我已经成功地发布到Artifact Registry，我可以在“正常”使用中使用Artifact：dependencies { implementation("mygroup:myartifact:myversion") }。
我的问题是插件。我创建了一个插件。我可以成功地将其发布到Artifact Registry和Maven local。我可以从Maven本地使用它，但是我不能让我的构建脚本从Artifact Registry获取它。

buildscript {
    repositories {
        maven(url = uri("artifactregistry://us-west1-maven.pkg.dev/glitchy-maven/repo"))
    }
}

plugins {
    id("com.google.cloud.artifactregistry.gradle-plugin") version "2.1.1"
    id("com.glitchybyte.gradle.plugin.buildinfo") version "1.0.0"
    `java-library`
}

我得到：

* What went wrong:
Plugin [id: 'com.glitchybyte.gradle.plugin.buildinfo', version: '1.0.0'] was not found in any of the following sources:

- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Plugin Repositories (could not resolve plugin artifact 'com.glitchybyte.gradle.plugin.buildinfo:com.glitchybyte.gradle.plugin.buildinfo.gradle.plugin:1.0.0')
  Searched in the following repositories:
    Gradle Central Plugin Repository

因此，它不会在Artifact Registry中查找插件。我知道我错过了什么，但我不知道是什么。
更新...
我从build.gradle.kts中删除了buildscript，并将其添加到settings.gradle.kts中：

pluginManagement {
    plugins {
        id("com.google.cloud.artifactregistry.gradle-plugin") version "2.1.1"
    }
    repositories {
        maven(url = uri("artifactregistry://us-west1-maven.pkg.dev/glitchy-maven/repo"))
    }

我得到：
