How to pass System Properties to Test task lazy? I tried using ValueSource as provider:

tasks.named("test", Test::class.java) { test ->
                test.systemProperty(PACT_BROKER_URL, ALPHA_PACT_BROKER_URL)
                test.systemProperty(PACT_BROKER_ENABLE_PENDING, true)
                test.systemProperty(PACT_BROKER_INCLUDE_WIP_PACTS_SINCE, "2023-10-19")
                test.systemProperty(PACT_PROVIDER_NAME, project.versionProvider.map { it[ALPHA_VERSION_FILE_PROPERTY_NAME].orEmpty() })
                test.systemProperty(PACT_PROVIDER_VERSION, project.versionProvider.map { it[ALPHA_VERSION_FILE_PROPERTY_VERSION].orEmpty() })
                test.systemProperty(PACT_PROVIDER_BRANCH, project.versionProvider.map { it[ALPHA_VERSION_FILE_PROPERTY_GIT_COMMIT_BRANCH].orEmpty() })
                test.systemProperty(PACT_VERIFIER_PUBLISH_RESULTS, System.getProperty(PACT_VERIFIER_PUBLISH_RESULTS))
            }

But in the debugger those properties are never resolved properly:

See https://github.com/gradle/gradle/issues/12247 and https://github.com/gradle/gradle/issues/9092; there are a couple workarounds there.

I was worried that this will be the same old hack that we are using for version 😉

class Version(private val version: Provider<SemVer>) {
    override fun toString(): String {
        return version.get().toString()
    }
}

Actually, you can do differently, but the

toString

-lazy also works. Hopefully with the propertization in Gradle 9 this will change anyway. The alternative you could use is an argument provider.
