== Creating directories

Many tasks need to create directories to store the files they generate, which is why Gradle <<incremental_build.adoc#incremental_build,automatically manages>> this aspect of tasks when they explicitly define file and directory outputs.
All core Gradle tasks ensure that any output directories they need are created, if necessary, using this mechanism.
