解决maven拉取不到snapshot jar, settings.xml配置

POM.xml文件里更改了version，发现jar包拉不下来，一直报错，看了仓库是有这个jar的，开始看我的maven配置文件，发现是配置了不拉取快照版本的jar

maven的setting.xml配置：

<settings xmlns="http://maven.apache.org/SETTINGS/1.2.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.2.0 https://maven.apache.org/xsd/settings-1.2.0.xsd">

< enabled>true
true或者false表示该仓库是否为下载某种类型构件（发布版，快照版）开启。

< snapshots>
< enabled>true
fail

 <snapshots>
<enabled>trueenabled>
<checksumPolicy>failchecksumPolicy>
snapshots>

看了一下，是snapshots配置问题fail代表失败，改为warn就好了
ignore（忽略），fail（失败），或者warn（警告）。
