Position.start on NoPosition when importing scalaz-zio #520

Closed iravid closed 5 years ago

iravid commented 5 years ago

Describe the bug Hi! I'm getting a bunch of these errors when importing the scalaz-zio project in emacs with lsp-scala and metals 0.4.3:

failed to generate semanticdb for /Users/iravid/Development/personal/scalaz-zio/interop-future/shared/src/main/scala/scalaz/zio/interop/future.scala:

To Reproduce Steps to reproduce the behavior - import scalaz-zio in Emacs.

Installation:

Thanks for reporting! This looks like a regression in the latest SemanticDB release, it's easy to mess up with compiler APIs. Pending fix in https://github.com/scalameta/scalameta/pull/1828

olafurpg commented 5 years ago

Workaround is to use v0.4.0 until a new SemanticDB release is out.

iravid commented 5 years ago

Sounds good, thanks @olafurpg!

olafurpg commented 5 years ago

I just kickstarted a v0.4.4 release https://travis-ci.org/scalameta/metals/jobs/487916036

0.4.4 is out and the vscode extension has updated
