in short, yes.
In Dokka 2.1.0-Beta the default value for
org.jetbrains.dokka.experimental.gradle.pluginMode
is
V2EnabledWithHelpers
. This means DGP will register 'fake', no-op tasks and configurations with the same name as those from DGPv1. (This is to ease migration, so when someone updates DGP to 2.1.0 their buildscripts will still compile if the tasks are referenced, and gives people a chance to react to deprecation warnings.)
If you don't mind these 'helper' tasks, then remove 'pluginMode'. And if you don't want them, then set
org.jetbrains.dokka.experimental.gradle.pluginMode=V2Enabled
When we remove DGPv1 (in Dokka 2.2.0?) we'll add a deprecation warning for the 'pluginMode property if it's present, so you don't have to worry about tidying it up right now.
