gradle - 如何在 Gradle Kotlin DSL 中使用来自 gradle.properties 的插件版本？

Question

现在我用这种方式:

plugins {
    val kotlinVersion: String by project
    val springBootPluginVersion: String by project
    val springDependencyManagementPluginVersion: String by project

    id("org.jetbrains.kotlin.plugin.allopen") version kotlinVersion
    id("org.jetbrains.kotlin.jvm") version kotlinVersion
    id("org.springframework.boot") version springBootPluginVersion
    id("io.spring.dependency-management") version springDependencyManagementPluginVersion
}

此变体可以编译并运行，但我不知道这种方式是否正确以及为什么 IntelliJ IDEA 在放置版本定义的行上显示错误:

'val Build_gradle.project: Project' can't be called in this context by implicit receiver. Use the explicit one if necessary

有几个问题对此有一些详细信息:

gradle/kotlin-dsl#480

gradle/gradle#1697

在最新版本的 Gradle 中执行此操作的方法是使用 settings.gradle或 settings.gradle.kts和 pluginManagement {}块。

在你的情况下，它可能看起来像:

pluginManagement {
  resolutionStrategy {
    eachPlugin {
      when (requested.id.id) {
        "org.jetbrains.kotlin.plugin.allopen" -> {
          val kotlinVersion: String by settings
          useVersion(kotlinVersion)
        }
        "org.jetbrains.kotlin.jvm" -> {
          val kotlinVersion: String by settings
          useVersion(kotlinVersion)
        }
        "org.springframework.boot" -> {
          val springBootPluginVersion: String by settings
          useVersion(springBootPluginVersion)
        }
        "io.spring.dependency-management" -> {
          val springDependencyManagementPluginVersion: String by settings
          useVersion(springDependencyManagementPluginVersion)
        }
      }
    }
  }
}
