本地搭建start.spring.io

 内网或者网络不好的时候就无法使用start.spring.io 新建springboot项目了，所有就自己搭建本地的服务器吧。

• 使用git cloen代码：git clone https://github.com/spring-io/start.spring.io.git

• 打包编译：cd start.spring.io ，执行./mvnw clean package -Dmaven.test.skip=true

• 进入start-site arget目录下两个jar包 用start-site-exec.jar可以， 使用java -jar -Dserver.port=8080 start-site-exec.jar 运行

• IDEA之中，使用Custom，填入localhost:8080然后创建项目

解决办法：

　　很明显了，仔细看一下错误信息就能解决！！ 其实最后给了解决办法了“ Run `spring-javaformat:apply` to fix. ”！

因为这个工程使用的是mvnw ，所以运行一下命令解决此问题。

$  ./mvnw spring-javaformat:apply

 ERROR2：

   maven git插件找不到.git目录的问题！！

解决办法：

       不知道在github上下载的官方源码为啥会有问题！！既然错误信息里说了“未找到git目录！”  ,那解决办法有两种：1，给他配置目录  2，跳过执行该目标;    建议新手小白使用第二种,,,我就是使用第二种,,,言归正传，第二种解决办法如下：

找到你想项目->  github源码根目录start-sitepom.xml -->编辑此文件  -->搜索“git-commit-id-plugin”  -->新增以下北京黄色部分代码

<plugin>
    <groupId>pl.project13.maven</groupId>
    <artifactId>git-commit-id-plugin</artifactId>
    <configuration>
        <!--".git"文件夹未找到时,构建是否失败;若设置true,则构建失败;若设置false,则跳过执行该目标;默认值:true;-->
        <failOnNoGitDirectory>false</failOnNoGitDirectory>
    </configuration>
</plugin>

 1.使用./mvnw **  命令下载资源太慢？？

解决办法：

       首先你的明白mvnw跟mvn命令的区别，推荐看下这篇博客：https://blog.csdn.net/Fishandbearspaw/article/details/104637284/  简单明了 适合新手！

看完博客之后呢？？我们去修改他的这个命令maven的配置文件：

C:Users登录名.m2wrapperdistsapache-maven-你的版本号-bin1iopthnavndlasol9gbrbg6bf2apache-maven-你的版本号confsettings.xml

例如我的：

C:UsersAdministrator.m2wrapperdistsapache-maven-3.6.3-bin1iopthnavndlasol9gbrbg6bf2apache-maven-3.6.3confsettings.xml

 其实就是修改mirrors 指定去aliyun下载！！
