Upgrade to Quarkus 3.1 fails with Gradle errors

[peterfortuin]

Describe the bug

When I upgrade my microservices from Quarkus 3.0 to 3.1 I get the following error in Gradle:

It's kinda weird, since the missing references are just basic Gradle functions that should always be there.

Expected behavior

I expect to be able to upgrade from Quarkus 3.0 to 3.1 without any issues.

Actual behavior

I get an error message in Gradle about unresolved references.

How to Reproduce?

Steps to reproduce:

1. Have a Quarkus 3.0.4.Final project.
2. Upgrade to Quarkus 3.1.0.Final.

Output of uname -a or ver

Darwin Macbook.local 22.3.0 Darwin Kernel Version 22.3.0: Thu Jan 5 20:48:54 PST 2023; root:xnu-8792.81.2~2/RELEASE_ARM64_T6000 arm64

Output of java -version

java version "17.0.2" 2022-01-18 LTS Java(TM) SE Runtime Environment (build 17.0.2+8-LTS-86) Java HotSpot(TM) 64-Bit Server VM (build 17.0.2+8-LTS-86, mixed mode, sharing)

GraalVM version (if different from Java)

Not installed

Quarkus version or git rev

3.1.0.Final

Build tool (ie. output of mvnw --version or gradlew --version)

Gradle 7.5.1

Additional information

I think it has something to do with the use of the gradle-application-plugin:

implementation("io.quarkus:gradle-application-plugin:3.1.0.Final")

What happens if you upgrade the Gradle wrapper to 8.1.1? See https://gradle.org/install/#with-the-gradle-wrapper

It seems that will give me another problem that I need to investigate.

[peterfortuin]

After resolving some problems I was able to use Gradle 8.1.1 to build my project. And with Gradle 8.1.1 I had no issues with Quarkus 3.1.0. So, my problem is resolved.
Thank you for your time and effort.
