Iterate over each dependency: [#foreach dependency in project.dependencies.dependency] of each pom.xml: [#foreach project in xmlset.project]

@startuml

[#foreach project in xmlset.project]
artifact ${project.artifactId}
  [#foreach dependency in project.dependencies.dependency]
    [#assign deps = dependency.artifactId?replace('.','_')?replace('-','_')]
artifact ${deps}
${project.artifactId} --* ${deps}
