title: Change java build path for multiple projects in Eclipse
body: <p>In Eclipse, I have a libs project. This project has a test.jar file.</p>
  
  <p>I have 15 other projects in eclipse that use test.jar under Java Build Path/Libraries.</p>
  
  <p>New versions of test.jar are made every month, and the name will change (test1.jar, test2.jar)</p>
  
  <p>Once a new version is available, I remove the old one from the libs project and add the new one. My question is, how can I modify the 15 projects that use this jar file to reference the new one? I know how to do it one project at a time by configuring the build path for each project. Is there a way to make a mass change to all 15 projects at the same time?</p>
