@Imran/Malic i’ve found a pretty embarassing bug in arrow-integrations-jackson-module - seems like that’s released for java 15 source compatibility. it works on maven but fails on gradle. 😭 https://github.com/arrow-kt/arrow-integrations/pull/93

Related to this: https://kotlinlang.slack.com/archives/C19FD9681/p1652816267741679

@Javier what version was the gradle config which has the fix previously? i remember there was a renovate pr bump for arrow-gradle-config a while back. What I know is the latest alpha.15 of arrow-integrations-jackson was using

0.10.2

. I needed to add java / toolchain to java 8 specifically in the corresponding module.

Feels free to create a PR in arrow-gradle-config with that fix if you want 🙂

Arrow integrations has its CI with Java 15 so we need to change that

right..

AFAIK arrow-gradle doesnt need changes for that

@Imran/Malic that is good IMO, the problem is Kotlin has a bug which has been solved

Do you know if it comes in 1.7 ? Or is already in 1.6.21?

we added the workaround mentioned in the issue, but as @mitch is mentioning, it looks like it is not working

Arrow gradle in arrow-integrations isnt on the alpha release we published this week

yeah, with 1.7 those properties don't exist (we have tried to add arrow gradle config to arrow inject and we got that crash)

ohh

I think we should avoid publishing alphas in arrow gradle config

the alphas are really helpful

yeah @mitch, but I mean only for the arrow gradle config repo, rest will keep them 🙂

I think we should avoid publishing alphas in arrow gradle config

i think both is fine I was publishing an alpha since we wanted to get the release out for arrow-endpoints and I wasn‘t sure if it works

ahh okay

But arrow-endpoints alpha was published successfully, so we can publish a new stable version

but it is sucessfully pubolished with Gradle metadata wrong, no?

looking at arrow-endpoints, it does use

arrowGradleConfig = "0.10.3-alpha.1"

and

- name: Set up Java
        uses: actions/setup-java@v3.1.0
        with:
          distribution: 'adopt'
          java-version: '15'

looks like there’s no java/toolchain mentions

yeah we used the another workaround

oh this one? https://youtrack.jetbrains.com/issue/KT-45335/kotlinOptions-jvmTarget-conflicts-with-Gradle-variants#focus=Comments-27-4765781.0-0

configurations["runtimeElements"].attributes {
    attribute(TargetJvmVersion.TARGET_JVM_VERSION_ATTRIBUTE, 8)
}

or this other one? https://youtrack.jetbrains.com/issue/KT-52474/An-attribute-org-gradle-jvm-version-isn-t-set-correctly-while-up#focus=Comments-27-6102307.0-0 alt 1?

tasks.withType(JavaCompile::class.java) {
    targetCompatibility = "1.8"
    sourceCompatibility = "1.8"
}

or alt2? java toolchain

kotlin {
    jvmToolchain {
        languageVersion.set(JavaLanguageVersion.of(8))
    }
}

@mitch the workaround was in 0.10.3-alpha.2

right..

and we don't know if it works yet

ah right i see your pr https://github.com/arrow-kt/arrow-gradle-config/pull/54/files

I will create a PR in arrow gradle config but if you want feels free to create it :)

ok @Imran/Malic @Javier i’m going to check out for now, it’s almost midnight here. Will touch base again in the morning. 🤞 hopefully that’s enough data point. I’m quite convinced we need to use java / toolchain

okay, really thank you for your help ;)

Thanks @mitch for the insight :)

Oh right java / toolchain might not be needed i just realised we just need to set the apiElements as well

i think java toolchain looks cleaner than the current workaround

i yolo-ed a PR to add apiElements https://github.com/arrow-kt/arrow-gradle-config/pull/58

we can merge it and do an alpha release

🤞

depending on the status of mavencentral servers, it should be available in 10-20 min

i’m gonna sleep for now and try in the morning while i bake my bread

which command are you running to check the variants version?

outgoingVariants

nice, thank you! see you 🙂

that’s awesome! is that alpha.3 ?

@mitch did it work?

Yep it does! 🙌

Awesome thanks @mitch for raising this up
