sdk use does not have any effect

[rahulsom]

This is what I see.

 ~/src  sdk ls java                                                                                                                                                                                                  Fri Jul 13 22:12:14 2018

Since this project ist mostly about completion, I checked that. Seems to work as expected on my end:

As for sdk use not doing what it's supposed to do: can confirm. Works with bash, so it's about the fish wrapper.

Fish calls bash to perform sdk actions; I assume bash changed the version in the current (bash) shell, which then exited. This is a conceptual issue, not a programming bug. Will have to think and tinker; any input appreciated.

FWIW, sdk default works just fine.

sdk directly manipulates PATH. Therefore, the solution is to copy PATH from the bash subshell to the current shell.

Thanks for your report!

Nota bene: fish-sdk now copies PATH always (as long as sdk succeeds). I'm sure issues can be caused by that. I might also have missed some escaping or another so some PATH entries might break the script. Awaiting reports.
