title: Does the Eclipse 2019-3 installer require Internet?
body: <p>We have need to install Eclipse on a network-isolated (on purpose) Windows machine. We can transfer files by USB, so we can physically put the Eclipse installer executable on the machine. </p>
  
  <p>There is already a JDK (1.8) on the machine. </p>
  
  <p>Question is, will just the installer be sufficient? Does it try to "reach out" for additional web resources? </p>
