gradle - 编写一个响应多个插件的 Gradle 插件

Question

我正在尝试编写一个新的 Gradle 插件，它需要应用两个插件：要么java或java-library，要么maven-publish。我正在用 Kotlin 编写插件。

我可以按照Gradle 指南轻松地使插件对单个插件应用程序做出反应：

project.plugins.withType(MavenPublishPlugin::class.java) {
    // My stuff
}

但是对于需要两个插件应用程序，我不能做同样的事情：

project.plugins.withType(JavaPlugin::class.java) {
    project.plugins.withType(MavenPublishPlugin::class.java) {
        // My stuff
    }
}

在第二种情况下，启动：

案例一：如预期

plugins {
    id("java")
    id("maven-publish")
    id("org.danilopianini.publish-on-central")
}

按预期运行插件

案例 2：未应用，如预期的那样

使用：

plugins {
    id("java")
    id("org.danilopianini.publish-on-central")
}

正如预期的那样，不应用插件

案例3：应用了，应该没有

但是，最后：

plugins {
    id("maven-publish")
    id("org.danilopianini.publish-on-central")
}

尝试应用插件并失败：

这在我看来是尝试应用插件，不管 Java 插件没有被应用。

您知道任何配置插件以响应多个插件应用程序的方法吗？
