=================================================二更================================================================
可算搞好了，除了下面外，我找到了setting.xml里面的东西，给出来就好了，简单就是mvn -v弄好后，setting.xml里面写好的话，直接加入，然后让eclipse下载jar包
然后就可以运行网上的基本项目了

Profiles provided in the settings.xml are intended to provide local machine- 173 | specific paths and repository locations which allow the build to work in the local environment. 174 | 175 | For example, if you have an integration testing plugin - like cactus - that needs to know where 176 | your Tomcat instance is installed, you can provide a variable here such that the variable is 177 | dereferenced during the build process to configure the cactus plugin. 178 | 179 | As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles 180 | section of this document (settings.xml) - will be discussed later. Another way essentially 181 | relies on the detection of a system property, either matching a particular value for the property, 182 | or merely testing its existence. Profiles can also be activated by JDK version prefix, where a 183 | value of '1.4' might activate a profile when the build is executed on a JDK version of '1.4.2_07'. 184 | Finally, the list of active profiles can be specified directly from the command line. 185 | 186 | NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact 187 | repositories, plugin repositories, and free-form properties to be used as configuration 188 | variables for plugins in the POM. 189 | 190 |--> 191 <profiles> 192 <!-- profile 193 | Specifies a set of introductions to the build process, to be activated using one or more of the 194 | mechanisms described above. For inheritance purposes, and to activate profiles via <activatedProfiles/> 195 | or the command line, profiles have to have an ID that is unique. 196 | 197 | An encouraged best practice for profile identification is to use a consistent naming convention 198 | for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc. 199 | This will make it more intuitive to understand what the set of introduced profiles is attempting 200 | to accomplish, particularly when you only have a list of profile id's for debug. 201 | 202 | This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo. 203 <profile> 204 <id>jdk-1.4</id> 205 206 <activation> 207 <jdk>1.4</jdk> 208 </activation> 209 210 <repositories> 211 <repository> 212 <id>jdk14</id> 213 <name>Repository for JDK 1.4 builds</name> 214 <url>http://www.myhost.com/maven/jdk14</url> 215 <layout>default</layout> 216 <snapshotPolicy>always</snapshotPolicy> 217 </repository> 218 </repositories> 219 </profile> 220 --> 221 222 <!-- 223 | Here is another profile, activated by the system property 'target-env' with a value of 'dev', 224 | which provides a specific path to the Tomcat instance.

当然，如果你用一些什么注释的话，pom.xml里面也要写好，我也给出来吧，基本都可以用，目前用lombok,shiro,thymeleaf什么的都还没遇到错误

前提：简单记录下这2天配置Maven环境遇到的问题
环境：
jdk1.08
Maven3.6.0
eclipse
网上有一大堆讲解，我就不重复了，简单说一下mvn -v弄好后再遇到的问题。
第一步：mvn -v:(验证配置成功入下图)
遇到的第一个问题 (mvn -v一直失败)：
解决方案：按道理按照网上步骤不会出错，但是最终发现jdk错误，我之前用的jdk1.6,实际是1.8
下面也又相关视频配置
慕课网 https://www.imooc.com/learn/443
mvn -v成功后打开eclipse中pom.xml一直报错，也明白了maven没有完全配置好。
步骤二：将setting.xml加入路径（如何加入网上也有讲解,如果每次更改setting.xml，除了重新导入setting.xml外，还需要重启eclipse,在Maven Repositories里面的Global Repositories可以检测mirrors是否更新了）
遇到的第二个问题：
CoreException: Could not calculate build plan: Plugin org.apache.maven.plugins:maven-compiler-plugin
解决方案：settings.xml里面profiles没有写好,写好后去你的mirrors里面的repository里面查看jar包，重新下载，具体见如下博客
https://blog.csdn.net/u010452388/article/details/80789816
（我当时是将2.6删除了，然后再建立项目就相当于重新下载，然后就好了）
疑点：settings.xml里面需要修改的就是profiles和mirrors),mirrors按照网上说要改成aliyun或者别的，但是我弄了很多方案也还是Rebuild Index搞不好，不知道为什么，先给出来。

步骤三：继续报错
Could not resolve archetype org.apache.maven.archetypes:maven-archetype-webapp:1.0 from any of the configured repositories.
解决方案：
https://www.cnblogs.com/rever/p/7076596.html
我用的最后一个补充的方法，打开CMD即可，不用在意路径.jar包下载完
步骤四：eclipse不再报错，新建Maven project也不再报错，新建项目如下面博客
https://www.cnblogs.com/lzx2509254166/p/7674455.html
我重新测试了一下,pom.xml里面没更改，什么都没变，一建立就能运行了，eclipse的Console窗口显示如下，建立Maven project即可，什么代码都不用加，然后项目没有红叉叉
总结：总体配置Maven环境过程如下:
1.mvn -v 成功
2.加入setting.xml(里面的东西写好)
3.新建Maven项目不报错(然后就算成功？网上也没看到什么附加内容，就算成功了吧，开始写springbboott项目)
疑点：mirrors那一块我试了各种mirror也没有成功Rebuild Index成功，看网上说这个功能是为了找jar包方便，对我用处目前不算特别大，先留下来吧。
