Test framework configuration fails with Gradle 7.3

[melix]

Expected Behavior

A project generated from Launch should work out of the box using Gradle 7.3.

Actual Behaviour

Running the build fails with:

A problem occurred configuring root project 'demo'.

The value for task ':test' property 'testFrameworkProperty' is final and cannot be changed any further.

The stack trace leads to another ordering issue in the Gradle plugin:

        at io.micronaut.gradle.MicronautLibraryPlugin.lambda$apply$4(MicronautLibraryPlugin.java:101)
        at org.gradle.configuration.internal.DefaultUserCodeApplicationContext$CurrentApplication$1.execute(DefaultUserCodeApplicationContext.java:123)
        at org.gradle.configuration.internal.DefaultListenerBuildOperationDecorator$BuildOperationEmittingAction$1.run(DefaultListenerBuildOperationDecorator.java:152)

Steps To Reproduce

Create a Gradle project using Micronaut Launch, don't specify any testing framework.
Run the build with Gradle 7.3-rc-3, see it fail.

Workaround is to add:

tasks.withType(Test).configureEach {
	useJUnitPlatform()
}

to the build file.

Got the same error when upgrading to Gradle 7.3.

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'demo'.
> The value for task ':test' property 'testFrameworkProperty' is final and cannot be changed any further.

Also seeing the same problem. We're using Micronaut 2.5.12 and the plugin 1.5.4 on AdoptOpenJDK 8, and get the same failure trying to upgrade to Gradle 7.3. I also get the same problem creating Micronaut 2 or 3 apps in Launch and upgrading them to Gradle 7.3.

On our projects we're using the Gradle 7 version catalog feature across all our projects, so it's in our best interest to track these Gradle upgrades, but this issue is a blocker for that. I will try the workaround noted above.

This is the error I get upgrading a default Launch project (3.1.3, JDK8, JUnit5):

% ./gradlew wrapper --gradle-version=7.3
FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'gradle73FailWithMn3'.
> The value for task ':test' property 'testFrameworkProperty' is final and cannot be changed any further.

We ran into the same issue.
Looks like gradle did something I NEVER expected to happen for a patch release: They changed behavior:

This is going to be changed on the Gradle side. See: gradle/gradle#19058

I understand that Gradle is going to revert the change, but I'm not sure how we can prepare for the change in 8.0. Basically, we have this code:

micronaut-gradle-plugin/src/main/java/io/micronaut/gradle/MicronautLibraryPlugin.java

Lines 99 to 106 in a8161de

	if (testRuntime != MicronautTestRuntime.NONE) {
	// set JUnit 5 platform
	project.getTasks().withType(Test.class, test -> {
	if (!test.getTestFramework().getClass().getName().contains("JUnitPlatform")) {
	test.useJUnitPlatform();
	}
	});
	}

which is executed in an afterEvaluate. The idea is to say "if the user didn't configure a specific test framework, use JUnit Platform". It has to be executed in an afterEvaluate because we don't know when the user is "done" with configuration. I also understand that this is basically broken because if the user configures test options, then they would be ignored when this is called.

An option would be to configure useJUnitPlatform(), but if the test framework is set, change it.
