Gradle integration is hard-coded for single-project using Java

[jnizet]

The changes made to fix #1532 still hardcodes a single default location for the classes.
This location is incorrect if Kotlin is used.
And if both Java and Kotlin are used, Gradle will store classes in two separate directories, not just one.
I don't know why the locations need to be verified that way because I have no idea of what Quarkus needs to do with these classes, but apparently:

• given that these locations are hardcoded that way, you can't run tests from the IDE (since it stores classes in a different directory than Gradle/Maven)
• you can't use any other language than Java (and Kotlin if fixed for Kotlin)
• you can't have classes and test classes in separate Gradle/Maven projects/modules

Hi, yes there are hardcoded locations for the tests in Quarkus in it's current state. This is something we will try to address asap, but it won't happen in the next release (scheduled for today). The change we've done should work for the default location though, so hopefully that works for the majority of the users.

From the latest changes in master (with this pr #1583) I successfully run the getting-started QuarkusTests from Intellij. I do not have any experience with Kotlin I'm afraid.

...looks like Gradle's quarkusDev task also follows the same trend; maybe this can be fixed along with the reported one 😎

In master, with this block in your build file:

quarkus {
    setSourceDir("src/main/kotlin")
    resourcesDir().add(File("src/main/resources"))
    setOutputDirectory("build/classes/kotlin/main")
}

Running gradle quarkusDev works, atm we're looking into fixing the plugin to work with the default values as well.

It is working with Kotlin only. But if one needs to use Kotlin and Java in one Project, this is still a big Problem.

[stalep]

Yes, that is true. We're looking into improving this inside Quarkus, but it will not be included in the upcoming release unfortunately.

Yeah, that works nice for kotlin, but i still can't seem to the get the tests running, as i can't configure the "build/classes/kotlin/test" folder for test classes anywhere. Could you please make sure to include test class configuration as well? :-)

@jkopcsek stumbled upon the same... so the problem does actually exist. I though my setup is incorrect. The build is rather complex, and uses many gradle features. My guess is quarkus generally not going well with multi-module builds. Think this is the first issue to address here.

[jkopcsek]

Here is a setup of a gradle/kotlin test that is not being recognized: https://github.com/jkopcsek/quarkus-kotlin-gradle-demo/tree/bug/quarkus-test-not-found

It is not found at all in quarkusBuild and when executing the test in IntelliJ the following error pops up:

Caused by: java.lang.RuntimeException: The test class class qkg.demo.PingResourceTest is not located in any of the directories [classes/java/test, /test-classes, bin/test]

The test classes are located in `build/classes/kotlin/test`

Did you find a way to fix this issue ? I have the same problem. I can't run my tests.

Also Quarkus doesn't support advanced Gradle configurations. Like if you put everything in implementation instead of compile it won't work (at least for sub-project/module). And https://docs.gradle.org/current/userguide/feature_variants.html
Feature variants are not supported. If I declare quarkus runtime as a feature, the server starts-up with zero extensions included. So, Gradle finds the stuff to compile, but apparently Quarkus plugin resolves configurations by name!! instead asking Gradle. So, if config name is not "compile" it doesn't consider it.
