+Gradle evaluates build scripts in two phases. The first one is configuration.
+Gradle examines each task definition and execute code in definition.
+The second phase is execution where it actually executes code.
+The code is stored in doLast block. If you omit that block then println
+will execute always even when you run `gradle tasks`
