我有maven project并从中生成war个文件。我想将此工件发布到Nexus Oss。我编辑了pom文件以及/root/.m2/settings.xml文件，但仍然没有上传文件并引发以下错误
"Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy (default-deploy) on project CustomerOnBoard: Failed to deploy artifacts: Could not transfer artifact CustomerOnBoard:CustomerOnBoard:war:1.1.43-20170221.110417-1 from/to nexus (http://ceala04987.emea.zurich.corp:8081/repository/cob1/): Broken pipe"
Nexus中的存储库是cob。我们确实在设置文件中配置了代理。
