? ? ? ? 介绍：公司内部会制定自己的规范及包结构。当创建新项目的时候就需要选择骨架，即可生成包结构。本文章简单介绍如何创建，解决遇到的各种问题。
一、创建项目。
?idea点击file--->new--->project--->点击左侧的Spring initializr-
图2??
创建自己的各种包，及配置。包括pom.xml；yml；?
二、命令生成骨架
根目录执行mvn archetype:create-from-project
如图所示：
执行正常结果图
?
?
再进入target\generated-sources\archetype?这个目录执行：mvn clean install；就把骨架安装到仓库中了。
?
其他人用这个骨架，就可以把仓库文件复制过去。使用?
如果执行第一步失败；见问题处理。
三、选择骨架，创建新项目
?idea点击file--->new--->project--->点击左侧的Maven----->选中复选框create from archetype----->选择自己的骨架。填写包路径，项目名称就可以了
?
如果不展示自己的骨架，见问题处理
四、遇到的问题
错误1.执行mvn archetype:create-from-project命令失败；如图

?这个是说找不到setting.xml，我的maven配置已经是我自己的了，不知道为什么这里又走别处了，没有找到解决办法，只能复制一份setting.xml放在这个目录C:\Users\admin\.m2下；如图：
在运行就解决了。
?错误2. 骨架生成了，仓库也有但是自己创建的时候不显示
解决办法：在C:\Users\admin\AppData\Local\JetBrains\IntelliJIdea2021.2\Maven\Indices这个目录下面自己新建一个UserArchetypes.xml；填写内容：
<archetypes>
<archetype groupId="com.example" artifactId="demo-archetype" version="0.0.1-SNAPSHOT" />
</archetypes>重启idea就可以看见了。
错误3：自己新建项目，出现wrapper
错误图：
?
这是因为选择spring Initializr?创建项目有多余的文件生成，需要删除。再重新生成骨架；删除图中文件
?
