[John O'Reilly]

I see that PR for JVM support (https://github.com/realm/realm-kotlin/pull/448) has been merged....is there version available to try that out?

[Claus Rørbech]

There is a 0.6.0-SNAPSHOT on Maven Central. Haven’t tried actually consuming the jvm-artifacts through Maven Central yet and only works on MacOS, but you are of course welcome to give it a try https://github.com/realm/realm-kotlin#using-snapshots

[John O'Reilly]

Getting following error when building with that....have tried with both Kotlin 1.5.30 and 1.5.31 and see same in both

hmm, noticed that README has following being used as dependency

"io.realm.kotlin:library-base:${Versions.realm}"

whereas I had been using

"io.realm.kotlin:library:${Versions.realm}"

I switched to that and getting different errors now

[John O'Reilly]

ok, fixed those (some api updates) and looking better now

[John O'Reilly]

and JVM support seems to be working nicely!

[John O'Reilly]

pushed updates to use it to https://github.com/joreilly/FantasyPremierLeague

[Nabil]

Hi @John O'Reilly I've sent a PR to bump the dependency to 0.6.0 (instead of Snapshot). The released version contains a fix for JVM Windows platform.

[John O'Reilly]

Just merged

[John O'Reilly]

I haven't looked in to this yet in any detail but I noticed that I'm getting error running Main.kt (in jvmMain in common code). The Compose for Desktop app though is working. This is the error I'm seeing

[John O'Reilly]

could be some issue in my setup

[Nabil]

which version of Studio/JVM are you running this against? it looks similar to the shadowing plugin issue https://youtrack.jetbrains.com/issue/KT-24946.
did you try with useIR = true in the common/build.gradle.kts ?

[John O'Reilly]

Using Android Studio Arctic Fox and Java 11

[John O'Reilly]

let me check that issue

[Nabil]

I assume you're trying to run the MainKt from Studio (not from command line by specifying the classpath etc.) ...

[John O'Reilly]

correct

[John O'Reilly]

if you have chance can you try and run it there

[John O'Reilly]

wonder if it could be related to this....

[John O'Reilly]

I have live coding talk in a few days so probably won't change that until that's over 🙂

[Nabil]

😄 sure. Can you please share your Run/Debug configuration?
I have the following which isn't launching anything

[Nabil]

Note: I fixed the package name of MainKt to dev.johnoreilly.common

[John O'Reilly]

message has been deleted

[John O'Reilly]

(updated package)

[John O'Reilly]

kicking off from here

[John O'Reilly]

This was something I had a while back before I started using Realm in this project so could be something else has changed as well

[John O'Reilly]

I tried various options btw under "JRE"

[Nabil]

strange ... clicking on studio doesn't run anything, I'll see if I can reproduce on another machine

[John O'Reilly]

hmm, I did fresh clone of project (+ fixed that package name) and now getting a bit further.....getting error now re.

Module with the Main dispatcher is missing.

[Nabil]

do you have the complete stack trace?

[John O'Reilly]

[John O'Reilly]

that MainScope usage might have been added to repository class since last time that code had run before

[John O'Reilly]

it must be setup for Compose for Desktop but probably not then if just running main function like this....

[John O'Reilly]

I can't remember history of why it was used in init block of FantasyPremierLeagueRepository like that....

[John O'Reilly]

I'll take a closer look later

[John O'Reilly]

as a hack I tried following and seemed to work

val dispatcher = Executors
        .newSingleThreadExecutor()
        .asCoroutineDispatcher()

    Dispatchers.setMain(dispatcher)

[John O'Reilly]

had to add kotlinx-coroutines-test to get setMain (also had to update ktor jvm driver....not fully sure why but was using that one in PeopleInSpace as well for some reason)

[John O'Reilly]

also debatable whether using repository makes sense for main function like this if we're hitting endpoints anyway (at least in terms of having the persistence functionality)

[John O'Reilly]

guess it depends on how it's going to be used

[Nabil]

BTW I added a new Console sample to double check the behaviour when using a classic Java project (not multiplatform) it seems to work both from the Intellij IDEA and as a standalone JAR https://github.com/realm/realm-kotlin-samples/tree/main/JVMConsole

[John O'Reilly]

Cool, will take a look
