Eclipse WebApp 部署在 Maven 和 Tomcat 导致错误：“无法在上下文路径部署应用程序”

Question

当我尝试按照IBM Developerworks中的描述将我的HelloWorld项目部署到 Tomcat 7 和 Maven 3 时，使用命令mvn tomcat:deploy Failed to deploy application at context path /server

在列出的应用程序中，我的 /server 出现但无法启动。

I modified my maven web project according to the tutorial at base22 and applied the fix <url>http://localhost:8080/manager/html</url> for Tomcat 7 deployment in the pom.xml as descibet at loquatic .

命令：

mvn tomcat:deploy

错误：

[ERROR] Failed to execute goal org.codehaus.mojo:tomcat-maven-plugin:1.1:deploy (default-cli) on project server: Cannot
invoke Tomcat manager: FAIL - Failed to deploy application at context path /server -> [Help 1]

Tomcat tomcat-users.xml

<tomcat-users>
  <role rolename="admin-gui"/>
  <role rolename="manager-gui"/>
  <role rolename="manager"/>
  <role rolename="admin"/>
  <user username="admin" password="admin" roles="admin,manager,admin-gui,manager-gui"/>
</tomcat-users>

项目 web.xml

Answer 1

我得到这个错误，

  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

然后我将配置从mvn tomcat:deploy替换为mvn tomcat:redeploy

Answer 2

对于 Tomcat 7，您需要使用“文本”URL 进行部署。 这个 URL 是脚本用来部署的。 您正在尝试使用“gui”URL 进行部署。

设置方法如下：

tomcat-users.xml

<role rolename="manager-script"/>
<user password="script" roles="manager-script" username="script"/>

然后，在您的 pom.xml 中，您将 URL 设置为：“http://localhost:8080/manager/text/”

此外，在您的 maven settings.xml 中，将您的用户名/密码设置为脚本/脚本。

Answer 3

该应用程序已存在于该位置，您需要先取消部署它。

您可以先使用 tomcat 管理器或通过 maven 使用

mvn tomcat:undeploy

或使用以下命令：

mvn package tomcat:redeploy

覆盖当前实例。

Answer 4

tomcat maven 插件使用页面说

默认的 Tomcat 管理器 URL 是http://localhost:8080/manager 。

我认为您必须从配置中删除/html部分。
