Java 无法调用Tomcat管理器：服务器返回HTTP响应代码：401

我试图从maven将war部署到远程tomcat服务器，但在NetBeans中出现以下错误：

Failed to execute goal org.codehaus.mojo:tomcat-maven-plugin:1.1:deploy (default-cli)
on project noca: Cannot invoke Tomcat manager:
Server returned HTTP response code: 401 for URL:
http://12.34.56.78/manager/html/deploy?path=%2Fnoca&war= -> [Help 1]

我觉得奇怪的是，

war

没有价值，我也不知道为什么

当我浏览此URL时，我在Tomcat的管理器中得到以下内容：

FAIL - Invalid context path null was specified

这是我的

pom.xml

尝试让用户控制tomcat和部署，这很简单，也很有效。

我在博客上写了一篇文章，解释如何使用cargo:@JVerstry现在我使用简单的bash脚本，如下所示：它对jenkins更有用，帮助我在重新部署地狱时逃离permgen。我希望你也会喜欢：）
