title: Zip old builds in jenkins plugin
body: <p>There is some Jenkins plugin to ZIP old builds? I don't want to package just the generated archive (I am deleting those). I want to ZIP just the log data and the data used by tools, like FindBugs, Checkstyle, Surefire, Cobertura, etc.</p>
  
  <p>Currently I am running out of disk space due to Jenkins. There are some build log files that reach 50 Mb due running 3000+ unit tests (most of these are severely broken builds full of stacktraces in which everything fails). But this happens frequently in some of my projects, so I get this for every bad build. Good builds are milder and may get up to around 15 Mb, but that is still a bit costly.</p>
  
  <p>The surefile XML files for these are huge too. Since they tend to contain very repetitive data, I could save a lot of disk space by zipping them. But I know no Jenkins plugin for this.</p>
  
  <p>Note: I am already deleting old builds not needed anymore.</p>
