Project#afterEvaluate cannot be executed in the current context

[mjulianotq]

Shadow Version

7.0.0

Gradle Version

7.0.2

Expected Behavior

Gradle evaluates its configuration correctly.

Actual Behavior

Gradle fails to configure a project with this plugin because of the call to Project#afterEvaluate.

* What went wrong:
An exception occurred applying plugin request [id: 'com.github.johnrengelman.shadow', version: '7.0.0']
> Failed to apply plugin 'com.github.johnrengelman.shadow'.
   > Project#afterEvaluate(Closure) on project ':rdf-delta-server' cannot be executed in the current context.

Gradle Build Script(s)

To recreate my issue, clone https://github.com/TopQuadrant-DevOps/rdf-delta and change the contents of ./rdf-delta-dist/build.gradle.kts to the below. Then run any task like ./gradlew clean.

plugins {
    base
    id("com.palantir.docker") version "0.26.0"
}

tasks.register<Tar>("packageDistribution") {
    dependsOn(":rdf-delta-server:shadowJar")
    dependsOn(":rdf-delta-fuseki-server:shadowJar")
    archiveBaseName.set("rdf-delta")
    from("dist")
    from("Files")
    from("README")
    with(copySpec {
        from(tasks.getByPath(":rdf-delta-server:shadowJar"))
        rename({ name -> "delta-server.jar" })
    })
    with(copySpec {
        from(tasks.getByPath(":rdf-delta-fuseki-server:shadowJar"))
        rename({name -> "delta-fuseki.jar" })
    })
    with(copySpec {
        from(project.file("../rdf-delta-examples/Tutorial"))
        into("Tutorial")
    })
    into("rdf-delta-${project.version}")
}

docker {
    name = "topquadrant/rdf-delta"
    files(tasks.getByName("packageDistribution").outputs)
}

Additional Notes

I see that Project#afterEvaluate is called specifically to exclude the Gradle API from being added to Shaded Jars, but perhaps it would be better to use this project's own filtering API. I don't mind doing the work here. I'm opening this ticket to get feedback on my thinking from the project owner.
