为什么插件两次上传WAR文件？

Question

当我使用maven部署WAR时，目标war (完全相同的war)将被两次上传到服务器。有人能解释一下吗？

我正在我的模块上使用这个：

clean install org.apache.tomcat.maven:tomcat6-maven-plugin:2.0:redeploy 

从日志文件中

Answer 1

试一试，在没有安装目标的情况下运行mvn行。

Answer 2

最近，在将war上传到测试服务器时，我遇到了同样的问题。我曾多次尝试在互联网上找到这个问题的答案，但都没有成功。无意中，我发现了我的问题，我在这里分享它，因为也许这可以帮助某人(但，我不确定这是否是你的情况)。

所以在我的例子中，war的双重上传是因为我转发了端口。Tomcat通常工作在8080端口上。为了迫使它在80个端口上工作，我配置了我的服务器(使用iptables)，使其只需将请求从80端口转发到8080端口。对于tomcat maven插件配置，我只使用了ip上传，而没有指定8080端口。这会导致maven插件上传war两次(第一个请求是重定向，第二个请求是实际上传)。

简单地将插件配置中的端口更改为8080解决了我的问题。
