Java – gradle always executes println from any task

I have a simple build Gradle (or build. Gradle for any task with println)

println GradLeversion.current().prettyPrint()

task task1{
    println 'task1 starting'
}

Now, when I run $gradle build, I always see the task or printout being executed

task1 starting
:compileJava UP-TO-DATE
:processResources UP-TO-DATE
:classes UP-TO-DATE
:jar
:assemble
:compileTestJava UP-TO-DATE
:processTestResources UP-TO-DATE
:testClasses UP-TO-DATE
:test UP-TO-DATE
:check UP-TO-DATE
:build

BUILD SUCCESSFUL

Why does the task in println always have output?

Solution

If you have the following code:

task task1 {
    println 'task1 starting'
}

You are in the configuration phase of the task This phase runs during script evaluation If you want to print something while executing a task, you need to add an action to the task

Look like:

task task1 << {
   println 'task1 action'
}

This code is evaluated when the task is run<< It is exactly the same as calling the dolast method on the task object You can add many actions
