Spring Boot无法使用Gradle Kotlin DSL解决Spring Boot的依赖关系

Question

build.gradle.kts 文件如下所示：

buildscript {
    val springBootVersion by extra("2.1.3.RELEASE")

    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:$springBootVersion")
    }
}

plugins {
    java
    id("org.springframework.boot") version "2.1.3.RELEASE"
}

apply(plugin = "io.spring.dependency-management")

错误消息是这样的：

* What went wrong:
Execution failed for task ':compileJava'.
> Could not resolve all dependencies for configuration ':detachedConfiguration1'.
> Cannot resolve external dependency org.springframework.boot:spring-boot-dependencies:2.1.3.RELEASE because no repositories are defined.
 Required by:
     project :

gradle版本为：

$ ./gradlew --version

Kotlin DSL:   1.1.3
Kotlin:       1.3.20
Groovy:       2.5.4
Ant:          Apache Ant(TM) version 1.9.13 compiled on July 10 2018

groovy dsl似乎工作正常。任何帮助将不胜感激。

Answer 1

删除无用的buildscript部分，并在内部版本 中指定存储库：

plugins {
    java
    id("org.springframework.boot") version "2.1.3.RELEASE"
}

apply(plugin = "io.spring.dependency-management")

repositories {
    mavenCentral()
}

Answer 2

我必须在 allProjects 部分中添加mavenCentral：

allprojects {
    repositories {
        mavenCentral()
    }
}

This post关于buildscript与所有项目的关系可以帮助阐明。
