gradle 插件 DSL 中的参考版本变量？

Question

我有以下文件：

buildscript {
    ext {
        kotlinVersion = '1.2.10'
        springBootVersion = '2.0.0.M7'
    }
...

plugins {
    id "org.jetbrains.kotlin.jvm" version "1.2.10"

我想在 plugins 声明中使用 ext 块中的 kotlinVersion。我怎样才能做到这一点？

当我尝试直接这样做时，我得到： argument list must be exactly 1 literal non empty string

Answer 1

您不能在插件 DSL 中引用变量，

Plugin docs参考如下：

Where «plugin version» and «plugin id» must be constant, literal, strings and the apply statement with a boolean can be used to disable the default behavior of applying the plugin immediately (e.g. you want to apply it only in subprojects). No other statements are allowed; their presence will cause a compilation error.

Answer 2

使用pluginManagement块。 https://docs.gradle.org/current/userguide/plugins.html#sec:plugin_version_management
