Join For FreeGradle builds are fast because Gradle supports incremental tasks. This means Gradle can determine if input or output of tasks has changed — before running the task. If nothing has changed, a task is marked as up-to-date and the task is not executed. Otherwise, the task is executed. If we want to execute a task even if it is up-to-date we must use the command line option --rerun-tasks.
In the following example, we run the assemble task for a simple Java project, and we see all tasks are executed. When we invoke the assemble task again we see the tasks are all up-to-date:
$ gradle assemble :compileJava :processResources :classes :jar :assemble
BUILD SUCCESSFUL Total time: 1.765 secs
$ gradle assemble
:compileJava UP-TO-DATE
:processResources UP-TO-DATE
:classes UP-TO-DATE
:jar UP-TO-DATE
:assemble UP-TO-DATE BUILD SUCCESSFUL
Total time: 0.715 secs
$ To run all tasks without an up-to-date check we use the option --rerun-tasks:
