maven学习之路三
我们在写代码的时候，有些项目会有重复代码，或者是重复项目结构，这样我们就可以用maven 生成一个项目的基本骨架，就像我之前介绍的哪个logindemo一样继承了webApp-achetype一样。我们也可以生成我们自己的项目骨架。
准备下我们的项目骨架结构：看图：
看下我这边的已有的代码：
我的这个程序是一个普通http接口。然后往往在公司会有很多这样的接口，然后每个接口都去实现同样的一份代码程序会感觉很费时间，包括拷贝代码建立项目目录等，都会很花费时间的，通用的代码可以做成jar 被依赖继承，但是那些不通用的地方就需要自己实现了，但是自己实现的项目结构往往是一样的，这样就可以用到这个骨架了。
来看下我这pom.xml文件：

project>这里面别的我就不介绍了，主要讲下这段配置

<snapshotRepository>

distributionManagement>这里主要是deploy和install用到个人私服仓库，这里会指定你上传到哪里的url 。我的url在maven 配置settings文件里面配置了，所以这里只要用${引用就可以了}；
如果没有settings.xml中没有配置就需要这样配置了：
<repositories>
<repository>
<id>local-nexusid>
<name>private repository nexusname>
<url>http://xxx:8081/nexus/content/groups/public/url>

distributionManagement>step 2 ：接下来就是生成这个项目骨架了
- cmd到项目目录，mvn clean，然后 mvn archetype:create-from-project
- 成功之后cd到target/generated-sources/archetype， mvn clean compile
然后查看下这个目录下有什么东西
3.然后检查下target/generated-sources/archetype这个目录下这pom.xml文件
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

如果此时mvn deploy 的化会出现Error 如下图
并没有下面这个：
<distributionManagement>
<repository>
<id>nnk-releasesid>
<name>NNK Releases Repositoryname>
<url>${repositories.releases.url}url>
repository>
<snapshotRepository>

distributionManagement>这时就需要在pom.xml里面加上这段：

project>然后再 mvn deploy 之后就把这个骨架上传到我们的私服仓库了。
step 3：怎么使用这个骨架
我新建一个项目：
点击ok 然后:
之后的步骤就不多介绍了和前面logindemo的步骤是一样的。
最终生成的项目结构就是这样子的：
这样我们的项目结构骨架就是这样生成了，这样只需要在项目骨架上面做开发了，是不是会爽很多，
有什么不懂得地方欢迎和我交流，
