body: <p>While importing exisiting gradle project in eclipse , I am getting an error message which says</p>
  
  <blockquote>
    <p>"IllegalArgumentException:Host name may not contain blanks".</p>
  </blockquote>
  
  <p>I verified my <code>gradle-wrapper.properties</code> and found that proxyHost, port, username and password are correct.What might be causing this error in this case?</p>
  
  <p>I am using springboot, gradlewrapper and gradle-4.8.1.zip already exists in the project.</p>
