Activating extension `fwcd.kotlin` failed

[Goddchen]

Hi!

I'm having issues opening a folder which contains multiple projects in subdirectories. They contain Maven projects and are made up of a mixture of Java and Kotlin files. The Java language server works fine, but the Kotlin one doesn't start (it works fine when I open single projects).

The exception thrown is:

[Extension Host] Here is the error stack:  Error: Internal error.
	at handleResponse (/Users/martinliersch/.vscode/extensions/fwcd.kotlin-0.1.12/node_modules/vscode-jsonrpc/lib/main.js:436:48)

	at tryOnImmediate (timers.js:751:5)
	at processImmediate [as _immediateCallback] (timers.js:722:5)

Any ideas?

So when I dug into the stack trace, it turned out the space in the directory was causing the issue for me:

Illegal character in path at index 40: file:///Users/user/Documents/Some App/tut-spring-boot-kotlin

So as a work around I just got rid of the space in "Some App" and it worked.

@samdoctor That is a known issue, tracked here: https://github.com/fwcd/kotlin-language-server/issues/200

[stephaneeybert]

@samdoctor How did you do to dig into the stack trace ?

@stephaneeybert I have the same problem these days, but i resolved it by setting the mvn PATH just now

[susonthapa]

I am having this problem with version 0.2.26. Here are the logs.

I have the same Error: write after end variant too

[izaban]

For me, installing the mvn maven command fixed the Error: write after end, even if I'm not using maven in my project.

[susonthapa]

@izaban I tried installing mvn with Homebrew but I am still getting the same error. By the way, I am running a ReactNative project so don't know if this is specific to ReactNative.

[timolehto]

Hey thanks @susonthapa, it seems to work. At least partially. I still get some errors loading the workspace: but e.g. navigating to definition seems to now work, so I guess it sort of works. It doesn't seem to support running specs anyways so I guess this is pretty much all it supports. 👍
