tomcat7 maven plugin deploy fails

Question

I am having trouble in deploying to remote machine with tomcat installed as aservice. My tomcat-users is as follows:

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

</tomcat-users>

My settings.xml is:

<settings>
<pluginGroups>
<pluginGroup>org.apache.tomcat.maven</pluginGroup>
</pluginGroups>
<servers>
<server>
  <id>tomcat7</id>
  <username>admin</username>
  <password>admin</password>
</server>

</servers>

</settings>

And my pom.xml has the following:

            <plugin>
                <groupId>org.apache.tomcat.maven</groupId>
                <artifactId>tomcat7-maven-plugin</artifactId>
                <configuration>
                    <server>tomcat7</server>
                    <url>http://localhost:8081/manager/text</url>
                    <warFile>target/editor-${project.version}.war</warFile>
                </configuration>

And I keep on getting the 401 Unauthorized on the output of maven console. Can you tell me what am I doing wrong?

The following way works for me.

1. Please change your pom.xml to include

   <project>
       ...
       <build>    
           <plugins>    
           ....
               <plugin>
                   <groupId>org.apache.tomcat.maven</groupId>
                   <artifactId>tomcat7-maven-plugin</artifactId>
                   <version>2.1</version>
                   <configuration>
                       <url>http://localhost:8080/manager/text</url>
                       <server>my-tomcat</server>
                       <path>/myapp</path>
                   </configuration>
               </plugin>
           </plugins>
           ...
       </build>
       ...
   </project>
   

2. Make sure your Tomcat 7 server have the following lines on TOMCAT_HOME/conf/tomcat-users.xml:

   <!-- Role to manage WAR files via HTML /manager. The name should be as is! -->
   <role rolename="manager-gui"/>
   <!-- Role to manage WAR files via script like Maven. The name should be as is! -->
   <role rolename="manager-script"/>
   
   <!-- One user cannot have manager-gui and manager-script roles -->
   <user username="managerGui" password="managerPwd" roles="manager-gui"/>
   <user username="manager" password="managerPwd" roles="manager-script"/>
   

3. Configure your USER_HOME/.m2/settings.xml to include the password.

   <settings>
       ...
       <servers>
           ...
           <server>
               <id>my-tomcat</id>
               <username>manager</username>
               <password>managerPwd</password>
           </server>
       </servers>
   
   </settings>
   

4. Deploy using mvn tomcat7:redeploy
