读取所有项目的git地址和分支并写入文件的工具

Posted 2021-10-11 阿拉的梦想

离职要交接工作，负责的项目较多，项目工程有200多个，每个都是单独的git地址，分支也不尽相同。

领导要求将全部项目的git地址和分支整理出来，一个个点击复制，相当麻烦，因此写了这个小工具，可以全部扫描出来，并写入到指定的gitUrl.txt中。

package com.demo.gittool;

        if (gitUrlFile.exists()) {
            gitUrlFile.delete();
        }
        gitUrlFile.createNewFile();
        visitFile(rootPath);

                if (pathStr.endsWith(".git\\\\config")) {
