在创建pom的jar包子集时遇到了该问题
在网上浏览了许多人的解决方案都是一样的
大多都建议清除掉maven\plugins\maven-deploy-plugin下的内容并在项目的maven里选择update project
但是我用这个方法并不好使
我在这里总结一下我的解决方案：

• 先核对Preference中maven的settings.xml文件的路径是否正确（这里我检查到我的路径错了）
• 再检查本地默认的repository路径是否有效（就是根据那个默认路径去看一眼是不是有这么个仓库）
• 之后清除掉maven\plugins\maven-deploy-plugin下的内容
• 注意！！如果你没有vpn，按照默认下载方式是没办法更新的，这里需要改一下maven仓库的下载地址，有vpn不需要考虑网络下载环境的可以忽略这一步。
• 关掉编译软件，再打开
• 打开后选择需要更新的那个项目，强制更新。

修改settings文件有截图和代码

最后成功下载好就更新完成了。
