Got empty license reports with hierynomus' gradle license plugin - gradle

Question

I'm making two android apps on a Gradle project and managing dependency licenses with Hierynomus' gradle license plugin.
Then, I executed following commands:
$ ./gradlew downloadLicenses
$ cat ./build/reports/license/dependency-license.json
But the generated license reports are empty.
{"dependencies":[]}
I tried to fix the problem with the documents below:
https://github.com/hierynomus/license-gradle-plugin/issues/81
https://github.com/hierynomus/license-gradle-plugin/issues/103
https://github.com/hierynomus/license-gradle-plugin/issues/137
https://github.com/hierynomus/license-gradle-plugin/issues/174
but I couldn't resolve the problem.
Next, I tried to execute the task with --refresh-dependencies and --rerun-tasks options. Sadly, the problem hadn't fixed.
Those are my build scripts:
// build.gradle
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {

No doubt I expected dependencies license reports of my project were generated under ${PROJECT_ROOT}/build/reports/license/. I found the reports are generated, however, those were empty.
Thanks!

Answer 1

It seems to be a problem with version 0.15.0 Fix getting licenses on Android.
For me, it worked with version 0.14.0 and some additional configurations:
// buil.gradle root
plugins {
id "com.github.hierynomus.license" version "0.14.0"
}
downloadLicenses {
dependencyConfiguration = 'implementation'
includeProjectDependencies = true
}
// build.gradle app
apply plugin: 'com.github.hierynomus.license'
configurations.implementation.setCanBeResolved(true)
configurations.api.setCanBeResolved(true)
