-
Java 1.7
-
maven 3.0.5
-
mvn release：prepare; mvn release：perform;成功没有任何错误
-
mvn部署失败，返回码为500

这是我第一次将快照部署到远程存储库，因此nexus服务器上的快照存储库中没有任何内容

Nexus需要符合Servlet 3.0标准的容器 . 它捆绑了一个符合Servlet 3.0标准的Jetty 8.如果你将它部署在另一个容器上，你必须确保它是兼容的 . 无法在文件中找到这一点，但从自己的经验来看似乎是这样 .
当你
HTTP GET http://xxx.xxx.com:8080/nexus/content/repositories/snapshots/com/xxx/utils/licm/0.2.9-SNAPSHOT/maven-metadata.xml在浏览器中，您应该能够看到包含的堆栈跟踪
java.lang.NoSuchMethodError: javax.servlet.http.HttpServletResponse.getStatus()这仅适用于Servlet 3.0容器 .
自己回答 .
当nexus服务器找不到maven-metadata.xml时，会导致tomcat抛出异常，这就是问题所在
我将Tomcat版本从6.x更改为7.0.x，一切正常
我遇到了相同的返回码（500）和原因（内部服务器错误），并且finnaly发现nexus服务器磁盘空间已满 . :)检查服务器中的nexus日志可以找到这个线索 .
这是我报告的类似错误：
在我执行@hansi建议的http文件验证后，服务器响应为
javax.servlet.ServletException: java.lang.NumberFormatException: null.在对这是什么原因做了一些回顾之后，我发现这是因为工件创建时间戳的问题 . 在我的情况下，
maven-metadata.xml已损坏，这是由于服务器中的重新启动导致在夏令时完成后自动调整时间 . 我在这篇文章中得到了一个线索https://issues.sonatype.org/browse/NEXUS-12496在我的案例中有用的是删除所有工件引用中的
maven-metadata.xml. 之后，错误得到纠正 .在这里，我们失败了 .
正在下载：http://xxx.xxx.com:8080/nexus/content/repositories/snapshots/com/xxx/utils/licm/0.2.9-SNAPSHOT/maven-metadata.xml
然后我们无法获得该发布快照，因此我们手动将pom.xml文件更新为相关的依赖项详细信息然后它将起作用 .
