title: Maven - Error with building project
body: <p>I would like to give as good of description as possible but I have no really understanding of <code>Maven</code>. I was running my project, but unfortunately it is no longer working. </p>
  
  <p>Here is my error:</p>
  
  <blockquote>
    <p>[WARNING] For this reason, future Maven versions might no longer support building such malformed projects.</p>
    
    <p>[INFO] configuring report plugin org.apache.maven.plugins:maven-project-info-reports-plugin:3.0.0</p>
    
    <p>[WARNING] Error injecting: org.apache.maven.report.projectinfo.CiManagementReport
