Java Test Runner not recording any test output

When I first try to execute all JUnit tests, I receive this on the Debug Console:

After cleaning the Gradle project with "./gradlew clean build --refresh-dependencies" and trying to run the tests again, it tells me that my build has failed.

Here is my current build.gradle.kts file:

plugins {
    // Apply the application plugin to add support for building a CLI application in Java.
    id("java")
    application
    id("org.openjfx.javafxplugin") version "0.1.0"
}

repositories {
    // Use Maven Central for resolving dependencies.
    mavenCentral()
}

dependencies {
    // Use JUnit Jupiter for testing.
    testImplementation(platform("org.junit:junit-bom:5.10.0"))
    testImplementation("org.junit.jupiter:junit-jupiter")
    // https://mvnrepository.com/artifact/org.mockito/mockito-core
    testImplementation("org.mockito:mockito-junit-jupiter:5.15.+")
}

// Apply a specific Java toolchain to ease working on different environments.
java {
    toolchain {
        languageVersion = JavaLanguageVersion.of(21)
    }
    sourceSets {
        named("main") {
            java {
                setSrcDirs(listOf("src/main/java"))
            }
        }
    }
}

javafx {
    version = "21.0.6"
    modules("javafx.controls", "javafx.fxml")
}

application {
    // Define the main class for the application.
    mainClass = "main"
}

tasks.named<Test>("test") {
    // Use JUnit Platform for unit tests.
    useJUnitPlatform()
}

I tried reloading my project, cleaning java language workspace etc. nothing seemed to change anything.
Important to note is that on a completely different cloned repository with the same gradle configurations, everything works fine.

Would appreciate any help with this, otherwise I'll stick to IntelliJ with the testing.

The report points to the Java Test Runner and the project's build.gradle.kts, with JUnit tests invoked through Gradle. Start by reproducing the test run and reviewing the Debug Console and Gradle build output; done means identifying why this project records no test output and restoring successful test execution.
