title: How to add external jars in eclipse oxygen, so that they are automatically available to all other projects?
body: <p>I am learning spring framework.I am practicing in Eclipse Oxygen.</p>
  
  <p>The website has given me 20 - 25 demo projects to practice and they asked me to import the required external jar files to each projects. The thing is that I have to add the external jar files to each project manually.( ie. I have to select the project => right click => Build Path => Add external jar files => select the jar files => Apply. Now I have to repeat these steps for each project).</p>
  
  <p>I wanted to ask is there any way, that I can add these external jar jar files once in eclipse and they will be available to all of my demo projects ?</p>
  
  <p>I am new to eclipse, I don't know whether there is some method for this or not, if there is it will greatly reduce my manual efforts.</p>
