Publish to Maven Central?

[madhead]

Starting from May 1, 2021 JCenter will stop working. I was looking for official Koin artifacts in Maven Central and didn't find any, only some repackaged ones. Do you publish only to JCenter? Are there any plans to move away?

Describe the solution you'd like
Official Koin artifacts should be available outside of JCenter, preferably in Maven Central.

Describe alternatives you've considered

• JitPack
• GitHub Packages

Target Koin project
All of them.

[arnaudgiuliani]

Maven central also. Many Kotlin libs will go on that.

[paristote]

Will you republish previous releases too? Otherwise they won't be available anymore after May 1st, which will make it impossible to reproduce old builds.

[arnaudgiuliani]

Yes, thanks a good point 🤔

[arnaudgiuliani]

Versions are deploying on maven central: https://search.maven.org/search?q=io.insert-koin

Note that the new maven group id is io.insert-koin instead of org.koin. Others version will follow

[madhead]

BTW, you may find https://github.com/gradle-nexus/publish-plugin useful to automatically close and release staging repositories in OSSRH.

[arnaudgiuliani]

Yep. will be added for next publish 👍

Right now I'm using "org.koin:koin-android:2.2.2" and "org.koin:koin-android-viewmodel:2.2.2" in my app, but I have issues updating the last one since I can't find it here https://search.maven.org/search?q=io.insert-koin. When I use this combination: "io.insert-koin:koin-android:3.0.1-alpha-6" and "org.koin:koin-android-viewmodel:2.2.2" I get a lot of duplicate class errors. When I don't use the ViewModel library I can't use viewModel() or androidContext no more. I also tried combining the library with other libraries I found on the Maven website, but none of those make viewModel() or androidContext resolvable. Have they become deprecated? I can't find any information on that. Is there an alternative to use? Or is it included in another library?

[jameswald]

It sounds like @arnaudgiuliani is planning to deploy 2.2.2 to Maven Central as well as other previous versions. We're in the same situation now that we've dropped jcenter from our build.

[Daphne-CoffeeIT]

@jameswald I think you might have interpreted my question wrong (or I interpreted your answer wrong). I don't specifically need version 2.2.2 of any library, the newer the better 😄

But I'm not sure what @arnaudgiuliani meant by "other versions will follow". Other versions of the libraries that are currently on there, or other versions like -viewmodel and -architecture. So my question is whether a version of koin-android-viewmodel (or an alternative) will be available on Maven too, it doesn't really matter which version as long as viewModel() or androidContext are supported.

[xsveda]

@DaphnevdVeeke koin-android-viewmodel artifact does not exist anymore in newer versions, it was merged to koin-android in 3.0.1-alpha-3. Thats the root of duplications you experience, the io.insert-koin:koin-android:3.0.1-alpha-6 artifact should be all you need.
See https://github.com/InsertKoinIO/koin/blob/master/CHANGELOG.md

[Daphne-CoffeeIT]

@xsveda I saw that, but then how to we use org.koin.android.viewmodel.dsl.viewModel or an equivalent reference? It's not in there, unfortunately.

Update: seems like auto import is just broken and I had to do a little guessing game, which I didn't realise yesterday night. I've got it working now. For the modules I'm able to use import org.koin.androidx.viewmodel.dsl.viewModel instead and in the fragments import org.koin.androidx.viewmodel.ext.android.viewModel. I hope this helps other people as well!

[matsujun]

Not only previous version but also current (stable) version is not exist on maven central...
There are only alpha version on maven central...

[arnaudgiuliani]

current is beta-1: https://search.maven.org/search?q=io.insert-koin

[matsujun]

Beta is NOT stable version.

[jakoss]

I think the historical versions are crucial for a lot of people. Not everybody can upgrade just like that

[arnaudgiuliani]

sure, I will repush them for Q2.

[dendrocyte]

I ref. https://insert-koin.io/docs/setup/v3/ and change to MavenCentral, but found stateViewModel is not available to use.

[arnaudgiuliani]

it should be available in koin-android package

[arnaudgiuliani]

2.0.1, 2.1.6 & 2.2.2 have been pushed to Maven Central, as well as 3.x versions.

[soniamca17]

Its not working I am not able to use the dependency - org.koin:koin-android:2.1.6 from mavenCentral. Please help.

[OrangeDog]

@soniamca17

Note that the new maven group id is io.insert-koin instead of org.koin.

[jbvincey]

@arnaudgiuliani the documentation https://insert-koin.io/docs/setup/v2/ is not up-to-date. It points to mavenCentral but still references the group id org.koin. Could you update the documentation?
Thanks in advance 🙏

[arnaudgiuliani]

Arf yes. Thanks @jbvincey, it's deploying

[arnaudgiuliani]

@soniamca17 the goup id is now "io.insert-koin" and not "org.koin"

[tasomaniac]

In case the koin runtime dependency comes transitively from another dependency, the above suggestions may not be too easy to do. In case someone hits this issue, I'm leaving a solution that I found with Gradle.

It basically dynamically substitutes all of the org.koin dependencies with io.insert-koin while keeping the module name and versions intact. This might help you remove jcenter even if your dependency did not update koin yet.

    configurations.all {
        resolutionStrategy {

            dependencySubstitution {
                all {
                    val requested = this.requested as? ModuleComponentSelector
                    if (requested != null && requested.group == "org.koin") {
                        useTarget("io.insert-koin:${requested.module}:${requested.version}")
                    }
                }
            }
        }
    }
