Gradle: Passing variable from one task to another

I think global properties should be avoided and gradle offers you a nice way to do so by adding properties to a task:

task task1 {
     doLast {
          task1.ext.variable = "some value"
     }
}

task task2 {
    dependsOn task1
    doLast { 
        println(task1.variable)
    }
}
