

set CLASSPATH=%CLASSPATH%;%CLASSSERVER_HOME%\log4j\log4j-1.2.17.jar

set CLASSPATH=%CLASSPATH%;%CLASSSERVER_HOME%\log4j\log4j-api-2.2.jar

set CLASSPATH=%CLASSPATH%;%CLASSSERVER_HOME%\log4j\log4j-core-2.2.jar

#根据需求执行指令
#对指定目录及其子目录的空文件夹创建空文件
java  org.zln.module1.demo1.CreateFileInEmptyDir E:\GitHub\tools\JavaEEDevelop create
#删除创建的空文件
java  org.zln.module1.demo1.CreateFileInEmptyDir E:\GitHub\tools\JavaEEDevelop delete

 

日志配置：

优化：创建与删除可以同时进行

添加一个方法

/**
     * 创建或删除空文件在指定路径及其子路径下
     * @param rootFile 根路径
     */
    private static void createOrDeleteFile(File rootFile) throws IOException {
        if (rootFile.isDirectory()){
            File[] listFiles = rootFile.listFiles();
            if (0 == listFiles.length){
                createTxtFile(rootFile,fillFileName);
                logger.debug(rootFile.getAbsolutePath()+"\t为空目录,创建填充文件");
            }else if (1 < listFiles.length){
                for (File temp:listFiles){
                    if (temp.isDirectory()){
                        createOrDeleteFile(temp);
                    }else {
                        if (fillFileName.equals(temp.getName())){
                            logger.debug("填充文件失效，删除:"+temp.getAbsolutePath());
                            temp.delete();
                        }
                    }
                }
            }
        }
    }
