between these two syntaxes is, that the configuration block of an registered task will only be executed when the task is actually created due to the build requires that task to run. The configuration block of an eagerly created tasks will be executed immediately.

By actually doing less in the gradle configuration time as only creating tasks that are requested as part of the build and by only running the configurations for those requested tasks, using the task avoidance api contributes a major part...
