Configuration Cache not working

Hello,

We are having a springboot application that we want to use with nebula. When running the build task with configuration-cache activated, we get the following report:

⌄⚠️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.[ ?](https://docs.gradle.org/8.5/userguide/configuration_cache.html#config_cache:requirements:disallowed_types) ⌄fieldproject📋 of nebula.plugin.release.OverrideStrategies$GradlePropertyStrategy📋 ⌄bean of type nebula.plugin.release.OverrideStrategies$GradlePropertyStrategy📋 ⌄fieldversionStrategies📋 of nebula.plugin.release.git.base.ReleasePluginExtension📋 ⌄bean of type nebula.plugin.release.git.base.ReleasePluginExtension📋 ⌄fieldthis$0📋 of nebula.plugin.release.git.base.ReleasePluginExtension$DelayedVersion📋 ⌄bean of type nebula.plugin.release.git.base.ReleasePluginExtension$DelayedVersion📋 ⌄fieldprojectVersion📋 of org.springframework.boot.gradle.tasks.bundling.BootJar📋 ■task:app:bootJar📋 of type org.springframework.boot.gradle.tasks.bundling.BootJar📋 ⌄fieldproject📋 of nebula.plugin.release.OverrideStrategies$ReleaseLastTagStrategy📋 ⌄bean of type nebula.plugin.release.OverrideStrategies$ReleaseLastTagStrategy📋 ⌄fieldversionStrategies📋 of nebula.plugin.release.git.base.ReleasePluginExtension📋 ⌄bean of type nebula.plugin.release.git.base.ReleasePluginExtension📋 ⌄fieldthis$0📋 of nebula.plugin.release.git.base.ReleasePluginExtension$DelayedVersion📋 ⌄bean of type nebula.plugin.release.git.base.ReleasePluginExtension$DelayedVersion📋 ⌄fieldprojectVersion📋 of org.springframework.boot.gradle.tasks.bundling.BootJar📋 ■task:app:bootJar📋 of type org.springframework.boot.gradle.tasks.bundling.BootJar📋 ⌄fieldproject📋 of nebula.plugin.release.git.base.ReleasePluginExtension📋 ⌄bean of type nebula.plugin.release.git.base.ReleasePluginExtension📋 ⌄fieldthis$0📋 of nebula.plugin.release.git.base.ReleasePluginExtension$DelayedVersion📋 ⌄bean of type nebula.plugin.release.git.base.ReleasePluginExtension$DelayedVersion📋 ⌄fieldprojectVersion📋 of org.springframework.boot.gradle.tasks.bundling.BootJar📋 ■task:app:bootJar📋 of type org.springframework.boot.gradle.tasks.bundling.BootJar📋 ⌄fieldvalue📋 of groovy.lang.Reference📋 ⌄bean of type groovy.lang.Reference📋 ⌄fieldproject📋 of nebula.plugin.release.NetflixOssStrategies$_developmentMetadataStrategy_closure3📋 ⌄bean of type nebula.plugin.release.NetflixOssStrategies$_developmentMetadataStrategy_closure3📋 ⌄fielddelegate📋 of org.codehaus.groovy.runtime.ConvertedClosure📋 ⌄bean of type org.codehaus.groovy.runtime.ConvertedClosure📋 ⌄fieldbuildMetadataStrategy📋 of nebula.plugin.release.git.semver.SemVerStrategy📋 ⌄bean of type nebula.plugin.release.git.semver.SemVerStrategy📋 ⌄fielddefaultVersionStrategy📋 of nebula.plugin.release.git.base.ReleasePluginExtension📋 ⌄bean of type nebula.plugin.release.git.base.ReleasePluginExtension📋 ⌄fieldthis$0📋 of nebula.plugin.release.git.base.ReleasePluginExtension$DelayedVersion📋 ⌄bean of type nebula.plugin.release.git.base.ReleasePluginExtension$DelayedVersion📋 ⌄fieldprojectVersion📋 of org.springframework.boot.gradle.tasks.bundling.BootJar📋 ■task:app:bootJar📋 of type org.springframework.boot.gradle.tasks.bundling.BootJar📋 ⌄fieldversionStrategies📋 of nebula.plugin.release.git.base.ReleasePluginExtension📋 ⌄bean of type nebula.plugin.release.git.base.ReleasePluginExtension📋 ⌄fieldthis$0📋 of nebula.plugin.release.git.base.ReleasePluginExtension$DelayedVersion📋 ⌄bean of type nebula.plugin.release.git.base.ReleasePluginExtension$DelayedVersion📋 ⌄fieldprojectVersion📋 of org.springframework.boot.gradle.tasks.bundling.BootJar📋 ■task:app:bootJar📋 of type org.springframework.boot.gradle.tasks.bundling.BootJar📋

We are using the following versions:

Nebula release: 18.0.4 (also same issue with 19.0.4)
Spring-Boot: 3.2.2

When we don't apply the nebula plugin, the configuration cache build works.

Thank you in advance

Start with the configuration-cache report and the nebula.plugin.release classes it names, especially ReleasePluginExtension, DelayedVersion, OverrideStrategies, NetflixOssStrategies, and SemVerStrategy. Reproduce the issue with the reported Nebula release and Spring Boot versions using configuration cache and the bootJar task; done means the build no longer serializes org.gradle.api.Project through those objects.
