无法在插件块中使用项目的额外属性 [英] Can't use project extra properties in plugin block

问题描述

我有一个多项目构建，并且经常发现自己锁定了针对工件的所有版本.因此，在我的根项目中，我定义了类似的内容:

I have a multi-project build, and more often than not I find myself locking versions for artifacts across the board. So in my root project I define something like:

project.extra.set("pkgVersions", mapOf(
    "kotlin" to "1.2.0",
    "jooq" to "3.10.2"
))

val pkgVersions : Map<String, String> by project.extra

plugins {
    base
    kotlin("jvm") version "1.2.0" apply false
}

虽然我可以在任何地方(包括其他子项目)使用pkgVersions:

While I can use pkgVersions anywhere, including other subprojects:

val pkgVersions by rootProject.extra

jooq {
    version = pkgVersions["jooq"]
}

我无法在插件块中这样做:

I am not able to do so inside a plugin block:

plugins {
    kotlin("jvm") version pkgVersions["kotlin"]
}

给我一​​个错误在此上下文中，隐式接收器无法调用pkgVersions.如果需要，请使用显式接收器".我假设这是因为隐式接收者可能应该是文件的JVM印象?但是，它使用的是PluginDependencySpec.尝试使用this@自动完成仅显示this@plugin.这只是我的一个长期猜测.但是，关于我应该做什么的任何指示?

Gives me the error "pkgVersions can't be called in this context by implicit receiver. Use the explicit one if required". I am assuming this is because the implicit receiver should probably be the file's JVM impression? But instead it is using PluginDependencySpec. Trying an auto-complete with this@ shows only this@plugin. This is just a long-shot guess from me. But, any pointers on what I am supposed to do?

同时，有一种方法可以在gradle-kotlin-dsl中创建全局类型，例如:

Also, while we are at it, is there a way to create a global type in gradle-kotlin-dsl, for instance:

data class MyBuildType(..)

，并且无需使用buildSrc就可以在任何地方使用它吗?使用buildSrc非常简单，我不介意使用它，只是想知道.

and have it available everywhere WITHOUT using buildSrc? It's pretty straightforward with buildSrc and I don't mind using it, but just wondering.

推荐答案

build.gradle.kts 根

buildscript {
  val kotlinVersion by rootProject.extra { "1.3.10" }
  ...
}

build.gradle.kts 模块

dependencies {
  implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk7:${rootProject.extra.get("kotlinVersion")}")
}
