title: Launch configuration FastDateFormat references non-existing project jersey
body: <p>I'm new to Spring development and so I tried adding the Jersey RESTful api dependency to one of my maven projects. Unfortunately I had to add some remote repository and it seemed to have messed up my launch configurations. Now when I try to launch any old Maven project, I'm always getting this error:</p>
  
  <p>Launch configuration FastDateFormat references non-existing project jersey.</p>
  
  <p>I'm not sure how to fix this in eclipse. Also I am using Spring Tool Suite if that makes in difference. Help! </p>
  
  <p>Thanks</p>
