Question

i am learning tomcat basics and while i tried to deploy my web-application on tomcat i am getting the following error

[ERROR] Failed to execute goal org.codehaus.mojo:tomcat-maven-plugin:1.1:deploy (default-cli) on project struts2-demoapp: Cannot invoke Tomcat manager: Server returned HTTP response code: 401 for URL: http://localhost:8080/manager/html/deploy?path=%2FmkyWebApp&war= -> [Help 1]
[ERROR]

as per this it seems war file location is not being passed to the tomcat manager.i have the following entries in my tomcat-user.xml

tomcat-users>
<user name="admin" password="admin" roles="admin,manager" /><!--
  NOTE:  The sample user and role entries below are wrapped in a comment
  and thus are ignored when reading this file. Do not forget to remove
  <!.. ..> that surrounds them.
-->

<role rolename="manager"/>
  <role rolename="admin"/>
  <user username="admin" password="admin" roles="admin,manager"/>


</tomcat-users>

here are the details of the pom.xml

<build>
        <plugins>
        <plugin>
                <artifactId>maven-war-plugin</artifactId>
                <version>2.1.1</version>
                <configuration>
                    <packagingExcludes>WEB-INF/web.xml</packagingExcludes>
                </configuration>
            </plugin>
            <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>tomcat-maven-plugin</artifactId>
        <configuration>
                <warFile>${project.build.directory}/${project.build.finalName}.war</warFile>
                <url>http://localhost:8080/manager/html</url>
                <server>myserver</server>
                <path>/mkyWebApp</path>

        </configuration>
</plugin>

        </plugins>
    </build>

in my setting.xml there are the entries

<server>
      <id>Tomcat6.x</id>

      <username>admin</username>
      <password>admin</password>
    </server>

i am not sure what exactly is going wrong here.any help in this regard will be helpful.

Answer 1

You need to map the credentials from your settings.xml to the server configuration at your pom.xml.

In your case, this is done but setting the <id> element of your server, to match the server’s host name from the pom.xml.

Since you are pointing localhost, the id must be also localhost.
When you change the hostname, you must also update settings.xml.
