Solve the Popup window in nvim when no scalafmt is set

When you create a scala project and are using nvim 0.10 and metals together, there is a possibility that you face the following (Github issue)[https://github.com/scalameta/nvim-metals/issues/623]

It seems nvim opens a modal window, but the interaction is disabled.

So the only way to fix is by typing the following command in the nvim terminal:

:lua vim.lsp.buf.format()

This will let you interact with the modal and you'll be able to choose to create a .scalafmt.conf for you.

Or you could also manually create a file like this (assumming you know the version of your scalafmt that comes with metals:

version="3.7.15"
runner.dialect= scala213

Logs nvim-metals

Sometimes metals can't fail by quiting on vim. The best place to look for the issue is at the logs:

:MetalsToogleLogs

Bloop and dependencies from a Containerized app

Sometimes you might have a project in scala 2.13 with java 8 and your nvim-metals is set with scala 3.3 with jvm 17.

You could choose from:

• Share the docker .bloop folder with your local host

• Run sbt compile to create a .bloop folder and use the scala/java versions needed in docker, then switch to nvim-metals scala/java version
