Arch Linux User Repository

After installing this and invoking kotlin-language-server, I got this:

/sbin/kotlin-language-server: line 87: cd: /sbin/../share/kotlin/kotlin-language-server/bin/..: No such file or directory

The kotlin-language-server executable is installed to /usr/bin. On Arch Linux, /sbin is a symlink to /usr/bin and is placed as the first one in PATH, so running the command by name finds it in /sbin. Invoking the language server directly by running /usr/bin/kotlin-language-server works.

The aforementioned problem happens because, /usr/bin/kotlin-language-server is a symlink that links to the actual executable's path that's relative to it. The same relative path, when resolved relative to /usr/bin/kotlin-language-server and /sbin/kotlin-language-server, results in different things, thus the problem happens. I've tried editing PKGBUILD, making the link's path not relative (by removing the r flag in the usage of ln in package()), and it worked. Not sure if there's any reason why we might want the link to be relative.

The upstream URL could be updated to https://github.com/fwcd/kotlin-language-server (same goes for the kotlin-language-server-git package).

The package doesn't install if you have the latest version of jdk (19) installed. Java 19 is not yet supported by upstream. I suggest changing build() so that, if jdk19 is installed, JAVA_HOME is set to an earlier version.

Thank you for the feedback, everyone!

Little amendment: need to change it to -name "*-1*jdk" to not catch openjfx ;)

btw I'd be open to co-maintain

I agree, the default jvm version should first be checked from java -version 2>&1 | grep version | cut -d'"' -f2

This will not work if you install a newer version of JDK, but use the old one as default, I guess we'd better change the code to find JVM to

    jdk="/usr/lib/jvm/default" &&
      test -n "$jdk" && export JAVA_HOME="$jdk"
