Multi-project build - configure all tasks

Help/Discuss
1

My goal is to configure all tasks in a multi project build (more concretely, I want to add a system variable as an input for all tasks, such that all tasks are rebuilt whenever the value of the system variable changes).

I believe that the following code snippet should achieve this:

allprojects {
  tasks {
    inputs.property 'foo', System.properties['foo']
  }
}

But, it does not. The system property is not added as input to all my tasks.

In contrast, the following code works (where I restrict the tasks for which I configure the inputs to tasks of type AbstractTask):

allprojects {
  tasks.withType(org.gradle.api.internal.AbstractTask) {
    inputs.property 'foo', System.properties['foo']
  }
}

However, this does not look like the ‘correct’ way to achieve this (using an internal API). Can anybody help me towards a better (or even canonical) solution to this problem?

(I use gradle version 2.7 on Windows 7)

Try with

allprojects {
tasks.all {
    inputs.property 'foo', System.properties['foo']
  }
}

Thanks, it works! (And I learned something new :slight_smile: )
