Quarkus: Regression in 1.7.0.CR1: Maven build fails with "Failure to find org.gradle:gradle-tooling-api:jar:6.5"

[famod]

Describe the bug
Switching from 1.6.1.Final to 1.7.0.CR1 in an _existing Maven project_ results in a build failure:

[INFO] Building middleware-shared-test-quarkus 0.1.0-SNAPSHOT
[INFO] --------------------------------[ jar ]---------------------------------

Yes, this is behind a corporate Artifactory server acting as a "proxy".

Expected behavior
I can just build/test my project with Maven as before, without adding any Gradle repos.

Actual behavior
Build fails until I add https://repo.gradle.org/gradle/libs-releases to the Maven repositories in pom.xml (or to my Artifactory virtual repo).

To Reproduce
Steps to reproduce the behavior:

1. n/a at this time

Configuration
n/a

Environment (please complete the following information):

• Output of uname -a or ver: MINGW64_NT-10.0-18363 XXX 3.0.7-338.x86_64 2019-11-21 23:07 UTC x86_64 Msys
• Output of java -version: OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.7+10, mixed mode)
• GraalVM version (if different from Java): n/a
• Quarkus version or git rev: 1.7.0.CR1
• Build tool (ie. output of mvnw --version or gradlew --version): Apache Maven 3.6.3

Additional context
After adding the repo, mvn dependency:tree shows:

[INFO] +- io.quarkus:quarkus-junit5:jar:1.7.0.CR1:compile
[INFO] |  +- io.quarkus:quarkus-bootstrap-core:jar:1.7.0.CR1:compile
[INFO] |  |  +- io.quarkus:quarkus-bootstrap-app-model:jar:1.7.0.CR1:compile
[INFO] |  |  +- io.quarkus:quarkus-bootstrap-maven-resolver:jar:1.7.0.CR1:compile
[...]
[INFO] |  |  +- io.quarkus:quarkus-bootstrap-gradle-resolver:jar:1.7.0.CR1:compile
[INFO] |  |  |  \- org.gradle:gradle-tooling-api:jar:6.5:compile

It seems gradle-tooling-api 6.5 is not available via Maven central (repo1) or jcenter (these are the repos we have in our Artifactory virtual project repo).

The dependency was added here (transitively): https://github.com/quarkusio/quarkus/pull/10459/files#diff-e1d523d28b6eb842a1debab1b74c3297

I guess either the dependency has to be marked optional somehow, or the Migration Guide has to be updated to mention that you might need to add the Gradle repo.

[glefloch]

Yes this dependency is not in maven central but in a Gradle repository, I don't know how we can change this

[jaikiran]

Interesting that didn't (doesn't?) show up in our Quarkus CI jobs.

[gsmet]

Yeah, not having CI failing is very astonishing.

I'm also quite surprised we try to drag Gradle in a Maven project?

[gsmet]

@famod can you try excluding this io.quarkus:quarkus-bootstrap-gradle-resolver dependency? If it works, that would allow you to test CR1 further.

[famod]

I'll have a look tomorrow.

We have that repository somewhere, in build-parent IIRC (writing on the phone).

What puzzles me is that on my private Windows box the dependeny is found/downloaded.
So after all it might only be a problem for corporate Artifactory/Nexus "proxy" setups.
But I'll re-check that as well.

I have the same issue, even excluding it doesn't fix the issue

   > Could not find org.gradle:gradle-tooling-api:6.5.
     Searched in the following locations:
       - https://plugins.gradle.org/m2/org/gradle/gradle-tooling-api/6.5/gradle-tooling-api-6.5.pom
     If the artifact you are trying to retrieve can be found in the repository but without metadata in 'Maven POM' format, you need to adjust the 'metadataSources { ... }' of the repository declaration.

[famod]

@mahieddine Is that with a custom remote repository like Artifactory or Nexus?

[mahieddine]

@famod no i'm using jcenter/mavenCentral

[famod]

Ok, thanks. So it is a _general_ problem.

[glefloch]

This dependency is used to connect to a Gradle project in order to "discover" the project.
This allows to run tests or a main directly from the IDE.
I added the Gradle repository because this dependency provided by Gradle is not available on maven central.

[famod]

We have that repository somewhere

Root pom.xml it is: https://github.com/quarkusio/quarkus/pull/10459/files#diff-600376dffeb79835ede4a0b285078036
Please don't see this as finger pointing. I am merely gathering all info so that we can make a good decision on how to solve this.

even excluding it doesn't fix the issue

This works for me:

                </exclusion>
            </exclusions>
        </dependency>

I haven't checked dev mode yet, but I guess it should also work with this exclusion.

[gsmet]

This should be fixed in CR2 now available.

[famod]

Confirmed, thanks!
