However, mutable types like `Property` are designed to track dependencies and origin of values they are supplied with.
As a consequence, it is an error to make them overwritable, because Gradle will then be unable to tell where a property value comes from.

To fix this problem, you should either make your property final and remove the setter:

```groovy
class MyTask extends DefaultTask {
    @Input
    final Property<Integer> getX() = ...

#   WHAT: List of checks to run
#
# Example:
#   make verify
#   make verify BRANCH=branch_x
#   make verify WHAT="gofmt typecheck"
endef
.PHONY: verify
ifeq ($(PRINT_HELP),y)
verify:
	echo "$$VERIFY_HELP_INFO"
else ifeq ($(origin KUBE_VERIFY_GIT_BRANCH), undefined)
verify:
	KUBE_VERIFY_GIT_BRANCH=$(BRANCH) hack/make-rules/verify.sh
else
verify:
	hack/make-rules/verify.sh
endif

Gradle recommends that you place sources in directories according to their language, because builds are more performant and both the user and build can make stronger assumptions.

The following source tree contains Java and Kotlin source files. Java source files live in `src/main/java`, whereas Kotlin source files live in `src/main/kotlin`.

A complex and highly dynamic build may require some restructuring anyway, so in such cases reimplementing build logic to follow Gradle best practice makes sense.

Since applying Gradle best practices will make your builds easier to use and faster, we recommend that you migrate all projects in that way eventually, but it makes sense to focus on the projects that have to be restructured first and those that would benefit most from the improvements.

 * Separate API and implementation JARs — it may make sense to have these as separate projects, particularly if you already have a multi-project build
 * Generated sources — if the resulting sources should be compiled with the production code, add their path(s) to the `main` source set and make sure that the `compileJava` task depends on the task that generates the sources

Inspecting provides a comparison point to better understand the impact of the changes recommended on this page.

To best make use of this page:

. Inspect your build.
. Make a change.
. Inspect your build again.

If the change improved build times, make it permanent. If you don't see an improvement, remove the change and try another.
