Simply don't use VSC for Java, there are far better Options:

• IntelliJ
• Eclipse

[vague oyster]

but this is what im used to and what i prefer
its never had this issue in the past, and im not looking to change IDEs

Maybe you have tried this already, if so, then sorry but I can't help you more. I don't get why switchig IDEs for langs is an issue, since setting up Java + dedicated IDE is running 2 exes on Windows, but to each their own i guess^^

[subtle solstice]

This error is because you created a Java project but you didn't add a JRE to the project

so VSC doesn't know where your Java installation is

[vague oyster]

i see, how can i fix that?

[subtle solstice]

Can you go to the settings in VSC and search for Java home?

alternatively you can edit the settings.json

[vague oyster]

im trying, i thought it was supposed to use %JAVA_HOME% on windows though

[vague oyster]

this is the only thing i find

[subtle solstice]

can you open the settings as json?

look for java.home or java.jdt.ls.java.home

Also, is there a referenced libraries thing in your project?

[vague oyster]

i dont see it

[vague oyster]

no, its just the standard maven jdk8 starter project

[subtle solstice]

If you want to find the settings.json, you have to go to the VSC settings and there should be a link at the top or similar

the referenced libraries is something that should be displayed in VSC on the thing on the bottom left side

I think the view(?) should be called Java Project or similar

[vague oyster]

i see java project

[subtle solstice]

ok so there's just the Maven dependencies

Can you show the pom.xml?

ideally as text, not using an image

[subtle solstice]

Are there any options when right-clicking on jbg there? Or is there a plus sign next to it?

[vague oyster]

i can create new something

[subtle solstice]

What is there when clicking the 3 dots above?

[vague oyster]

neither configure java runtime nor classpath works however

it is fully updated

[subtle solstice]

configure Java Runtime should be the right option

[subtle solstice]

What exactly happens when clicking it?

[subtle solstice]

Did you just update it? What happens when clicking on the reload button?

[vague oyster]

this

[vague oyster]

i did try updating it, reloading it just flickers for a moment

[subtle solstice]

What happened when trying the update button?

Did you try updating the extension in the extensions tab?

Did you try restarting VSC?

[vague oyster]

it reinstalls

[vague oyster]

yeah

and restarting

[subtle solstice]

what happens when updating like that?

[subtle solstice]

Is there anything about a Java home, Java runtime configuration or similar in the project settings?

[vague oyster]

i cant, it says its fully updated

[vague oyster]

there is this

setting it to java did not change any errors

[subtle solstice]

Are you using a JDK or a JRE?

What's the output of where javac and javac -version?

[subtle solstice]

Can you try reloading the Maven project after setting that?

[vague oyster]

i did try that

[subtle solstice]

I assume it soes nothing?

does*

In your pom.xml, there is maven.compiler.source and maven.compiler.target

Both are set to 1.8

maybe try changing those to 25

or replace them with a single maven.compiler.release value set to 25

[vague oyster]

i did try, it doesnt help

[subtle solstice]

When I click on configure Java runtime in theia, I am getting this

Do you have that JDK field as well?

[vague oyster]

no, when i click configure java runtime i get this

[subtle solstice]

Can you try uninstalling and reinstalling that plugin?

Assuming reinstalling doesn't work:
Do you have this thing at the bottom? if so, can you click it and select "Open Logs"?

[vague oyster]

i do not have this

im thinking it might not work with aarm64

[subtle solstice]

oh I didn't know you are using aarm64

Maybe you could try downloading an additional x64 JDK for VSC? I think you can still run that even if it might be slower?

yeah, https://marketplace.visualstudio.com/items?itemName=redhat.java might have some issues with ARM on Windows

Are there any general logs of VSC you could look at?

[vague oyster]

not that i can tell

[subtle solstice]

maybe start VSC from cmd and check the output there?

I don't use VSC so idk

but the Java extension from Red Hat might generally not support ARM on Windows

Maybe you could try the Oracle one?

[vague oyster]

I might just use my x86 laptop instead of solving any problems

[subtle solstice]

alternatively you could also try using a different IDE

[hybrid delta]

What's so different in aarm64 that a VS code extension makes problems? Do they have to write parts of it in pure assembly?

[subtle solstice]

That's why I wanted to see the logs. My guess is that it could be something with detecting the JDK

and JDT.LS is written in Java as well so if it failed to run that, there could be a lot of issues

I don't see any logs, there's nothing in the terminal but I'm not sure if thats where it would be

[subtle solstice]

Did you open a terminal and start VSC in that terminal?

I think there are logs somewhere but idk where
