Function from init.gradle in build script

Question

in my init.gradle I have

...
// the last thing in init.gradle
def buildTime() {
   def df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'") //you can change it
   df.setTimeZone(TimeZone.getTimeZone("UTC"))
   return df.format(new Date())
} 

In my build.gradle I want to do something like this:

task showTime() << {
    println buildTime()
}

But I get "Could not find method buildTime() for arguments [] on root project..."

Thx in advance!

The init file is a different context than the build.gradle file. But you can extend a project object (build.gradle delegates to) with a custom property or method (using a closure):

init.gradle

import java.text.SimpleDateFormat
gradle.allprojects{
  ext.buildTime = {
   def df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'")
   df.setTimeZone(TimeZone.getTimeZone("UTC"))
   return df.format(new Date())
   }    
}

build.gradle

task showBuildTime() << {
   println buildTime()
}
