Incompatibility with gradle configuration cache

[Spikhalskiy]

When attempting to enable gradle configuration cache in a project with this plugin applied, the build fails with

Configuration cache entry discarded with 1 problem.
FAILURE: Build failed with an exception.

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

1 problem was found storing the configuration cache.
- Task `:coverallsJacoco` 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/8.4/userguide/configuration_cache.html#config_cache:requirements:disallowed_types

Gradle Configuration Cache is an experimental feature that is turned off by default, but most major plugins at this moment already support it. It would be great to see Coveralls plugin supporting it too. https://docs.gradle.org/current/userguide/configuration_cache.html

The problem still exists in 1.2.18

Yeah, I was hoping for a reproducible example for this use case to help fix this one.
