* Where:
Build file '/Users/cnygard/src/gradle-docker/build.gradle' line: 29

* What went wrong:
A problem occurred evaluating root project 'gradle-docker'.
> Failed to apply plugin class 'com.palantir.configurationresolver.ConfigurationResolverPlugin'.
   > Could not create task ':resolveConfigurations'.
      > Cannot create task ':resolveConfigurations' of type 'ResolveConfigurationsTask' as directly extending AbstractTask is not supported.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

Deprecated Gradle features were used in this build, making it incompatible with Gradle 8.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

See https://docs.gradle.org/7.1/userguide/command_line_interface.html#sec:command_line_warnings

What did you want to happen?

Be able to develop gradle-docker against Gradle 7.1, and update configurationResolver code to resolve issues noted above. Since configuration resolver code is archived, I'm unsure what your plans are for this plugin.
