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

             deleteFillFile(rootFile);
         }
     }

     }

     /**

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();
                         }
                     }
                 }
             }
         }
     }
