idea自定义archetype及错误处理

        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：

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
