spring-boot - Gradle 无法识别 springboot buildInfo 插件

问题描述

我正在尝试将springboot buildInfo插件添加到我的build.gradle.kts，以便我可以生成文件并通过端点build-info.properties公开构建信息（即应用程序版本） 。/actuator/info但是，当我添加 buildInfo 插件时，我不断收到以下错误：

Unresolved reference: springBoot

我一直在参考以下Spring 文档，但它只是说只需添加插件并构建。

我是否将插件放在我的 gradle 文件中的正确位置？我是否需要另一个依赖项或插件引用才能使其正常工作？

这是我的主要部分的build.gradle.kts样子：

group = "com.walmart.muse.core-kt"
version = getLatestTagVersion()
java.sourceCompatibility = JavaVersion.VERSION_1_8
java.targetCompatibility = JavaVersion.VERSION_1_8

plugins {
    id("org.springframework.boot") version "2.2.0.RELEASE" apply false
    kotlin("jvm") version "1.3.50"
    kotlin("plugin.spring") version "1.3.50"
    kotlin("plugin.jpa") version "1.3.50"
    kotlin("plugin.allopen") version "1.3.50"
}

// This little code block is what is causing the error. 
// I want to use it to get buid-info.properties so I can hit `/actuator/info` 
// to expose my build info, but this isn't working :(
springBoot {
    buildInfo()
}

解决方案

原因是，您使用applygradle doc https://docs.gradle.org/current/userguide/kotlin_dsl.html#sec:kotlin_using_standard_api现在 gradle-kotlin-dsl 不能使用类型安全访问器。

代替

springBoot {
   buildInfo()
}

在build.gradle.kts你必须使用

configure<org.springframework.boot.gradle.dsl.SpringBootExtension> {
  buildInfo()
}
