Eclipse plugin error: Cannot run powershell.exe

[vpinna80]

When starting up Eclipse, I see the following in the log, and the plugin seems not to work.
It happened just after Eclipse reboot post-installation.
I think it may be related to scalameta/metals#2934 but I can't really say for sure.

I'm on a Windows 10 machine with 16GB ram and using Eclipse 2021-06 on OpenJDK 11.

Thanks for reporting!

I just found out that there is metals-eclipse plugin. I'll transfer this issue to this repo.

I don't think that it's related to scalameta/metals#2934. It seems that coursier version in metals-eclipse is too outdated so probably that the reason.

The project is not actively maintained at the moment, though I think it would be awesome for someone to pick it up as I don't imagine it would require a lot of work.
