Metals: semanticdb-scalac is silently disabled for Scala 2.12.8
Describe the bug
I found some error messages in vscode's console
bad option: -P:semanticdb:synthetics:on
bad option: -P:semanticdb:failures:warning
To Reproduce
Steps to reproduce the behavior:
ThisBuild / scalaVersion := "2.12.8"sbt metalsEnable bloopInstall- See error
Expected behavior
No error message
Installation:
- Operating system: macOS
- Editor: Visual Studio Code
- Metals version: v0.5.0-M1
Additional context
I have to manually add the following settings in my build.sbt in case of those errors
addCompilerPlugin("org.scalameta" % "semanticdb-scalac" % "4.1.5" cross CrossVersion.full)

Thanks for reporting! I am unable to reproduce, I created a minimal sbt build, ran "import build" and compilation works as expected. Can you try reproducing in https://github.com/olafurpg/vanilla ?

The error message goes away when I clone a clean repository and run "Import Build".

It is turned out that an sbt setting ThisBuild / scalaVersion := "2.12.8" who cause this error.
I usually create a local.sbt that contains Scala versions, which is ignored by .gitignore. Therefore, this error never occurs in a clean clone.

I added the local.sbt file and now it is reproducible.
Run the following command and click Import Build
git clone https://github.com/Atry/Binding.scala.git --branch=metals-error && cd Binding.scala && code .
Also note that the error message can be avoided by setting ThisBuild / scalaVersion := "2.12.7" instead of 2.12.8

@Atry I've tried the command verbatim and the build import succeeded on my computer.
Can you share which global sbt plugins you have on your machine?

If I run METALS_ENABLED=true sbt metalsEnable bloopInstall in a shell instead of clicking the "Import Build" button, then everything goes well after I restart vscode.

Thanks for the information and investigating further. What happens if you point the sbt launcher configuration to your sbt script? See https://scalameta.org/metals/docs/editors/vscode.html#custom-sbt-launcher By default, Metals uses java -jar sbt-launch.jar where sbt-launch.jar is embedded our resource directory.

Step 1
git clone https://github.com/Atry/Binding.scala.git --branch=metals-error && cd Binding.scala && code .
Step 2
Set vscode's sbt script to /usr/local/bin/sbt
Step 3
Click "Import Build"

It seems that some randomly selected projects are broken. You distinguish broken projects and good projects from their bloop configuration:

@Atry Thanks for the detailed reproduction! It's surprising to see the semanticdb-scalac plugin not getting enabled via libraryDependencies += compilerPlugin(semanticdbScalac) when it looks like the scalacOptions += List("-P:semanticdb:synthetics:on") settings are getting picked up. We enable these settings together
This needs more investigation. In the meantime, I think a workaround is to
- select the "Don't show again" option when asked to import the build
- add
addCompilerPlugin("org.scalameta" % "semanticdb-scalac" % "4.1.5" cross CrossVersion.full)to build.sbt - run
METALS_ENABLED=true sbt bloopInstall(withoutmetalsEnable)

I overridden bloopInstall for debugging (https://github.com/Atry/Binding.scala/blob/metals-error/Binding/.jvm/local.sbt)
In vscode, when I click "Import Build", I can see some logs below
[info] List(org.scala-lang:scala-library:2.12.8, com.thoughtworks.extractor:extractor:2.1.0, com.thoughtworks.enableIf:enableif:1.1.4, com.thoughtworks.sde:core:3.1.1, org.scalatest:scalatest:3.0.7:test, org.scala-lang:scala-reflect:2.12.8, org.typelevel:macro-compat:1.1.1, org.scala-lang:scala-compiler:2.12.8:provided, org.scalamacros:paradise:2.1.0:plugin->default(compile), org.scalameta:semanticdb-scalac_2.12.8:4.1.4:plugin->default(compile))

The log indicates that the libraryDependencies settings are added as expected. Unfortunately scalacOptions does not contain the corresponding -Xplugin:... flags.
If I run METALS_ENABLED=true sbt metalsEnable bloopInstall from command line, the log is different:
[info] List(org.scala-lang:scala-library:2.12.8, com.thoughtworks.extractor:extractor:2.1.0, com.thoughtworks.enableIf:enableif:1.1.4, com.thoughtworks.sde:core:3.1.1, org.scalatest:scalatest:3.0.7:test, org.scala-lang:scala-reflect:2.12.8, org.typelevel:macro-compat:1.1.1, org.scala-lang:scala-compiler:2.12.8:provided, org.scalamacros:paradise:2.1.0:plugin->default(compile), org.scalameta:semanticdb-scalac_2.12.8:4.1.5:plugin->default(compile))

A -Xplugin:... flag is created for the semanticdb-scalac when bloopInstall is executed in my shell.
Also the versions of semanticdb-scalac are different in command line (4.1.5) and in vscode (4.1.4). It looks like that my vscode runs an old version of sbt-metals

I just ran the steps in https://github.com/scalameta/metals/issues/647#issuecomment-482596843 including customizing the sbt script to /usr/local/bin/sbt and I am unable to reproduce.
Does your sbt script contain customizations? I installed sbt with homebrew.

Could it be that you have sbt-lock installed? From Gitter https://gitter.im/scalameta/metals?at=5cb20e05c55bd14d35dbcb07
David van Geest @DWvanGeest Apr 13 18:27
@olafurpg good hints in that referenced issue. In my case it appears that sbt-lock is interfering somehow. Once I remove the plugin and the generated lock.sbt, things work as expected. I will try and file a more detailed bug.
olafurpg

I don't know sbt-lock and I think I don't use Ruby.

How is your /usr/local/bin/sbt script?

It turns out that I have a corrupted JAR at ~/.coursier/cache/v1/https/repo1.maven.org/maven2/org/scalameta/semanticdb-scalac_2.12.8/4.1.4/semanticdb-scalac_2.12.8-4.1.4.jar. When sbt generates scalacOptions for compiler plugins, the scalac-plugin.xml resource is not found in the JAR. As a result, semanticdb-scalac_2.12.8-4.1.4.jar is not recognized as a compiler plugin to sbt, and the -Xplugin is omitted.
When I debug this problem some days ago, I tried to add export SCALAMETA_VERSION=4.1.5 to my ~/.bash_profile and forget to restart vscode. Therefore, metals in vscode still use the corrupted semanticdb-scalac_2.12.8-4.1.4.jar while sbt started from command line can see the new environment variable and installed a good semanticdb-scalac_2.12.8-4.1.5.jar.
Now I deleted my cached semanticdb-scalac_2.12.8-4.1.4.jar and sbt redownloaded it. Everything goes well now.

It seems that coursier did not check file integrity if you kill JVM when downloading a file.

Thank you for tracking down the issue!

@Atry it could be that this issue is fixed if you upgrade to the latest coursier, it sounds similar to https://github.com/coursier/coursier/issues/988 according to @alexarchambault
