Determining GWT Version from jar sizes

I ran into a few cases trying to build a GWT project that does not clearly state which GWT version it uses. AFAICT the gwt-servlet.jar doesn’t give any clues in the manifest or else where.

Here’s a list of versions of gwt-servlet.jar and file sizes (KB):

  • 2.0.0 – 1,524 KB
  • 2.0.1 – 1,535 KB
  • 2.0.2 – 1,538 KB* see below – 1,574,024 Kb,
  • 2.0.3 – 1,558 KB* see above – 1,574,034 Kb
  • 2.0.4 – 1,538 KB
  • 2.1.0 – 2,776 KB
  • 2.1.1 – 2,906 KB
  • 2.2.0 – 4,280 KB
  • 2.3.0 – 4,889 KB

Prior to 2.0.0 there is a separate version for Win/Mac/Linux

Got any others to add?
