Unable to run existing java Play Framework project on windows machine

Question

I'm getting

Error: Unable to access jarfile C:\Users\stepa\workspace\sse-chat-java\\activator-launch-1.1.0.jar

when running Markus Jura's Play Framework simple chat application on windows 10 system.

On a Ubuntu machine Markus Jura's Play Framework simple chat application works without any problems.

This is what I tried so far:

• reinstalling Typesafe Activator to the currently newest version (2.4.3 - same as on Ubuntu machine)
• searching for activator-launch-1.1.0.jar (not present on any of the machines)
• searching for someone with same problem

I'm running out of ideas. I appreciate any suggestions.

Answer 1

There are 2 places where you may try to change version. See image below (but please also check another file).

I'm not sure it will fully fix your issue, but it worth a try.
