Problem starting with Wurst

[HerlySQR]

I tried to start to use wurst following the steps, but the VSCode throws me an error:

Loading Wurst version 1.8.1.0-jenkins-Wurst-1271
Workspace null. Make sure to open a valid project root using File->Open Folder, before opening code files.
[Error - 23:27:12] Server initialization failed.
TypeError: Cannot read property 'capabilities' of null
    at c:\Users\SEBAS\.vscode\extensions\peterzeller.wurst-0.5.10\node_modules\vscode-languageclient\lib\client.js:1972:34

And every time I wanna run the example map it also throws me an error, what did i do wrong?

 

[HerlySQR]

Anyone knows?

 

[Daffa]

@Bannar @Frotty might have some ideas on how to resolve this issue.

 

[HerlySQR]

@Bannar @Frotty I invoke you.

 

[Frotty]

It tells you the error... Read. And follow instructions from the guide correctly.

Oh I miss the word "Folder" I think it says "File" thank you, now I have another problem, when I wanna try run a wurst map with VSCode this happens:

And for some reason opens the Reign of Chaos and not the Frozen Throne.

 

[Frotty]

Wurst reads the wc3 location from registry. if that is not the one you want to run, you need to specify another installation in settings.
war3.exe means this isn't reforged and thus new natives will not work.

 

[Bannar]

I've been invoked!

@HerlySQR @Daffa why hello there
@Frotty long time

If issue persists after all help from Frotty, it is advised to provide reproduction steps - step by step what you do to encounter the issue.

 

[HerlySQR]

At the end, how can I solve the problem?, these are the settings:

{
  "wurst.javaOpts" : [ "-XX:+UseG1GC", "-XX:+UseStringDeduplication", "-XX:+AggressiveOpts", "-Xmx1G" ],
  "files.associations" : {
    "wurst.build" : "yaml"
  },
  "search.useIgnoreFiles" : false,
  "yaml.schemas" : {
    "./.vscode/wbschema.json" : "/wurst.build"
  },
  "wurst.wurstJar" : "C:\\Users\\SEBAS\\.wurst\\wurstscript.jar",
  "wurst.wc3path" : "C:\\Users\\SEBAS\\Documents\\WarCraft III"
}

Edit: Wait, I are you trying to tell me that to use wurst I have to use Reforged?

No, but reforged is default since we target the latest official patch. The standard library makes use of the new natives.
If you want to target older patches, you need to provide the old common.j and blizzard.j and use old standard library/no new features.

 

[HerlySQR]

Ok, where I get the old standard library?

 

[HerlySQR]

Well, after searching I found you already solved it in another tread

[Wurst] - HelloWorld - "Cannot load map data"

So I was following the instructions at WurstScript • Wurst Beginner Guide and got a new WurstScript project set up in VS Code. But when I F1 > Run a wurst map, wc3 (1.28.5) runs and displays the dreaded "Cannot load map data" error... The map opens just fine in World Editor (Extended), but the...

so now the problem is solved.

 

[HerlySQR]

Now suddenly this message apears when I wanna run the map, how?

 

[HerlySQR]

I wanna know why because the only change I did is installing Java extensions to VSCode and disabling those didn't work.

 

[Frotty]

Stuff doesn't just suddenly not work - something changed.
In any case, if you have any issue, provide log from "Output Tab" -> "wurstLanguageServer".
It will tell the specific problem.

This is what's says:

What is the problem with "Java Virtual Machine"?, is this because I added Java extensions to VSCode? or maybe because I installed another program to Java called "Apache NetBeans".

 

[Frotty]

I think the error is pretty obvious "Unrecognized VM option 'AggressiveOpts'".
This means you are not using Java 8.
A simple google search would've yielded that result.

 

[HerlySQR]

Sorry but what is obvious for you is not obvious for everyone (I'm not very into "advanced programming").
Anyway, I searched and I found that the option 'AggressiveOpts' is a function that becomes obsolete in JDK 11 and was removed in JDK 12, so the problem came from that I installed JDK 16 so I uninstalled it and reinstalled Java 8, and now the problem is solved again, thank you.

I'm not saying that the underlying cause is obvious, but the error itself, since it says "Error" in front.
Googling an error should be your first cause of action, before posting, imho.
You can also stay with Java 16, but then you need to remove the JVM option from settings.json

 

[HerlySQR]

@Frotty this is the settings, what should I do?, I don't wanna mess it.

{
  "wurst.javaOpts" : [ "-XX:+UseG1GC", "-XX:+UseStringDeduplication", "-XX:+AggressiveOpts", "-Xmx1G" ],
  "files.associations" : {
    "wurst.build" : "yaml"
  },
  "search.useIgnoreFiles" : false,
  "yaml.schemas" : {
    "./.vscode/wbschema.json" : "/wurst.build"
  },
  "wurst.wurstJar" : "C:\\Users\\SEBAS\\.wurst\\wurstscript.jar",
  "wurst.wc3path" : "C:\\Users\\SEBAS\\Downloads\\Warcraft III 1.27"
}

 

[Frotty]

Unrecognized VM option 'AggressiveOpts' -> remove the entry "-XX:+AggressiveOpts", in the 2nd line.

I supposed it, just I fear I get an error like "Missed argument" or "It was an important argument", thanks.

 

[HerlySQR]

Now, finally, where can I ask things about Wurst?

 

[Frotty]

You can ask here, but unless I am mentioned I won't be aware of it.
You can also join the matrix chat Element

Thank you.

I know you shared a link to a chat in the tutorials, but it wasn't this.
