Passing property values on the command line is particularly helpful if they change more frequently.

The task API supports a mechanism for marking a property to automatically generate a corresponding command line parameter with a specific name at runtime.

[[sec:hidden_tasks]]
== Private and hidden tasks

Gradle doesn't support marking a task as _private_.

However, tasks will only show up when running `:tasks` if `task.group` is set or no other task depends on it.

	span.freeIndexForScan = span.freeindex

	// Allocate black during GC.
	// All slots hold nil so no scanning is needed.
	// This may be racing with GC so do it atomically if there can be
	// a race marking the bit.
	if gcphase != _GCoff {
		gcmarknewobject(span, uintptr(x))
	}

	if raceenabled {
		racemalloc(x, size)
	}

	if msanenabled {
		msanmalloc(x, size)
	}

In order to handle volatile inputs for your tasks consider <<incremental_build.adoc#sec:configure_input_normalization,configuring input normalization>>.

[[sec:task_output_caching_disabled_by_default]]
=== Marking tasks as non-cacheable by default

There are certain tasks that don't benefit from using the build cache.
One example is a task that only moves data around the file system, like a `Copy` task.
