How can I get a gradle 5 precompiled script plugin get to work when it is in a package

Question

I want to modularize my build.gradle.kts files by using the precompiled script plugins feature introduced with gradle 5.3.1.

It works fine when I have my simple hello-world.gradle.kts file in buildSrc/src/main/kotlin directly

tasks.register("hello-world") { println("hello world") }

and include it in the plugins section of my main build.gradle.kts:

plugins {
   `hello-world`
}

I can now use gradle hello-world and see the expected output.

But when I place the same script in buildSrc/src/main/kotlin/custom/hello-world-custom.gradle.kts (adding package custom to the script) it fails, although the documentation states:

Likewise, src/main/kotlin/my/java-library-convention.gradle.kts would result in a plugin ID of my.java-library-convention as long as it has a package declaration of my.

The main build.gradle.kts:

plugins {
   `custom.hello-world-custom`
}

but instead, I get an error:

 Script compilation error:

  Line 3:   `custom.hello-world-custom`
        ^ Unresolved reference: `custom.hello-world-custom`

Any ideas how to fix this?

Update: to reproduce this, I created a small repo with different "hello world" tasks.

文档中不太清楚，但我找到了解决方案：

包必须在反引号之外定义：

plugins {
 `hello-world`
 custom.`hello-world-custom`
}
