Gradle Goodness: Group Similar Tasks

In Gradle we can assign a task to a group. Gradle uses the group for example in the output of $ gradle -t to output all the tasks of the same group together. We only have to set the group property with a value and our task belongs to a group.

In the following sample we add the tasks hello and bye to the group Greeting:

view sourceprint?

00.def GREETING_GROUP = 'Greeting'

01. 

02.task hello << {

03.println 'Hello Gradle!'

04.}

05.hello.group = GREETING_GROUP

06.hello.description = 'Say hello.'

07. 

08.task bye {

09.description= 'Say goodbye.'

10.group = GREETING_GROUP

11.}

12.bye << {

13.println 'Goodbye.'

14.}

If we run $ gradle -t we get the following output:

:tasks
