使用 JeecgBoot Maven 依赖包无法下载 异常 The following artifacts could not be resolve

本文已参与「新人创作礼」活动，一起开启掘金创作之路。

最近公司接了二次外包项目，项目是使用 JeecgBoot （doc.jeecg.com/） 搭建的，第一次导入项目怎么都不成功，报了如下错误。

[ERROR] Failed to execute goal on project xxx-base-core: Could not resolve dependencies 
for project org.dekunframework.boot:xxxx-base-core:jar:2.4.0: The following artifacts 
could not be resolved: org.hibernate:hibernate-re:jar:2.3.07, 
org.jeecgframework.boot:codegenerate:jar:1.2.5: Cannot access nexus-aliyun 
(http://maven.aliyun.com/nexus/content/groups/public) in offline mode and the artifact 
org.hibernate:hibernate-re:jar:2.3.07 has not been downloaded from it before. -> [Help 1]

最后处理方法是我本地用的[maven]需要使用mirrorOf排除掉jeecg；

原配置：

<mirror> 
    <id>nexus-aliyun</id>
    <name>Nexus aliyun</name> 
    <url>http://maven.aliyun.com/nexus/content/groups/public</url>
</mirror>

需要添加配置：

<mirrorOf>*,!jeecg,!jeecg-snapshots</mirrorOf>

修改后配置：

<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>
