java.lang.OutOfMemoryError: Java heap space #120

Description

I'm not sure how to repro. I'm trying to use this extension in a big private repository. When I start vscode, the cpu (mac intel) goes brrrr, after a while, the kotlin output shows the error detailed bellow. The go to definition does command does not work (cmd+click triggers an infinite blue loading animation at the top of the editor, but nothing else happens).

Extension version

VSCode 1.76.2 fwcd.kotlin v0.2.26

Additional context

Is there any way to assign more heap space to the java runtime?

@fwcd this is language server issue, not a vscode plugin issue, could we transfer it? Possibly also a duplicate of https://github.com/fwcd/kotlin-language-server/issues/441 .

You can change the java heap space with environment variables. The most common way is to use the java option -Xmx8g (which would make it 8GB). This can be done by setting JAVA_OPTS or similar environment variables variables. See our discussion in the language server repo for more details: https://github.com/fwcd/kotlin-language-server/issues/441

Some things to think about:
