为什么Apache Tomcat Maven插件会两次上传WAR文件？

Question

当我使用maven部署我的战争时，目标战争（完全相同）被上传到服务器两次。有人能解释一下吗？

我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

Answer 1

最近，我在将我的战争上传到测试服务器时遇到了同样的问题。我做了几次尝试在互联网上找到这个问题的答案，但都没有成功。偶然地，我在我的案例中发现了我们的问题，我在这里分享它，因为也许这可以帮助某人（但是，我不确定这是否是你的案例）。

所以在我的例子中，war的双重上传是由我转发端口的原因引起的。Tomcat通常在8080端口上工作。为了迫使它在80端口上工作，我配置了我的服务器（使用iptable），使它简单地将请求从80转发到8080端口。对于tomcat maven插件配置，我只是使用ip上传，而没有指定8080端口。这导致maven插件上传war两次（第一次请求是重定向，而第二次是实际上传）。

简单地将插件配置中的端口更改为8080就解决了我的问题。

试一试，运行mvn cmd行，但没有安装目标。
