For this purpose, to make builds faster, Gradle provides a lazy API instead: avoid using explicit dependsOn as much as you can, I tend to say that the only reasonable use case for dependsOn is for lifecycle tasks (lifecycle tasks are tasks which goal is only there to "organize the build", for example build, assemble, check: they dont do anything by themselves, they just bind a number of dependents together), if you find use cases which are not lifecycle tasks and cannot be expressed by implicit task dependencies (e.g declaring inputs instead of dependsOn), then report it to the Gradle team. Use when codeCoverageTool != None. Determining the task dependencies, that is to say what other tasks need to be executed, is done by looking up at 3 different things: the task dependsOn dependencies. Configuration of the SonarQube analysis was moved to the SonarQube or SonarCloud extensions in the task Prepare Analysis Configuration. A ComponentSelection.reject rejected the given version of the dependency.

Whatever tasks are actually used to run a task (for ex: build) can be viewed in nice HTML page using --profile option. In this case, Gradle picks the one with the most recent version.

And thats what were doing by telling from docsFileJar. This task does not satisfy any demands for subsequent tasks in the job. If multiple tasks are provides as argument of dependsOn(), the order in which they are declared does not influence the order in which they are executed. Task ordering can be useful in a number of scenarios: Enforce sequential ordering of tasks: e.g. Default value: specify. And the output is: Every dependency is applied to a specified scope.
