如何将ext。*变量转换为build.gradle.kts中的插件块 [英] How to get ext.* variables into plugins block in build.gradle.kts

问题描述

我的构建文件如下所示：

  val nexusBaseUri：String by extra $ b $ val gradle_version：String by extra 
 val kotlin_version：String by extra 
 
 buildscript {
 val nexusBaseUri by extra {https：// mynexusserver / nexus} 
 val gradle_version by extra {4.1 } 
 val kotlin_version by extra {1.1.4-3} 
 val springBoot_version by extra {2.0.0.M3} 
 
 repositories {
 maven {url = uri（$ nexusBaseUri / repository / public）} 
 jcenter（）
 maven {url = uri（http://repo.spring.io/snapshot）} 
 maven {url = uri（http://repo.spring.io/milestone）} 
} 
依赖项{
 classpath（org.springframework.boot：spring-boot -gradle-plugin：$ springBoot_version）
 classpath（org.jetbrains.kotlin：kotlin-gradle-plugin：$ kotlin_version）
 classpath（org.jetbrains.kotlin：kotlin-allopen：$ kotlin_version）
} 
} 
 
插件{
应用程序
 // vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv 
 //以下行导致问题
 // vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv 
 kotlin（jvm，kotlin_version）
 $ b插件（kotlin-spring）
插件（org.springframework.boot）
插件（io.spring。依赖关系管理）
} 
 
应用程序{
 mainClassName =eqip.fid.FdmlInterpreterDeveloperAppKt
} 
 
储存库{
 maven {url = uri（$ nexusBaseUri / content / groups / public）} 
 jcenter（）
 maven {url = uri（http://repo.spring.io/snapshot ）} 
 maven {url = uri（http://repo.spring.io/milestone）} 
} 
 
依赖项{
 compile（kotlin（ stdlib））
 compile（org.springframework.boot：spring-boot-starter-web）
} 
 
 tasks {
wrapper（ Wrapper :: class）{
 gradleVersion = gradle_version 
} 
} 
  

我在IntelliJ IDEA中遇到的错误是： b
$ b

'val kotlin_version：String'can not be在这种情况下由隐式接收器调用。

如何解决这个问题？

解决方案

您可以在插件中定义一个版本，然后使该版本可以在博客以外访问，例如在依赖关系部分。

 插件{
 kotlin jvm）。version（1.1.61）
} 
 
 //这是使版本在其他地方可用的必要条件
 val kotlinVersion：String？由额外{
 buildscript.configurations [classpath] 
 .resolvedConfiguration.firstLevelModuleDependencies 
 .find {it.moduleName ==kotlin-gradle-plugin} ?. moduleVersion 
 } 
 
依赖关系{
 compile（kotlin（stdlib，kotlinVersion））
} 
  

对于版本1.2+，您必须替换为 kotlin-gradle-plugin org.jetbrains.kotlin .jvm.gradle.plugin

My build file looks like this:

val nexusBaseUri: String by extra
val gradle_version: String by extra
val kotlin_version: String by extra

buildscript {
    val nexusBaseUri by extra { "https://mynexusserver/nexus" }
    val gradle_version by extra { "4.1" }
    val kotlin_version by extra { "1.1.4-3" }
    val springBoot_version by extra { "2.0.0.M3" }

    repositories {
        maven { url = uri("$nexusBaseUri/repository/public") }
        jcenter()
        maven { url = uri("http://repo.spring.io/snapshot") }
        maven { url = uri("http://repo.spring.io/milestone") }
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:$springBoot_version")
        classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version")
        classpath("org.jetbrains.kotlin:kotlin-allopen:$kotlin_version")
    }
}

plugins {
    application
    // vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
    // the following line causes a problem
    // vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
    kotlin("jvm", kotlin_version)
}

apply {
    plugin("kotlin-spring")
    plugin("org.springframework.boot")
    plugin("io.spring.dependency-management")
}

application {
    mainClassName = "eqip.fid.FdmlInterpreterDeveloperAppKt"
}

repositories {
    maven { url = uri("$nexusBaseUri/content/groups/public") }
    jcenter()
    maven { url = uri("http://repo.spring.io/snapshot") }
    maven { url = uri("http://repo.spring.io/milestone") }
}

dependencies {
    compile(kotlin("stdlib"))
    compile("org.springframework.boot:spring-boot-starter-web")
}

tasks {
    "wrapper"(Wrapper::class) {
        gradleVersion = gradle_version
    }
}

The error I get in IntelliJ IDEA is

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

How do I fix this?

解决方案

You can define a version inside plugins and then make this version accessible outside of the blog, e.g. in the dependencies section.

plugins {
    kotlin("jvm").version("1.1.61")
}

//This is necessary to make the version accessible in other places
val kotlinVersion: String? by extra {
    buildscript.configurations["classpath"]
            .resolvedConfiguration.firstLevelModuleDependencies
            .find { it.moduleName == "kotlin-gradle-plugin" }?.moduleVersion
}

dependencies {
    compile(kotlin("stdlib", kotlinVersion))
}

for version 1.2+, you will have to replace with kotlin-gradle-plugin org.jetbrains.kotlin.jvm.gradle.plugin
