title: How to clear .m2 Maven folder?
body: <p>My computer runs Windows 10 and I work with Java and Eclipse. Recently Windows warned me that I'm running into short disk space and after some study I noticed that I have a folder named <code>.m2</code> under my user's folder (<code>C:\Users\MySelf</code>) that occupies 202Gb.</p>
  
  <p>I know this folder belongs to Maven. Since this folder is bigger than all my projects and their dependencies together, it seems to me that Maven is keeping unnecessary files, so I want to get rid of them.</p>
  
  <p>Is is safe simply delete the folder contents or should I run some particular process in order to save space and keep Maven working well?</p>
