title: Missing artifacts from maven .m2 repository
body: <p>I'm trying to add dependencies to my project through pom file. But while building workspace it's showing error as missing more than 400 artifacts. Seems like maven is not downloading related jars to my .m2 folder.</p>
  
  <p>I tried cleaning and updating projects several times but errors are still there.</p>
  
  <p>Any help would be appreciated.</p>
