Tomcat-Maven 401 Error: Cannot invoke Tomcat manager

Went through most of the errors shown in StackOverFlow and still couldn't solve it. I'm trying to deploy a SpringMVC application. But, I just can't get it to work.

Maven Deploy Error:

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

Tomcat-Users.xml

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

This worked for me

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

Solution

Your maven configuration has the username and password set as admin/password. In the Tomcat configuration they are set as admin/admin.

Switch your pom.xml to have <password>admin</password>.

Also, the roles need changing for the admin user as per the Tomcat docs. You'll want the manager-gui role to access the HTML manager and the manager-script role to access the text interface.
