title: Why is my manifest file 'no longer in the Jar'?
body: <p>I'm trying to compile a runnable jar file, and to do so, I wrote a manifest file. When eclipse is finished compiling, one of the warnings is
  'Project/src/META-INF/MANIFEST.MF was replaced by the generated MANIFEST.MF and is no longer in the jar.' Why does this happen, and how do I stop it?</p>
  
  <p>Thanks in advance. </p>
