Maven无法解析依赖项，找不到依赖项，爆红

问题描述

使用pom.xml配置maven时无法解析依赖项依赖项爆红

---

原因分析：

我的setting镜像没有配置所以加了个镜像就好了

---

解决方案：

1右键点击maven，添加settings.xml

2.在<settings>标签中添加下面代码

<mirrors>
        <!-- mirror
         | Specifies a repository mirror site to use instead of a given repository. The repository that
         | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
         | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
         |-->
        <mirror>
            <id>nexus-aliyun</id>
            <mirrorOf>*,!jeecg,!jeecg-snapshots</mirrorOf>
            <name>Nexus aliyun</name>
            <url>http://maven.aliyun.com/nexus/content/groups/public</url>
        </mirror>

    </mirrors>

我的setting.xml的全部代码是 

<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
    <mirrors>
        <!-- mirror
         | Specifies a repository mirror site to use instead of a given repository. The repository that
         | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
         | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
         |-->
        <mirror>
            <id>nexus-aliyun</id>
            <mirrorOf>*,!jeecg,!jeecg-snapshots</mirrorOf>
            <name>Nexus aliyun</name>
            <url>http://maven.aliyun.com/nexus/content/groups/public</url>
        </mirror>

    </mirrors>
</settings>

 3.刷新一下下maven
