Call Gradle task with parameters inside other task - kotlin

Question

I have a Gradle task which looks like this (it collects inputs from user and then passes them to the second task):
task A() {
doFirst {
ant.input(message: "Version:", addproperty: 'version')
tasks.b "-Pversion=${ant.properties.version}" //attempt to invoke task B()
}
}
The second task just print the passed variables:
task B() {
doFirst {
println "Version: ${version}"
}
}
The problem is, that the task A does not invoke task B. I've tried with finalizedBy and doLast but I couldn't find a solution how to pass arguments while executing the task inside the other task.
When I execute the task B via command line like:
gradle B -Pversion=1.0.0
it works fine, and params are passed correctly.

Answer 1

It's not possible to 'invoke' task B from task A - Gradle tasks are not like functions.
The only way to pass data from one task to another is if
the first task saves the variables to a file,
then the second task reads the file produced by the first task.
There is an example in the docs, which you can adjust to capture user input
abstract class Producer extends DefaultTask {
#OutputFile
abstract RegularFileProperty getOutputFile()
#TaskAction
void produce() {
// capture user input
ant.input(message: "Version:", addproperty: 'version')
String message = ant.properties.version
// save the user input to a file
def output = outputFile.get().asFile
output.text = message
logger.quiet("Wrote '${message}' to ${output}")
}
}
