title: org.eclipse.ui can't be resolved?
body: <p>Could you please tell me how to resolve that package import, I thought it is an element of SWT and I've already have SWT installed into Eclipse IDE. Why is it so bothersome? I guess I have to download some *.jar or *.zip files to add to my project as external library.</p>
  
  <p>Please give me a solution. Thank you!</p>
