How to configure "tomcat7-maven-plugin" in pom.xml?

Question

I am trying to add a tomcat7-maven-plugin dependency to pom.xml file and getting an error. I am following the instructions on tomcat.apache.org.

cvc-complex-type.2.4.a: Invalid content was found starting with element 'configuration'. One of '{"http://maven.apache.org/POM/4.0.0":type, "http://
 maven.apache.org/POM/4.0.0":classifier, "http://maven.apache.org/POM/4.0.0":scope, "http://maven.apache.org/POM/4.0.0":systemPath, "http://
 maven.apache.org/POM/4.0.0":exclusions, "http://maven.apache.org/POM/4.0.0":optional}' is expected.

My full pom.xml config

Answer 1

The Tomcat7-maven-plugin should be declared as a plugin, it is not a dependency. You can't add a configuration tag to a dependency as indicated by the error.

Thus something like the following should work :

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
