两个月前把之前的nexus3迁移到另一台服务器后，当时看所有的jar包和snapshot包都在，就没有管了。今天在上传snapshot时报错如下：

Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy-file (default-cli) on project standalone-pom: Failed to retrieve remote metadata xxx:1.0.0-SNAPSHOT/maven-metadata.xml: Could not transfer metadata xxx1.0.0-SNAPSHOT/maven-metadata.xml from/to nexus-snapshots (http://xxxx/repository/maven-snapshots/): Failed to transfer file: http://xxxx/repository/maven-snapshots/xxx/1.0.0-SNAPSHOT/maven-metadata.xml. Return code is: 500 , ReasonPhrase:javax.servlet.ServletException: org.sonatype.nexus.repository.storage.RetryDeniedException: Reached max retries: 8/8.

看上面这个错误消息看不出是什么错误，搜索也基本上搜不出来，只是一个通用的retryDenied异常。

找到nexus日志sonatype-work/nexus3/log看了下，才看到真正的错误。如下：
