Grails 6 can't use classes from test in integration-test

[mattlong-finocomp]

Expected Behavior

I have a trait in src/test that contains some helper methods that have been useful in classes in src/integration-test.
In previous versions of Grails I could implement the trait on my integration-test Spec classes.

Actual Behaviour

compileIntegrationTestGroovy failed compilation as it can't resolve the class from src/test

Steps To Reproduce

1. use a generated rest-api profile (profile might not matter, but rest-api is what i used) project from start.grails.org
2. Create a Trait class in src/test/groovy named TestHelper
3. Create an integration Spec in src/integration-test/groovy and attempt to implement the TestHelper class created previously - This works in Grails 5.3.3 and earlier but not in 6.0.0

Environment Information

• OS: Pop!OS 22.04
• Java: 11

Example Application

No response

Version

See the project at https://github.com/jeffbrown/integrationtraitdemo.

src/main/groovy/com/demo/SomeTrait.groovy

package com.demo

trait SomeTrait {
}

src/integration-test/groovy/com/demo/MySpec.groovy

package com.demo

import grails.testing.mixin.integration.Integration
import spock.lang.Specification

@Integration
class MySpec extends Specification implements SomeTrait {

    void "test something"() {
        expect:
        true
    }
}

Does that build and run in your environment?

Thank you for your feedback!

FYI... At jeffscottbrown/integrationtraitdemo@50fb864 I renamed the trait to use the name specified in the initial report above in case there was something going on related to the name "*Helper".

[jeffscottbrown]

I see now that the report calls for putting the trait in src/test/, not src/main. I expect that is the relevant bit.

[mattlong-finocomp]

Yes, having the trait in src/main is fine. The regression is only on classes in src/test. This trait in particular is not something i'd want to end up in the production jar so it wouldn't make sense for us to put it in src/main.

@puneetbehl Can you provide any estimate on when there might be a 6.0.1 (or 6.1.0) grails release, or at the very least a release of the grails-gradle-plugin so that this fix can be used?
