For Tomcat 7 you need to deploy with the "text" URL. This URL is what is used by scripts to deploy. You are trying to deploy with the "gui" URL.
对于 Tomcat 7，您需要使用“文本”URL 进行部署。此 URL 是脚本用于部署的 URL。您正在尝试使用“gui” URL 进行部署。
Here's how to set it up:
设置方法如下：
tomcat-users.xml
tomcat-users.xml
<role rolename="manager-script"/>
<user password="script" roles="manager-script" username="script"/>
Then, in your pom.xml you set the URL to be: "http://localhost:8080/manager/text/"
然后，在 pom.xml 中将 URL 设置为：“http://localhost:8080/manager/text/”
Also, in your maven settings.xml, set your username/password to be script/script.
此外，在您的 maven settings.xml 中，将您的用户名/密码设置为脚本/脚本。

I get this error,
我收到这个错误，
Failed to execute goal org.codehaus.mojo:tomcat-maven-plugin:1.1:deploy (default-cli) on project projectname:
Cannot invoke Tomcat manager: FAIL - Application already exists at path /path
Then I replaced the configuration from mvn tomcat:deployto mvn tomcat:redeploy
然后我将配置从mvn tomcat:deploy到mvn tomcat:redeploy
回答by Tnem
The application already exists at that location, you need to undeploy it first.
该应用程序已存在于该位置，您需要先取消部署它。
You can either undeploy it first using the tomcat manager or through maven using
您可以先使用 tomcat 管理器或通过 maven 取消部署它
mvn tomcat:undeploy
or use the following command:
或使用以下命令：
mvn package tomcat:redeploy
to write over the current instance.
覆盖当前实例。

The tomcat maven plugin usagepage says that
tomcat maven 插件使用页面说
The default Tomcat manager URL is http://localhost:8080/manager.
默认的 Tomcat 管理器 URL 是http://localhost:8080/manager。
I think you have to remove the /htmlpart from your configuration.
我认为您必须/html从配置中删除该部分。
