How to pass a property collection to Gradle

Question

I would like to use the properties injection of command line Gradle to pass it an array, is this possible?

Something like this:

gradle build -PmyProp=['value1','value2','value3']

And access it like usual:

if(project.hasProperty('myProp')) {
    for ( prop in myProp ) {
        ...
    }
}

Is this possible?

Answer 1

You cannot pass array as value of a property. However you can accept a comma separated string as value and split inside your gradle file.

if (project.hasProperty('myProp')) {
    project.properties['myProp'].split(',').each { 
        println it
    }
}

Run as gradle build -PmyProp=value1,value2,value3
