You can also try http: // localhost: 8080 / studio / api / 1 / services / getInfo.json , which will give you something like this:
{"version":"3.0.0-SNAPSHOT","id":"33ed8125aa029a8170ed11d9cee62b802f45cd38","uiId":"f5318d804d51eea2501fdf1bc832af4c2ba5e30a","buildDate":"2017-05-09T10:38:21-06:00"}
Note that this also works for 2.5.x (starting from 2.5.6)
