Thanks for reporting. This looks like the classpath is not populated fully or there are things missing from the jar.

How did you setup the server? I am not very well versed with emacs, but it might be good to ask around https://github.com/emacs-lsp/lsp-metals/

Crandel commented 4 years ago

I setup metals server from AUR using yay Before 0.9.2 it works perfectly Here you could view changes in PKGBUILD made by maintainer of package

tgodzik commented 4 years ago

Maybe the package is broken? It looks like it is missing the implementations of several methods, that should be there by default. What Scala version are you using?

I tried to reinstall it, but nothing changed

Not sure I understand, we are using the build definition to configure the Scala version. What Scala version do you have in your *.sbt, *.gradle, *.sc or pom.xml file?

Crandel commented 4 years ago

I try to remove and install it again this is an output of yay

The JDK which will be used to run metals will be the newest one which
is supported by metals and installed on your system.

If you would like to use a different JDK set the METALS_JDK_PATH to
the /bin directory for the JDK install.

For example, if you wanted to use JDK 13 (not currently supported by
metals) then you would set
METALS_JDK_PATH="/usr/lib/jvm/java-13-openjdk/bin" in the environment.

As of 0.9.0-4 the default jvm options used to run metals have
changed. They are now "-XX:MaxHeapFreeRatio=20 -XX:MinHeapFreeRatio=5"
and if you are using JDK >= 10 also '-XX:MaxRAMPercentage=25'. This is
expected to give better memory usage characteristics to a typical
usage of metals.

You may override these settings by settings METALS_JAVA_OPTS in the
environment, e.g. your .bashrc/.zshrc. For example, if you wanted to
use the pre 0.9.0-4 options you could add this to your shell init
file.

export METALS_JAVA_OPTS='-XX:+UseG1GC -XX:+UseStringDeduplication -Xss4m -Xms100m'

I didn`t change METALS_JAVA_OPTS

Not sure I understand, we are using the build definition to configure the Scala version. What Scala version do you have in your .sbt, .gradle, *.sc or pom.xml file?

In my build.sbt scalaVersion := "2.12.11"

Ok, if the listed files are the only ones included then it looks like the package is not building correctly. It's missing all the files from mtags package and that's why it's not starting - it's really missing those files. I suggest that you contact the maintainer of the package or try using the alternative ways to install emacs.

@tgodzik Thank you for your help, I will create an issue for AUR then
