Can I run a specific group of gradle tasks

I have a set of gradle tasks which can run in any order and I grouped them into 3 sets A, B and C

is there a way to run a specific group of task ? like I want to run only A only B and may be a combination of A & B

Solution

  • I think you pretty much answered it yourself, unless I am missing something :)

    You group them into aggregate tasks, and this allows you to do what you want. These tasks don't need to have any actions attached.

    For example, if you have a bunch of task like foo, bar and baz, you can group them like this:

    // Individual tasks
task foo { doLast { logger.quiet("foo!")} }
task bar { doLast { logger.quiet("bar!")} }
task baz { doLast { logger.quiet("baz!")} }

// Aggregate tasks (groups)
task A(dependsOn: ["foo", "bar"])
task B(dependsOn: ["foo", "baz"])
task C(dependsOn: ["baz"])

    Running A executes foo and bar:

    $ gradle A

> Task :bar
bar!

> Task :foo
foo!

BUILD SUCCESSFUL in 1s
2 actionable tasks: 2 executed

    Running both A and B executes them all:

    $ gradle A B

> Task :bar
bar!

> Task :foo
foo!

> Task :baz
baz!

BUILD SUCCESSFUL in 1s
3 actionable tasks: 3 executed

    Update: Sorry, didn't realize you were talking about the actual group property on tasks.

    I am pretty sure that you will still have to create a task yourself for each group, but you can simplify the dependency definition with something like this:

    A.dependsOn(tasks.matching { it.group = "A" })

    If you have many groups, you can further automate the creation of the grouping tasks like this:

    tasks.findAll{}.each { task ->
    tasks.maybeCreate(task.group).dependsOn(task)
}
