How to pass parameters or arguments into a Gradle task?

Question

You should consider passing the -P argument in invoking Gradle.

From Gradle Documentation :

–project-prop
Sets a project property of the root project, for example -Pmyprop=myvalue. See Section 14.2, “Gradle properties and system properties”.

Considering this build.gradle

task printProp << {
    println customProp
}

Invoking Gradle -PcustomProp=myProp will give this output :

$ gradle -PcustomProp=myProp printProp
:printProp
myProp

This is the way I found to pass parameters.
