running sbt as a subprocess causes confusion

[scalway]

I've installed sbt 1.6.1 in a system:

sbt --version
1.6.1

when I've tried to start vite dev server on
scalajs-sbt-vite-laminar-chartjs-example on branch laminar-end-state

$ npm run dev

> livechart@0.0.0 dev
> vite

[info] welcome to sbt 1.8.2 (Ubuntu Java 11.0.18)
[info] loading settings for project global-plugins from common.sbt ...
[info] loading global plugins from /home/slovic/.sbt/1.0/plugins
[info] loading settings for project scalajs-sbt-vite-laminar-chartjs-example-build-build-build from metals.sbt ...

so it starts latest sbt version (as file build.properties defined) but sbt-runner version was still 1.6.1 so command failed as seen below:

...

I was able to fix it by simply install current sbt version:

$ cs install sbt

I really don't know what to do with that, it is not critical (simple OS config fix) but could be blocker for many if cannot find help :(.

Hum, so that's because you had previously installed an older version somewhere on your system, which took precedence?

We probably cannot really do anything about it. Perhaps the existence of this issue with the searchable error message will help future users to troubleshoot, if they end up in the same situation?

What we could do is probe sbt --version and fail if it is too old (hopefully there is a "setup" hook for the plugin or something).
