How should I fix this problem with the configuration cache in a settings plugin? It is related to the function

onlyIf

in the new develocity plugin

WARNING: Error invoking build scan publishingCondition action
        Parameter specified as non-null is null: method com.javiersc.hubdle.settings.HubdleSettingsPluginKt.getHubdleSettings, parameter <this>

The relevant code is:

public val publishAlways: Property<Boolean> =
    objects.property<Boolean>().convention(System.getenv("CI") == "true")

private fun Settings.configureGradleDevelocity() {
    pluginManager.apply("com.gradle.develocity")
    
    configure<DevelocityConfiguration> {
        buildScan { scan ->
            scan.publishing.onlyIf { hubdleSettings.buildScan.publishAlways.get() }
        }
    }
}

The infamous "name punning" may help, though I'm surprised you hadn't hit any serialization problems:

private fun Settings.configureGradleDevelocity() {
    pluginManager.apply("com.gradle.develocity")
    
    val publishAlways = hubdleSettings.buildScan.publishAlways
    configure<DevelocityConfiguration> {
        buildScan { scan ->
            scan.publishing.onlyIf { publishAlways.get() }
        }
    }
}

Can you please prepare a minimal reproducer for us to investigate further?

I am facing another issue now, I will try it when I fix the current one which is blocking me to test that, sorry and thank you!

There is no con about this? (edited)

Well, CC has to store the whole provider chain to re-evaluate it upon loading, but the overhead is likely tiny, unless you have thousands of these properties laying around.

your workaround work 🙂 Do you still need a repro?

I suppose, what you're seeing is another consequence of

problems=warn

, in which case there's no need for the reproducer. Thank you for cooperation!
