Bloop: Missing scala 2.12 artifacts for gradle-bloop

Created on 8 Aug 2018 · 8Comments · Source: scalacenter/bloop

jcenter has gradle-bloop 1.0.0+37-ad2ae774 for scala 2.11:

https://jcenter.bintray.com/ch/epfl/scala/gradle-bloop_2.11/

but nothing for 2.12:
https://jcenter.bintray.com/ch/epfl/scala/gradle-bloop_2.12/

and no 'gradle-bloop' in maven central:
http://repo1.maven.org/maven2/ch/epfl/scala/

bug gradle has fix

For wandering travelers who find this page, the gradle bloop 2.12 plugin is named differently:

Yes, this is on purpose, given that classloading 2.12 in Gradle gave problems.

Re the resolution issue: it looks like the artifacts haven't yet hit Maven Central even though they were released one day and a half ago. However, you can release it by adding our repo to the buildscript in the meanwhile. A proof that it works:

The bintray repo referred in my previous comment can be found in https://bintray.com/scalacenter/releases/bloop/.

Using a 2.11 plugin won't work for 2.12 projects, since they'll already have the 2.12 runtime in gradle's classpath for other scala plugins (scalastyle, scoverage, etc).

Here's what happens when I use the 2.11 gradle-bloop plugin in my 2.12 project:

$ ./gradlew bloopInstall -iS
...
> Configure project :
Evaluating root project ...

Applying bloop plugin to project ...

FAILURE: Build failed with an exception.

* Where:
Build file '.../build.gradle.kts' line: 1

Using a 2.11 plugin won't work for 2.12 projects, since they'll already have the 2.12 runtime in gradle's classpath for other scala plugins (scalastyle, scoverage, etc).

Are you sure? All these plugins you've mentioned use the Scala 2.11 runtime: https://github.com/ngbinh/gradle-scalastyle-plugin, https://github.com/scoverage/gradle-scoverage. I think that what's causing the conflict is likely another plugin in your buildpath. I think it would be helpful to identify what's the responsible.

Anyhow, I was trusting gradle to do something reasonable here and keep independent class loaders for plugins -- this is disappointing. Our plugin for gradle already cross-compiles to 2.12 and 2.11, so we can certainly publish a 2.12 artifact as fix but before we do could you clone the repo, follow the contributing guide, publish local gradle with the changed version, and make sure that a 2.12 version of the plugin works in your build?

@jvican Publishing a 2.12 version to my local repo worked for my 2.12 project.

I found a few issues in the process and submitted a few proposed fixes:
