Should the instructions work with Gradle 7.3-rc-1?

[Miles-Garnsey]

I'm interested in trying out Quarkus in Scala 3 and am hitting a build issue. I'm using the gradle build referenced in the PR that the README mentions, so I should have the required level of Scala 3 support in gradle.

I still get back an error: Plugin [id: 'io.quarkus'] was not found in any of the following sources.

Should this currently be working? I have tried with the 7.3-rc-1 release as well.

[GavinRay97]

Hey, so sorry for the late reply!

Yes, you're right. It should work with the latest Gradle RC's, and I need to update the build instructions for this.

Due to some changes that Tomasz made with the way Bloop/Metals works, the entire section with the manual bloop plugin should also not be necessary.

Will update it ASAP to latest instructions, remove unnecessary bits, and also try to put up a working example repo if I have some time.

[GavinRay97]

Okay, I've updated the README, will try to put together a Gradle + Maven starter that works out-of-the-box

[Miles-Garnsey]

Thanks for coming back to me @GavinRay97! I do still seem to get the same error. On the following gradle version now:

distributionUrl=https://services.gradle.org/distributions/gradle-7.3-rc-3-bin.zip

[Miles-Garnsey]

I almost got it working by using id "io.quarkus" version "2.4.1.Final" (it was kind of doing a lot of work downloading packages anyway...)

But then I got this error instead:

A problem occurred evaluating root project 'scala3-gradle'.
> Could not set unknown property 'VERSIONS' for root project 'scala3-gradle' of type org.gradle.api.Project.

[Miles-Garnsey]

After upgrading to Gradle 7.3.3 I've started getting some more informative error messages. I think I've narrowed this problem down to some combination of the following -

• It seems that the quarkus.io plugin doesn't like Java 8, now using 11.
• Defined a specific quarkus.io version number in plugins - id "io.quarkus" version "2.6.1.Final" so that Gradle can find the plugin.
• Variables quarkusPlatformGroupId, quarkusPlatformArtifactId, quarkusPlatformVersion were not found (I think I needed a gradle.properties in there somewhere), use hardcoded implementation(enforcedPlatform("io.quarkus:quarkus-bom:2.6.1.Final")) to work around this temporarily.
• Gradle couldn't find Jackson components of version 2.12.3, using 2.13.1 instead.
• Add def to VERSIONS [...] declaration.

I don't 100% know what I'm doing with some of these changes (e.g. why VERSIONS didn't originally need a def keyword) but this now works for me.

Not sure if you'd like to incorporate any of these changes into your README @GavinRay97 or if they are completely misguided!
