Rename Symbol offset error preventing F2 to work in vscode

[bjornregnell]

Describe the bug

1. Double click on a method name
2. Press F2
3. First letter of method name is missing and one paren is included

The "Rename Symbol" feature does not work then... (But F12 "Goto definition" still works)

Here is a dump of Metals Doctor:

Here is the build.sbt:
https://github.com/reqT/reqT/blob/4.x/build.sbt

Expected behavior

The method name should be properly marked in the rename popup.

Operating system

Thanks for reporting! I can't seem to reproduce, it might have been flaky, but in those cases we usually don't rename. Are you able to still reproduce?

I did a quit+import build as I am also getting a red-colored file in the explorer pane even if there are no compile errors in sbt. Now I can't reproduce, unfortunately. But I still have red coloring of the file even if there is no compile errors in sbt but it seems to complain about the colon after object so maybe it start thinking that I'm on Scala 2 or something???

(I usually try now to delete all dot-files and target, but I'll wait a bit if you want me to check something else... @tgodzik )

AHA! When I added a space on the line with the error-marked colon and saved then the error went away (sic!) and looks like:

F2 continue working so can't reproduce I'm afraid...

[tgodzik]

We can try to add a new check just in case unless we already do it.

Seems like an off-by-one bug somewhere... :)
