Add support for Gradle's configuration cache

[sergeys-opera]

licenseReport task doesn't support Gradle's configuration cache.

This is what I get when I enable the configuration cache for my project:

2015 problems were found storing the configuration cache, 9 of which seem unique.
- Plugin 'com.android.internal.library': execution of task ':ui:licenseProductionReport' caused invocation of 'Task.project' in other task at execution time which is unsupported.
  See https://docs.gradle.org/8.1.1/userguide/configuration_cache.html#config_cache:requirements:use_project_during_execution
- Plugin 'com.android.internal.library': execution of task ':ui:licenseReleaseReport' caused invocation of 'Task.project' in other task at execution time which is unsupported.
  See https://docs.gradle.org/8.1.1/userguide/configuration_cache.html#config_cache:requirements:use_project_during_execution
- Task `:ui:licenseDebugReport` of type `com.jaredsburrows.license.LicenseReportTask`: invocation of 'Task.project' at execution time is unsupported.
  See https://docs.gradle.org/8.1.1/userguide/configuration_cache.html#config_cache:requirements:use_project_during_execution
...

Configuration cache significantly improves the build times and it would be nice to get it work with the license plugin.

Yeah, would be great to be able to enable the configuration cache.
Just wondering what are the necessary steps to modify the plugin to support it.
I could potentially fork it and do it myself since it's been a few months already without updates.

I was working on this here - #217

Oh, interesting. And what's left to do? And did you decide to stop working on it?
Sorry for the questions, not experienced at all with developing Gradle plugin but trying to research how to fix this myself.

Hi @jaredsburrows, we are doing a survey at @gradle rounding up plugins supporting or planning to support configuration cache.
I can see your PR has been in the making for quite a while. What are your current plans for supporting CC?

[jaredsburrows]

@hegyibalint I plan on working on it soon

As a workaround, you can add:

tasks.matching { it.name.startsWith("license") }.configureEach {
    notCompatibleWithConfigurationCache("LicenseReportTask uses Task.project at execution time")
}
