In other words, the configuration cache saves the output of the configuration phase, and the build cache saves the outputs of the execution phase.

[IMPORTANT]
====
This feature is currently not enabled by default. This feature has the following limitations:

    query_item: string for feature related to the variable, e.g. "CUDA for
      Nvidia GPUs".
    enabled_by_default: boolean for default behavior.
    question: optional string for how to ask for user input.
    yes_reply: optional string for reply when feature is enabled.
    no_reply: optional string for reply when feature is disabled.

  Returns:
    boolean value of the variable.

all the source files again or just the modified one? That depends on the task implementation. If the latter, then the task itself is incremental, but that’s a different feature to the one we’re discussing here. Gradle does help task implementers with this via its <<custom_tasks.adoc#incremental_tasks,incremental task inputs>> feature.

Now that you have seen some of the input and output annotations in practice, let’s take a look at all the annotations available to you and when you should...
