1) org.codehaus.plexus:plexus-utils:jar:1.1

  Try downloading the file manually from the project website.

  Then, install it using the command: 
      mvn install:install-file -DgroupId=org.codehaus.plexus -DartifactId=plexus-utils -Dversion=1.1 -Dpackaging=jar -Dfile=/path/to/file

  Alternatively, if you host your own repository you can deploy the file there: 
      mvn deploy:deploy-file -DgroupId=org.codehaus.plexus -DartifactId=plexus-utils -Dversion=1.1 -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]

  Path to dependency:

I guess the reason for this error is, that http://repo1.maven.org/maven2 is used instead of https://repo1.maven.org/maven2 .
