I'm having exactly the same issue. From CLI everything performs well. I've tried reinstalling both bloop and metals, disabling extensions, cleaning both .metals and .bloop.

One thing that I noticed is that since I have this issue, each time I open vscode from cli the message "Downloading Metals 0.8.0" is shown for a fraction of a second, while before it wasn't happening.

Thanks for reporting! Does the Output tab contain anything meaningful?

Nope. Debug Console is empty and `Output -> Metals' dosen't log anything. Other functionalities works correctly.

Is it all projects? Also when trying to run? It does work on anything that I am trying it on, so it would be good to find a proper reproduction.

There might be some more info in .metals/metals.log

Yeah, it's happening in every project and only on the single machine. Here is metals.log

@LukaszByczynski I don't have any issues when running the examples. Could it be an issue of conflicting code lenses? I see there is an additional extension installed. If you disable it, does it help? The one that provides the additional lenses on the right?

tgodzik picture tgodzik on 14 Jan 2020

This lens comes from GitLens. I did another test. I removed all prefs, settings, and extension, then installed only metals and the issue still exists. When I clicking on the run lens I saw for a second in the status bar: "compling examples" but nothing happens.

My JDK:
openjdk version "1.8.0_232" OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_232-b09) OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.232-b09, mixed mode)

I wonder, maybe there is a setting for enable more verbose logs from metals and bloop

I'm experiencing the same issue when clicking "debug", while "run" works

I had not luck figuring out what's going on and I am out of ideas. It might be useful to enable tracing:

touch /Users/lukaszbyczynski/Library/Caches/org.scalameta.metals/bsp.trace.json

it will log all requests going back and forth the build server. We might get some more info there to see if Metals is even contacting the build server.

Thanks! It looks like bloop starts the debug session without any issues, although I don't see a log that the actual debuggee (the ex01_simple class) has even started so that may be one thing to investigate further.

Could you also enable tracing of lsp communication (to make sure lsp receives the debug adapter uri)
touch /Users/lukaszbyczynski/Library/Caches/org.scalameta.metals/lsp.trace.json
as well as debug protocol communication (to see where it get's stuck if it starts)
touch /Users/lukaszbyczynski/Library/Caches/org.scalameta.metals/dap-server.trace.json
touch /Users/lukaszbyczynski/Library/Caches/org.scalameta.metals/dap-client.trace.json

Visual Code - metals extension has version 1.7.2

LukaszByczynski picture LukaszByczynski on 21 Jan 2020

Thanks! It looks like the response to the debug-adapter-start command is not being sent to the vscode for some reason.

Since this happen only on this one machine, let's consider the most embarrassing scenario of a deadlock inside of metals: how many cores does this machine have? Could you make a thread dump of metals some time after clicking on a code lens and observing the "time: compiled examples in (...)"? That would greatly help us narrow down the potential cause.

We usually get later:

[Trace - 00:56:41 PM] Received notification 'build/logMessage'
Params: {
  "type": 3,
  "message": "Listening for transport dt_socket at address: 38651"
}

I don't see it here. @marek1840 Could it be an issue in Bloop itself?

tgodzik picture tgodzik on 23 Jan 2020

Another thing that might be happening is that Bloop run is not starting. We might try to check it by installing Bloop manually (https://scalacenter.github.io/bloop/setup) and then try to run from commandline: https://scalacenter.github.io/bloop/docs/cli-reference#bloop-run

However, I understand if that is too much hassle right now.

tgodzik picture tgodzik on 23 Jan 2020

I installed bloop from the link above and the issue still exists. When I run example from command line everything works:

I'm having exactly the same issue. From CLI everything performs well. I've tried reinstalling both bloop and metals, disabling extensions, cleaning both .metals and .bloop.

One thing that I noticed is that since I have this issue, each time I open vscode from cli the message "Downloading Metals 0.8.0" is shown for a fraction of a second, while before it wasn't happening.

I have good news - I resolved the issue. I think the problem is related to security settings introduced in the latest OSX releases. So, I did access to full disc in security settings in user preferences and after VSCode restarts run/debug feature works like a charm.

LukaszByczynski picture LukaszByczynski on 11 Mar 2020

@LukaszByczynski Cool! I don't know much about OSX unfortunately, but glad that helped!

@TonioGela Would this also help you? Are you on OSX?

tgodzik picture tgodzik on 12 Mar 2020

For what it's worth -- this is happening to me now. I tried giving VSCode full disk access and it didn't solve it.

The interesting thing though is everything was working perfectly on this machine, then I upgraded the version of adoptopenjdk8 to the latest and it stopped working. I'm now on 

openjdk version "1.8.0_242"
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_242-b08)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.242-b08, mixed mode)

previously I was on something like 1.8.0_232

Update:
Just tried downgrading -- and still experiencing the issue. So this may be unrelated -- not really sure.

One more tip. Check if you have openjdk installed in your brew dependencies (brew list). I removed it recently and this fact is maybe corelated.

LukaszByczynski picture LukaszByczynski on 13 Mar 2020

@LukaszByczynski interesting. I do have it installed -- and it looks like openjdk in brew is currently 13. Will do some experimentation.

tylerprete picture tylerprete on 13 Mar 2020

@tylerprete I had some issues recently and it turned about it was weird openjdk installation, which didn't show up as JDK:

Using Scala v2.12.8 and Zinc v1.3.0-M4+32-b1accb96
Running on Java JRE v1.8.0_242 (/usr/lib/jvm/java-8-openjdk-amd64/jre)
  -> Doesn't support debugging user code, runtime doesn't implement Java Debug Interface (JDI).
Maintained by the Scala Center (Jorge Vicente Cantero, Martin Duhem)

We run and debug via Bloop, so you can check if Bloop supports it using your JDK. You can use coursier to do it:

coursier launch ch.epfl.scala:bloopgun-core_2.12:1.4.0-RC1-142-90456e06 -- about
tgodzik picture tgodzik on 26 Mar 2020

@tylerprete Did you manage to get anywhere with your experimentation?

tgodzik picture tgodzik on 9 Apr 2020

@tgodzik I still don't know -- I've had it work on & off on different machines. Haven't figured out the root cause.

tylerprete picture tylerprete on 10 Apr 2020

Closing this for now, since we don't have any clear reproduction and the main issue was fixed. We can open a new issue if any new problems arise.
