is there any way to use the ad hoc tasks API to add a command line

@Option

to a task? My use-case is in an Android project. It has tasks like

testDebugUnitTest

and

testReleaseUnitTest

, as well as a lifecycle task

test

that depends on each of those two variant-specific Test tasks. I would love to add a

--tests

option to this preexisting (from another plugin, I do not control it)

test

lifecycle task. I've tried this, but it doesn't work:

project.tasks.named { it == "test" }.configureEach {
  inputs
    .property("tests", "") // passing no value as a test
    .optional(true)
}

I still get

> Unknown command-line option '--tests'.

I thought there was an issue about this but I can't find it

alternatively, the perennial idea of "replacing a task" would help here

It's not as nice a a command line options, but what you can do is define a project property that you can pass via -P. The benefit of this is that you can call a lifecycle task but still have another task in the graph evaluate the property.

I have a working proof of concept intended for Android projects that parses the command line and injects the tests option via extra properties (IP safe). It configures test tasks directly with

task.setTestNameIncludePatterns(/* value from extra properties */)

. Maybe too clever? It works though

if it works, it works 🤷‍♂️

here's the source code for my new (unpublished) Gradle plugin for Android, "dedebug" (de-debug, removing the debug build type from Android libraries). Also handles this

--tests

case, which is why I thought it interesting enough to wrap up in a plugin https://github.com/autonomousapps/dedebug
