spring-boot - Spring Boot 无法使用 gradle kotlin dsl 解决 spring-boot-dependencies

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")

错误信息是这样的：

* 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.

毕业版本是：

$ ./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buildscript无用的部分，并在构建中指定存储库：

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部分添加 mavenCentral：

allprojects {
    repositories {
        mavenCentral()
    }
}

这篇关于 buildscript vs allprojects 的帖子可以帮助澄清。
