Go to implementation for dependency sources

[Z1kkurat]

Describe the bug
VSCode + Metals fails to find trait implementations in dependency's source files, for Doobie in particular (when using in project that depends on doobie as a dependency).

To Reproduce
Steps to reproduce the behavior:

1. Any project which has doobie dependency will do
2. Go to sources, in particular doobie.free.preparedstatement
3. Right-click on trait Visitor inside object PreparedStatementOp, choose Go to implementations
4. See No implementation found for Visitor

Expected behavior
Implementations are shown in pop-up window. If you try to do this while in doobie's source repository, it works fine. Clean compiles don't help either.

Screenshots

Installation:

• Operating system: Windows and Linux
• Editor: Visual Studio Code
• Metals version: v0.9.0

Thanks for reporting! That is currently expected, since we don't index the inheritance graph inside the dependencies. It would be a good improvement for sure, but it might be quite hard to achieve efficiently.

@tgodzik Are there any plans to support this? This would be a really game-killer feature IMHO. I think many users currently have to switch to IDEA to get that functionality.

There are certainly plans, but we've not been able to work on it just yet. It also depends on scalameta/metals#1287 which should allow us to effectively query the classpath.

This is now working for both Scala and Java
