我想从eclipse中的maven上传部署的war文件到nexus OSS，但是我得到一个错误信息。

Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy (default-deploy) on project xxx: Failed to deploy artifacts: Could not transfer artifact com.xxx.xxx:xxx:war:5.2.0 from/to nexus (http://xxx.xxx.xxx.xxx:8081/repository/maven-releases/): Access denied to http://xxx.xxx.xxx.xxx:8081/repository/maven-releases/com/xxx/xxx/xxx/5.2.0/xxx-5.2.0.war. Error code 401, Unauthorized -> [Help 1]

使用相同的配置(pom.xml 和 settings.xml)我部署了一个 jar 文件并且它可以工作。

两者的区别在于文件类型和文件大小。 一个是80mb的war文件，一个是400kb的jar文件。

有没有人有想法，如何解决这个问题？有没有配置，我想念的那些？这不是 1 周前发生的。我什么都不改，只把2019年的eclipse版本更新到2020年。

谢谢

最佳答案

我遇到了同样的问题，并且困惑了好几个星期。我发现这个问题是从 Eclipse 版本 202003 开始​​出现的。使用与 V201912 相同的配置或仅使用 CMD 部署就可以了。

我觉得是eclipse内嵌Maven的问题；

• 在 V201912 中是 3.6.3/1.14.0.20191209-1923
• 在 V202006 中是 3.6.3/1.16.0.20200610-1735。

在 V202006 中更改为使用最近的外部 Maven Artifact 3.6.3 是可以的。因此，由于我有几十个工作区，所以我现在只能使用 V201912。

eclipse-202009需要java11，不再支持java8，所以，我们就永远忍受这个问题吧？
