Gradle always does println from any task
If You have the following piece of code:
task task1 {
println 'task1 starting'
}
You're in configuration phase of a task. This phase is run during script evaluation. If You'd like to print something while task is executed You need to add an action for task.
It looks like:
task task1 << {
println 'task1 action'
}
This piece of code will be evaluated while the task is being run. <<
is exactly the same as invoking doLast
method on Task's object. You can add many actions.
EDIT I also highly encourage you to read this blog post.
from Chapter 55. The Build Lifecycle http://www.gradle.org/docs/current/userguide/build_lifecycle.html
// in `settings.gradle`
// println 'This is executed during the initialization phase.'
println 'This is executed during the configuration phase.'
task configure {
println 'This is also executed during the configuration phase.'
}
task execute << {
println 'This is executed during the execution phase.'
}
run with gradle help
output:
This is executed during the initialization phase.
This is executed during the configuration phase.
This is also executed during the configuration phase.
