Classpath variables can be used in a Java Build Path to avoid a reference to the local file system. Using a variable entry, the classpath only contains a variable and the
      build path can be shared in a team.
      The value of such variables is configured on the
      
      Java > Build Path > Classpath Variables preference page.

| Edit... | Allows you to edit the selected variable entry. In the resulting dialog, edit the name and/or path for the variable. You can click the File or Folder buttons to browse for a path. |

Certain class path variables are set internally and can not be changed in the Classpath variables preferences:
These variables are deprecated and should not be used anymore. Instead use a JRE System Library.
