Gradle throws an exception when invoking the task ':printVersion'

[d-m-h]

• Apple M1 (MacOS Sequoia 15.5)
• Gradle 8.12.1
• Experimenting with includeBuild

I'm running this on a toy project that has the following structure:

.
├── apps
│   ├── client
│   │   ├── build.gradle.kts
│   │   └── settings.gradle.kts
│   └── server
│       ├── build.gradle.kts
│       └── settings.gradle.kts
├── libs
│   └── protocol
│       ├── build.gradle.kts
│       └── settings.gradle.kts
├── build.gradle.kts
└── settings.gradle.kts

Both client and server have includeBuild("../../libs/protocol") in their settings.gradle.kts files.

When running ./gradlew :protocol:printVersion, I get this error:

./gradlew :protocol:printVersion
Calculating task graph as no cached configuration is available for tasks: :protocol:printVersion

FAILURE: Build failed with an exception.

* What went wrong:
Configuration cache problems found in this build.

5 problems were found storing the configuration cache, 4 of which seem unique.
- Build file 'libs/protocol/build.gradle.kts': external process started 'git describe --tags --always --first-parent --abbrev=7 --match=* HEAD'
  See https://docs.gradle.org/8.12.1/userguide/configuration_cache.html#config_cache:requirements:external_processes
- Build file 'libs/protocol/build.gradle.kts': external process started 'git status --porcelain'
  See https://docs.gradle.org/8.12.1/userguide/configuration_cache.html#config_cache:requirements:external_processes
- Build file 'libs/protocol/build.gradle.kts': external process started 'git version'
  See https://docs.gradle.org/8.12.1/userguide/configuration_cache.html#config_cache:requirements:external_processes
- Task `:protocol:printVersion` of type `org.gradle.api.DefaultTask`: cannot serialize object of type 'org.gradle.api.internal.project.DefaultProject', a subtype of 'org.gradle.api.Project', as these are not supported with the configuration cache.
  See https://docs.gradle.org/8.12.1/userguide/configuration_cache.html#config_cache:requirements:disallowed_types

Configuration cache entry discarded with 5 problems.

I can get around this by disabling the configuration cache, but that seems like I am just kicking the can down the road.
