PomPlugin extension container. Not used as extension (project.extensions), but as convention (project.conventions) because actual closure is structure free may define any pom sections (free xml).

Example usage:

 
     pom {
         licenses {
              license {
                  name "The MIT License"
              }
         }
         developers {
             developer {
                 id "dev1"
                 name "Dev1 Name"
                 email "dev1@email.com"
             }
         }
     }
 
 
 Only one pom configuration may be defined: if multiple pom configurations defined, only the last one will be
 applied
 

 If manual pom modification is required:
 

     withPomXml {
         it.appendNode('description', 'A demonstration of maven POM customization')
     }
 
 withPomXml convention usage is equivalent to maven-publish plugin withXml closure, but without need to call
 asNode() because node is already provided as parameter.
