groovy - How to use gradle properties in build.gradle -

when run task:

task tmptask << {     project.properties.each {println "   $it"} }

i see:

org.gradle.java.home=/usr/lib/jvm/java-6-oracle

but how use variable? i've tried both:

task tmptask << {     println org.gradle.java.home     println project.properties.org.gradle.java.home }

but none of works. first print gives error:

could not find property 'org' on task ':tmptask'.

while second fails with:

cannot property 'gradle' on null object

so can use

project.properties['org.gradle.java.home']

you can use property() method (but looks in additional locations):

project.property('org.gradle.java.home')
