Plugin incompatible with modern Gradle

[bpfoster]

This thing was cool back in its day, but it's 2024 and the world has progressed, buddy.

Attempting to use this with a modern Gradle version (e.g. 8.8) does not work.

A problem occurred evaluating root project 'gradleapi'.
> Plugin with id 'maven' not found.

Take out the removed maven plugin and:

A problem occurred evaluating root project 'gradleapi'.
> Could not find method compile() for arguments [org.gradle.api.internal.artifacts.dependencies.DefaultFileCollectionDependency_Decorated@5f19829b] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

If I resolve that, then I get a deprecation warning:

Build file '/home/devman/dev/third-party/gradleapi/build.gradle': line 16
The RepositoryHandler.jcenter() method has been deprecated. This is scheduled to be removed in Gradle 9.0. JFrog announced JCenter's sunset in February 2021. Use mavenCentral() instead.

If I resolve that, then I get a compile error:
